BMW’s New Vision: 155-MPH Plug-In Hybrid
We were as shocked as anyone when BMW announced it was quitting Formula 1 to devote more resources to developing cleaner, greener automobiles. There was some skepticism, but BMW wasn’t blowing green smoke. It’s serious about building eco-friendlier pavement-peeling cars.
First up is a slick 356-horsepower all-wheel-drive plug-in diesel-hybrid concept that BMW claims accelerates like an M3, sips gas like a Toyota Prius and can go 31 miles on battery power alone. It’s called the Vision Efficientdynamics Concept, and we’ll see it later this month at the Frankfurt auto show.
No, Vision Efficientdynamics Concept doesn’t exactly roll off the tongue. But the name aside, BMW has a dynamite idea on its hands here.
The EfficientDynamics is a 2+2 four-door hybrid that combines M Series performance with better fuel efficiency and less emissions than you see in many compacts. BMW performs this magic by marrying its ActiveHybrid technology with an extremely economical engine and excellent aerodynamics. The result is a concept car with a top speed governed at 155 mph and a zero-to-62 acceleration time of 4.8 seconds. More impressive, the car gets 62.2 mpg and emits a Prius-like 99 grams of CO2 per kilometer.
Power comes from a 1.5-liter direct injection 3-cylinder turbodiesel engine and an electric motor on each axle. The engine was small to squeeze in between the rear seat and the rear axle, which should make the Efficientdynamics Concept very agile. The diesel puts out 163 horsepower and 214 pound-feet of torque. Add in the motors and total output is 356 ponies and a stump-pulling 590 pound-feet, though you can only get that much power in short bursts. The car has all-wheel-drive when running in electric mode. BMW says the car can run on the diesel engine, either one of the electric motors or any combination of the three.
The lithium-polymer battery pack sports 98 cells. It delivers 8.6 kilowatt-hours for driving the car, and BMW says the serial arrangement of cells has gross storage capacity of 10.8 kilowatt-hours. The pack weighs 187 pounds and BMW says it doesn’t need an active cooling system. BMW says the battery recharges in 2.5 hours at 220 volts.
All that tech is housed in a body designed with some serious inspiration from BMW’s Formula 1 cars. BMW says the Vision has a drag coefficient of 0.22, aided in part by the myriad vanes and ducts. People are going to love it or hate it, but you’d expect nothing less from BMW even without controversial designer Chris Bangle around anymore.
So far the Vision is just a concept. Still, BMW has made it clear it plans to make sustainability a cornerstone of its lineup, so we’re sure to see some of the technology in road cars before long.

Earlier on, luxury car buyers didn’t have much of an option. Chose
only the Mercedes and the occasional illegally imported Lexus. Now, it’s
a different story altogether. Right from the entry level buyers to the
top end luxury class, there is a spade of choices. For the entry level
buyer, there is the Nano, Alto and other cars while for the top end
luxury class buyer, there is the Maybach, Bentley and Rolls Royce
awaiting them. So much for competition that these manufacturers don’t
even advertise their products. Here we are referring to the top end ones
and not the entry level. In between the midlevel executive class luxury
buyer has got the choice of going in for the BMWs, Audis and also the
Mercedes with the occasional Volvo or Jaguar
thrown in for good measure. In the Indian market, there is a new launch
and it is the 2011 Audi A6. No sooner after its launch, its inevitable
that we don’t compare it with its other German compatriots. Well, it’s a
known fact that even buyers in this segment go in for the diesel
powered cars more than the petrol engined ones for the sheer fuel
economy they provide. The 2011 BMW 530d in India and the 2011 Mercedes E350 in India are not too pleased with the 2011 Audi A6 in India
and would want to sort out their issues via a duel. We just provided
them a platform here. All these are top end diesel models even though
the manufacturers provide lower variants with different engines and
stuff.
Minimalistic is the theme for both the Merc and BMW. The BMW’s cabin boasts of a having being focused on the driver part. For a driver, the most important thing is to concentrate on the job of driving rather than look around and try to understand which button stands for which. The wide and accommodating proportions of the BMW definitely are a good thing for those with minor back problems. The minor part was stressed on since the lower part of the seat is actually very hard. The sultry voice guidance system from the navigation part provided is soothing and also accurate. Ohh, the party trick in this car is the headsup display. The rear seats have got an ingress egress problem wherein one has to hop over the middle hump to have any sort of comfort. However, once seated there, its almost like a lounge. But then the high windowline and also the massive front seats in your face thing does make it a kinda cooped up.
Amongst all these cars, the Mercedes E350’s interior feel a bit boring. There is not much of lighting gimmick inside here and plus the muddy brown color is detested by many. But then on the practical side, it does work wonders considering that there is less of cleaning involved for them. Just like the Audi, use of materials is fantastic barring a few bits here and there. Looking at the 3 pointed star down the long bonnet has always got to be a special feeling. As discussed before, the Merc does fall short on various goodies offered by the others here with its spastic COMAND system also no navigation system , reverse camera and other stuff. But then the seats in the Mercedes are very comfortable and once in them, we immediately forgave the car for its lack of features. Boot space is more or less evenly handled by all the 3 here.
For ride quality, it is always the Mercedes that seems composed of the lot. There are not many electronics guiding the shock absorbers and hence the traditional technology does the trick here. Though the steering wheel may not be the most communicative unit in the market right now, it has a surprisingly easy going feel to it and infact instills some confidence in the driver. Body roll is well controlled and though the car has a fondness for taking things slowly, its there but for sure. Something akin to the Mercedes asking you to take things in a slower manner rather than go outright and treat it as a racing machine. As far as NVH is concerned, the Mercedes is the quietest of the lot followed by BMW and then Audi.
The E350 has a slow gearbox which has a mind of its own. We have repeated it in almost all the comparisons and tests that this gearbox is best left on its own, since putting it to semi manual mode rarely makes a difference to the throttle response or stuff. The BMW’s steering wheel may not be as communicative as the previous generation ones but then the 8 speed gearbox is definitely more at home on the highway. The same way the previous generation steering wheel had a telepathic effect, the same way the 8 speed autobox senses when the driver wants to downshift or even upshift. For the records, the 0-100 kmph dash is completed in the Audi before the BMW catches it up and then finally the Mercedes comes puffing to make the rear. Due to its taller 8th gear, the BMW is able to achieve a higher top speed as well.
As for the safety equipments, all the three cars here have got it in safe amounts with the Mercedes feeling sparsely equipped out of all the three cars here. Its got the PreSafe thing going for it wherein upon sensing a collision, all the doors are rechecked to see if they are bolted on properly and also the open windows and sunroof are also closed. There are no reverse cameras and stuff . 6 airbags is a common stuff for all the three cars here and all the cars here have an excellent crash test ratings from the European unions.
As for the fuel efficiency, the Audi trumps the others here. The Mercedes is the least fuel efficient returning an overall 11.3 kmpl compared to the 11.8 kmpl by the BMW and 12.2 kmpl by the Audi. Did anyone say that power and fuel efficiency don’t go hand in hand?
Looks
All these cars here ape their bigger brother as far as the exteriors go. The E looks a lot like the S, the 5 looks similar to the 7 and the A6 is just about smaller than the A8. The new Audi A6 definitely is the longest as also the widest in this comparison, not that it would be felt immediately coz of the tight packaging done by Audi designers. As for being the hideous Goliath of the bunch, the BMW overshadows the Audi. With its designers showering their design frame with liberal strokes, the 5 series looks bulbous. The E and the A6 both looks slimmer than it. Infact, the E-class is the narrowest of all the cars featured here for the test and it looks the part as well. The alloy wheel design of all the three cars here is similar and the Audi sports the weediest tyres here with the size rating of 225/55-R17s. All the three cars also come with the proprietary LED technology for their headlamps. Moreover, their tail lamps are also fitted with the highest quality LED lamps. The BMW boasts of a clustered twin tail pipe configuration while the others have dual exhausts at both the sides. We personally favor the arrangement of the tail lamps in the BMW. The E-class has got a too modest tail lamp cluster. All the three have radio antenna clusters towards the rear windscreen, something which BMW started with their cars.Interiors
Though its very tough to distinguish the exteriors of the old A6 and the new one for a layman, in the interiors, anyone would be able to tell apart the difference. The new 2011 Audi A6 in India has got the interior quality up from its previous generation model, though some flimsy bits like the plastics for the electric seat arrangement and stuff. But that’s easily dismissible, since most of the times, it’s the chauffer doing the driving here. The front seats are supportive and overall the dash looks sporty in its approach. We would have however liked a bit more of the lights gimmick found in the much more expensive Audi A8. However, Audi says that with the interior lighting package worth Rs 3lakhs extra, the interior can be brought upto the standards of the A8.The rear seats however, are not so promising. They do have enough of leg room as also head room but then the underthigh support can be found lacking. This is immediately evident after one sits in the Audi after an excursion in both the Mercedes and BMW. The MMI interface in the Audi has far more clarity than the iDrive system in the BMW and also the useless COMAND system in the Mercedes. Overall the cabin fare in the Audi reeks of spaciousness and also a clear vision with almost no blind spots dialed in.Minimalistic is the theme for both the Merc and BMW.

Handling and ride quality
Anyone going up against BMW in the handling front know that they would have a high standard to match to. That saying, over the years, the BMW 530d has lost much of its charm in this department. The biggest change is the adoption of an electronic power steering, something which dampens the entire feeling of driving a BMW car. For the off-center, the steering is sharp to respond. It has lost that heavy feeling at lower speeds. One more surprising thing is that this Beemer doesn’t seem to be liking high speeds and has some serious stability issues with all the testers remarking that the car seems to be wafting. Nothing wrong with the air pressure or even the run flats. At low speeds, surprisingly for a BMW, the ride quality was very compliant. However, much of vertical movement could be felt at higher speeds. The Audi A6’s adaptive suspension does the trick here with the car displaying a good ride quality at lower speeds and also being more absorbent as the speeds increase. However, the extensive use of aluminium has also brought about a lightness in the way things are handled and more often than not, the larger bumps are transmitted to the cabin. Moreover, the noise insulation in the Audi is not as good as that of the Mercedes or even the Beemer. The steering wheel of this car is not that confidence inspiring and is more like its predecessor.For ride quality, it is always the Mercedes that seems composed of the lot. There are not many electronics guiding the shock absorbers and hence the traditional technology does the trick here. Though the steering wheel may not be the most communicative unit in the market right now, it has a surprisingly easy going feel to it and infact instills some confidence in the driver. Body roll is well controlled and though the car has a fondness for taking things slowly, its there but for sure. Something akin to the Mercedes asking you to take things in a slower manner rather than go outright and treat it as a racing machine. As far as NVH is concerned, the Mercedes is the quietest of the lot followed by BMW and then Audi.
Engine, performance and fuel efficiency
A 3.0 liter inline 6 cylinder engine is what comprises the BMW 530d’s engine. 245 Bhp and 550 Nm are the figures for the power and torque respectively. The gearbox used here is an 8 speed auto one. For the 2011 Audi A6 in its 3.0 liter diesel trim, the motor makes a similar to the BMW’s 245 Bhp and 510 Nm of torque. It uses a DSG 7 speed auto box. The E350 CDI in the meanwhile makes do with 231 Bhp and 550 Nm of torque. It uses the conventional torque converter with 7 ratios to play with. Though the E lacks in Bhp, it makes do with a higher torque rating and is an effortless thing to pilot around. When you want the kick in your back feeling, then the E would feel ashamed of itself and curl in a corner and die. Its not for those kick inducing actions but only for the usual cruising and commuting. For the kick action, its either the Beemer or even the Audi. The Audi has got a wide powerband, however, we could rarely use it to its redline. In stark contrast, the Beemer’s engine is far more rev happy and occasional visits to the redline could be seen. The Audi’s engine combines the best of both worlds in the sense that the panache of the Mercedes is there and also the urgency of the BMW. The DSG gearbox is also a good one and rarely are shifts mistimed or stuff.The E350 has a slow gearbox which has a mind of its own. We have repeated it in almost all the comparisons and tests that this gearbox is best left on its own, since putting it to semi manual mode rarely makes a difference to the throttle response or stuff. The BMW’s steering wheel may not be as communicative as the previous generation ones but then the 8 speed gearbox is definitely more at home on the highway. The same way the previous generation steering wheel had a telepathic effect, the same way the 8 speed autobox senses when the driver wants to downshift or even upshift.

Due to its taller 8th gear, the BMW is able to achieve a higher top speed as well.
As for the safety equipments, all the three cars here have got it in safe amounts with the Mercedes feeling sparsely equipped out of all the three cars here. Its got the PreSafe thing going for it wherein upon sensing a collision, all the doors are rechecked to see if they are bolted on properly and also the open windows and sunroof are also closed. There are no reverse cameras and stuff . 6 airbags is a common stuff for all the three cars here and all the cars here have an excellent crash test ratings from the European unions.
As for the fuel efficiency, the Audi trumps the others here. The Mercedes is the least fuel efficient returning an overall 11.3 kmpl compared to the 11.8 kmpl by the BMW and 12.2 kmpl by the Audi. Did anyone say that power and fuel efficiency don’t go hand in hand?
Verdict
Like we have always mentioned, all the manufacturers definitely try and up the game before they launch their products. Its actually a shamus that Mercedes are doing precious little in upgrading the power and fuel efficiency of their cars plus they are way behind in the interior trims and also the features. Also, Mercedes cars are charged a bomb as compared to the others here. We would wistfully lust after the Audi, were it not for the excess of aluminium used in the cabin which makes it somewhat unsuitable for the Indian roads since aluminium has a far greater displacement than steel. Of all these cars, the one with the least aluminium content is the Mercedes and its build quality still stands out. The BMW has a better build quality than the Audi. All said and done, Mercedes are the proved ones in the Indian market as of now and owning a 3 pointed star is definitely one of the highpoints of any person who wants to announce that they have arrived in life. The 2011 Audi A6 price in India for its 3.0 TDI engine is Rs 53.00 lakhs (this is the estimated price since Audi haven’t disclosed the price yet). The 2011 Mercedes E350 CDI price in India is Rs 51 lakhs while the 2011 BMW 530d price in India stands at Rs 48.50 lakhs. All these prices are ex-show room, Mumbai.
The official design images and information on the BMW i8 Concept, the 2+2 sportscar that features an advanced hybrid technology with sporty performances and high fuel efficiency.From the official Press Release:
The exterior design features a flat silhouette, with sweeping lines, taut surfaces and precise edges that form an extremely sculptural and organic surface structure.
The individual vehicle components are clearly visible from the outside, the black and transparent Life module setting itself apart from the silver-colored body components around it.
The precise lines along its flanks and hallmark BMW i “stream flow” also give the BMW i8 Concept a strong sense of powering forward.
A large, transparent greenhouse lends the exterior a feeling of lightness and highlights the efficiency of the vehicle.
The BMW i8 Concept’s doors swing upwards like wings: below them, the silver-colored layer moulds the car’s flanks into a powerful wedge shape, opening out from the door sills towards the rear.
A blue flourish accentuates the dynamic presence of the sills.
Together, the bonnet and door sill sculpting emphasise the BMW i8 Concept’s forward- surging stance, and their smooth lines imbue the car with a touch of lightness.
At the front, a number of different levels interact with one another, while the expressive surface treatment exudes dynamic verve and advertises the car’s sporting potential.
The full-LED headlights of the BMW i8 Concept are designed as two U-shaped configurations.
A black, semi-transparent “V” rises out of the hood just behind the kidney grille, opening out towards the windscreen and guiding the eye to the electric motor below.
The “V” also offers the first glimpse of the CFRP module and extends back towards the rear like a black band to provide a visual connection between the different sections of the car.
Similarly to the front end, the rear of the car is also very low, horizontal and sculptural in design.
The silver-coloured side sections form a striking vertical frame around the rear of the car, with a precise line extending out to the sides enjoying particular prominence.
In its center the silver-coloured and blue- framed rear diffuser is a wider and lower interpretation of the version on the BMW i3 Concept, adding a distinct sporting flavour to its relationship with its stablemate.
At the rear, the car’s exceptional sporting credentials are also expressed in width-accentuating lines, three-dimensional air outlets and “floating” tail lights with air through-flow.
The tail lights, which also have a distinct horizontal design, are integrated into the upper layer of the rear and share the signature U-shape of the BMW i light concept.
The transparent surfaces in the doors and roof give the exterior and interior design of the BMW i8 Concept the appearance of merging into one another.
The colour concept and underlying structure of the BMW i8 Concept interior closely mimic those of the BMW i3 Concept.
Here again, the Porcelain White support structure, black technical level and comfort section with Mocha Brown leather are split into three different layers.
The arrangement of the air vents, control panels and displays also betrays the car’s family ties to its BMW i3 Concept sibling.
Overall, however, these features have a more sporting character and are geared much more clearly towards the driver.
Driver- relevant functions such as the gearshift lever, start-stop button and parking brake are arranged around the driver on the centre console and are graphically strongly geared towards the driving seat as well.
The three-dimensional displays are extremely clear and flash up the relevant information for the driving situation at hand.
At the same time, occupants in the BMW i8 Concept sit in a highly integrated position low down in the car and are separated by the battery running lengthways through the interior.
This longitudinal bisection of the cabin underlines the sporting and forward-looking character of the BMW i8 Concept interior.
The 8.8-inch (22.4 cm) freestanding information display in the dash is joined by an equally large display taking the role of the instrument cluster.
Designing the central instruments in this way enables driver-relevant information to be conveyed in a three-dimensional and high-resolution format.

In keeping with BMW i style, the displays are premium, modern and purist. Depending on the driving mode, the two drive systems are depicted by a pair of ellipses, which supply information on their operation at any given time. Other information – such as the available range and fuel level – can be found here, too.
The i8 Concept features a plug-in hybrid powertrain that combines a 96 kW / 250 Nm electric motor with a 164 kW/220 hp turbocharged three-cylinder gasoline engine developing up to 300 Nm and 300 Nm of torque driving the rear axle.
Together, the two drive units allow the i8 to reach a top speed limited to 250 km/h (155 mph), to accelerate from 0 to 100 km/h (62 mph) in under five seconds while achieving a fuel consumption in the European cycle of under three litres per 100 kilometres (approx. 94 mpg imp).
The BMW i8 Concept can also run purely on electric power, with a driving range of approximately 35 kilometres (20 miles). The battery can be fully recharged in two hours at a standard power socket.

At the same time, occupants in the BMW i8 Concept sit in a highly integrated position low down in the car and are separated by the battery running lengthways through the interior.This longitudinal bisection of the cabin underlines the sporting and forward-looking character of the BMW i8 Concept interior.
The 8.8-inch (22.4 cm) freestanding information display in the dash is joined by an equally large display taking the role of the instrument cluster.
Designing the central instruments in this way enables driver-relevant information to be conveyed in a three-dimensional and high-resolution format.
In keeping with BMW i style, the displays are premium, modern and purist. Depending on the driving mode, the two drive systems are depicted by a pair of ellipses, which supply information on their operation at any given time. Other information – such as the available range and fuel level – can be found here, too.
Technical Features
The i8 Concept features a plug-in hybrid powertrain that combines a 96 kW / 250 Nm electric motor with a 164 kW/220 hp turbocharged three-cylinder gasoline engine developing up to 300 Nm and 300 Nm of torque driving the rear axle.Together, the two drive units allow the i8 to reach a top speed limited to 250 km/h (155 mph), to accelerate from 0 to 100 km/h (62 mph) in under five seconds while achieving a fuel consumption in the European cycle of under three litres per 100 kilometres (approx. 94 mpg imp).
The BMW i8 Concept can also run purely on electric power, with a driving range of approximately 35 kilometres (20 miles). The battery can be fully recharged in two hours at a standard power socket.

First introduced as the “Megacity Vehicle”, the i3 will be BMW’s first series-produced all-electric car., and is expected to hit the market in 2014.
Primarily designed for urban areas, the i3 is based on the new LifeDrive architecture concept – also adopted on the i8 – which consists of two separated parts: the “Life” module, that houses the passenger compartment, and the “Drive” module, which integrates the powertrain.
In the i3 the two modules are arranged one on top of the other. The Drive module mainly consists of the large battery, which is located in the underfloor section, which contributes to lower the center of gravity and achieve a better weight distribution.
The electric motor powers the rear axle and delivers an output of 125 kW/170 hp and a torque of 250 Nm (184 lb-ft), allowing the i3 to accelerate from 0 to 60 km/h (37 mph) in under four seconds and from 0 to 100 km/h (62 mph) in less than eight seconds.
The side view is characterized by a dynamic wedge shape, underlined by the large greenhouse that tapers towards the rear, the rearwards-rising door sills and the “stream flow” – a dynamic stroke descending from the roof into the C-pillar.
The flowing silhouette and the long wheelbase hint at the generous levels of interior space, while the “coach doors” with opposing construction and no B pillars makes it easier to access the cabin.
“The design reveals the driving pleasure on offer with electromobility. And you can add to that a large and practical interior.” says Benoit Jacob, Head of BMW i Design Team.
Extensive glass surfaces and black elements like the window surrounds and door sills give the vehicle a feeling of lightness and, together with the exposed carbon structures, draw attention to its low weight.
At the same time, the lack of B-pillars ensures a seamless transition between the two doors.
The result is a large, homogeneous glass surface, which gives the car’s flanks a very transparent look.
Large, narrow 19-inch wheels add further impact to the dynamic side profile of the BMW i3 Concept.
Their slim construction allows them to reduce the car’s drag and rolling resistance, and to avoid encroaching into the interior. And that means more space for the passengers.
The front end of the BMW i3 Concept has a very clear and uncluttered design and is dominated by the kidney grille, which has the hallmark BMW i blue background and – thanks to the car’s all-electric drive system – is totally blanked off.
“The grille also has a conspicuous swage line picking up from the bonnet edge. Below the kidney grille, the silver-coloured outer layer lends the sculptural front apron its form.
“The precise, vertical edges of the front apron element serve as the vehicle’s side borders and reinforce its powerful stance on the road.
“Black surfaces identify the functional areas of the front end, such as the load compartment under the bonnet and the air inlets.
“Along with the kidney grille, the U-shaped LED-backlit lines form an important part of the arresting new BMW i face. The minimalist interpretation of the individual headlights underlines the efficiency and lightness of the BMW i3 Concept and lends it an individualist, outward-looking and reputable air.”
The rear end has a large, retractable rear window that offers optimum access to the luggage compartment, while the roof pillars stand upright to create as much space as possible in the interior.
Its large glass area allows the rear window to offer unbeatable rear visibility. The rear window is also home to the tail lights, which are U-shaped (like the headlights) and appear to be floating in the glass.
Behind it lies an extremely versatile boot area, whose capacity can be further increased by folding down the rear seats.
The wide, silver-colored rear diffuser marks the body’s lowest edge and increases the aerodynamic efficiency. Bordered by a blue layer, the diffuser tapers heavily towards the road and appears to continue underneath the car.
The form of the diffuser underlines the car’s powerful stance. A sportier version can be found on the BMW i8 Concept, forging a link between the two models.
The Life module is characterized by an airy and lounge-like character.
Among the features are the use of renewable raw materials – such as the natural fibers used for the instrument panel and door panelling.
The naturally tanned leather of the seats contributes to the lounge-style ambience and provides a contrast to the clear, “floating” forms of the instrument panel and door elements.
Given the absence of a center tunnel, the two front and two rear seats are connected with each other by a continuous seat surface, which also allows for ease of entry and exit via the front passenger side, when parking close to walls, for example.
