BMW’s tech-heavy gas-electric coupe moves closer to

It’s been nearly two since BMW’s Vision concept debuted at the 2009 show, and the car has now officially re-emerged one closer to production as the BMW i8 concept. As you can little has changed in the styling In fact, other than a new design, the only other change we’ve spotted the doors, which seem to claimed some territory their bottoms and thereby the size of the blue body-side

Interestingly, the car didn’t show change when BMW paraded it for spy photographers this past but we like it.

Passenger Compartment + = LifeDrive

As with the i3 city car that debuted at the same (you can read about it in here ), the story of the i8 begins its so-called LifeDrive architecture. BMW that its experiences in creating the E and 1-series-based BMW ActiveE showed adapting cars engineered for power to electric propulsion in a lot of excess weight and compromises in As a result, both the i8 and i3 are built two purpose-built modules: one to house dubbed “Life,” and one for propulsion and components, called “Drive.” them, and you have a carand “LifeDrive” branding.

While the i3 and i8 share the LifeDrive philosophy, the cars differ in That’s because the i3 is fully while this i8 is a plug-in The i8’s powertrain is split its two axles, with an electric and direct-drive transmission at the front and a gas engine and transaxle at the rear.

the battery packs in the i3 and i8 use different chemistries, as well as unique The large, square pancake of the i3 is designed for longer distance other words, it has a lot of energyand is below the passenger compartment. In the i8’s lithium-ion cells into the coupe’s Life where, as in the Chevrolet Volt, the and -heated battery stack a hump that could be for a transmission tunnel.

The i8’s pack is designed to deliver of power in short spurts; the spec is yet to be decided, but it should a capacity of around 8 kWh.

Arranging the pack this way BMW’s engineers to achieve yet claim of perfect 50/50 distribution, thereby preserving in the city of Munich. As in the i3, the i8’s components are largely crafted of while the Life module a carbon-fiber skeleton wrapped in exterior panels.

So much material allows the i8 to use a smaller, battery than would be if the car were made of heavier This frees up room in the and, more important, the curb weight around a 3300 pounds. The rigidity by the carbon fiber also for long, dramatic doors ease access to the two small seats.

While most hybrids are based on existing vehicles, BMW had the luxury of starting scratch. As with all 50/50-balanced the majority of braking forces at the front axle. So, in the effort to as much energy from braking, it makes sense for BMW to fit the half of the powertrain up front.

The i8 uses a modified version of the electric motor, with a output of 129 hp and 184 lb-ft of torque. fed juice, of course, by those and takes about two hours to from a 240-volt trough. topped off, the i8 will 20 miles of all-electric driving.

Company: 220-Horse Three-Cylinder

The Vision EfficientDynamics concept a three-cylinder turbo-diesel engine, but the i8 use of a gas-fired turbo three-cylinder may turn out to be the best part of the puzzle. It is a version of BMW’s new engine on which we first in April. It displaces just 1.5 features direct injection, a variable camshaft timing, and intake-cam lift.

It makes an 220 hp and 221 lb-ft of torque. Altogether, the powertrain makes 349 hp and 406 lb-ft of That puts this car in company within BMW. M company.

The i8 weighs slightly than a 1-series M. and makes power and torque. BMW says the i8 is to 155 mph and it will accelerate from 0 to 60 mph in than five seconds; more like low fours a quarter-mile time of less 13 seconds. But where the 1M gets, at 26 mpg on the highway, BMW says the ocho return real-world, combined economy near 40 mpg.

One area of concern for twisty-road is its tires. They are narrow, of the variety and will thus in limit grip. We hope an option box for summer tires.

No was made regarding what of transmission will be paired the gas engine, but Bimmer reps it is an automatic and a familiar piece.

Our hunch is that it could be an un familiar six- or seven-speed automatic, although it might be the Cooper’s six-speed slushbox for efficient, low-rpm torque-convertor

A button-activated “Eco Pro” dulls throttle response and the climate-control systems draw on the system. This improves economy and has the potential to stretch the range a bit.

While not has changed about the i8’s a few themes have emerged now it has a sibling in the i3. The laying of light-gray over a black and clear is meant to reference the car’s and Drive components. Many of clear layers, like the half of the swing-wing doors, turn opaque when time comes.

Besides looking flat-out futuristic, BMW i will be marked by a BMW roundel a blue ring around the blue accents on the grilles and sills, and the “stream flow” treatment.

Inside, the i8 concept foregoes gauges in exchange for a more 8.8-inch display screen for road and engine speed, as as battery and fuel levels. In Eco Pro the digital gauges glow in Sport modedetails of which in short supplythey glow A second screen tops the above the center stack to navigation and infotainment functions, and the of the interior is clean, simple, and largely of recycled or sustainable
