2015 BMW i8 Concept Release Date - While the i3 and i8 share the LifeDrive architecture philosophy, different cars in execution. wqzxc That's because fully electric i3, while the i8 is a plug-in hybrid. I8 powertrain which is divided between the two axles, with electric motors and direct-drive transmission on the front axle and the gas engine and transaxle in the rear.

Review Concept BMW i8
Interestingly, the battery pack in the i3 and i8 uses a lithium-ion chemistry is different, and unique shape. Large, wqzxc square pancake i3 battery is designed to travel longer distances-in other words, he has a lot of energy and is located under the passenger compartment. In contrast, cell-cell lithium-ion i8 protruding into space Living coupe, where, as in the Chevrolet Volt, which is liquid-cooled and heated battery hump pile of fill that can go wrong for a transmission tunnel. Pak extends i8 is designed to give you a shot of power in short spurts, final spec has not been decided, but it should have a capacity of about 8 kWh.

As with the i3 city car concept that debuted at the same time (you can read about it in full here), the story begins with the i8 LifeDrive architecture called her.wqzxc BMW says that the experience in creating the Mini E and 1-series-based BMW ActiveE showed that adapting cars engineered for internal combustion power electric propulsion results in a lot of excess weight and compromises in packaging. As a result, both i8 and i3 are built using a purpose-built two modules: one for passengers home, dubbed "Life," and one for propulsion and suspension components, so-called. "Hard" Combine them, and you have a car-and-marketing child "LifeDrive" branding.
While most other hybrid vehicles based on existing front-drive, BMW has the luxury of starting from scratch. As with all cars 50/50-balanced, wqzxc the majority of the braking force occurs on the front axle. So, in an effort to cover as much energy from regenerative braking, it makes sense for BMW to fit the electric powertrain front half. I8 using a modified version of the i3 electric motor, with a peak output of 129 hp and 184 lb-ft of torque. This juice eating, of course, by their lithium-ion, and takes about two hours to charge from 240-volt trough. Battery topped off, the i8 will return 20 mile all-electric driving.
So many lightweight materials allow i8 to use, smaller batteries are lighter than required if the car is made of heavy steel. This frees up space in the cabin, wqzxc and more importantly, keeping the curb weight around 3300 pounds slimmer. Stiffness delivered by the carbon fiber also allows for very long, dramatic door that allows access to the two small rear seats.
Like the Porsche 918 supercar, the i8 engine and electric motor can be any power of their own car or they can work together wqzxc for better traction at launch or when powering out of a tight corner. Each axle also contribute to the regenerative power, the home front regenerative braking system, while at the back of the engine has a high-voltage alternator-seems to be about half the size of the inline-three-block to recapture energy.
