BMW will finally bring at the 2013 Frankfurt Motor Show (Internationale Automobil-Ausstellung, Frankfurt am Main, Germany, 10-22 September) its new hybrid supercar version named BMW i8. The new hybrid supercar has a turbocharged three-cylinder engine and promises a mixed fuel consumption of 2.5 liters/100 km (113 mpg Imp. / 94 mpg US).
BMW i8, the new Bavarian hybrid supercar, will be officially presented at Frankfurt Motor Show 2013, accompanied by the production version of BMW i3. Like its city destined brother, BMW i8 will be presented as the series version, and will be offered on sale over the next year. Besides the hybrid powertrain and the innovative bodywork, i8 brings the first three-cylinder turbocharged engine in the BMW range.
BMW i8 – Engine & Design & Price
The 1.5-liter engine delivers 231 horsepower. The combustion unit is supplemented by an 131 horsepower electric motor. The two engines can work independently or together, can deliver a total of 362 horsepower and 570 Nm of torque (420 lb-ft) in the configuration designed to obtain maximum performance.
The hybrid BMW i3 can accelerate from 0 to 100 km/h (62 mph) in less than 4.5 seconds, the maximum speed being electronically limited at 250 km/h (155 mph). In 100% electric mode, the model can reach 120 km/h (75 mph).
The new BMW i8 has a lithium-ion battery that can be charged from a standard socket in three and a half hours. The autonomy in 100% electric mode is 35 kilometers (22 miles). A special charger applied to a 220V outlet reduced the load time to an hour and a half. However, with the internal combustion engine, the autonomy of i8 can go up to 500 kilometers (310 miles) in Comfort mode. If the driver activates the Eco Pro mode, autonomy of the hybrid supercar increase by 20 percent compared to the previous mentioned values.
BMW i8 has a six-speed automatic transmission that connects the internal combustion engine to the rear axle, while the front wheels engaging the electric motor with a special automatic transmission, which operates in two stages. Together, the two engines can operate in different driving modes, offering either front-wheel drive and 100% electric driving or all-wheel drive in hybrid mode.
The 2 +2 sports car weighs just 1,490 kilogram (3,285 lbs), thanks to Life Module configuration, developed specifically for this bodywork, several parts of the chassis and the body being made of CFRP, aluminum and magnesium. Vertical opening doors will remain a standard element of the model and are possible due to the reinforcement applied to the body using carbon fiber panels. These changes were necessary to obtain a mass as low as necessary to compensate for the presence of the hybrid system.
The BMW i8 bodywork has a length of 4,689 mm (15.4 ft) and a width of 1,942 mm (6.3 ft). As in the case of the concept, the model has a wheelbase of 2,800 mm (9.2 ft) and a reduced height of 1,293 mm (4.2 ft). The drag coefficient is a exemplary, just 0.26 . Moreover, the carbon fiber bodywork of the new BMW i8 has a 50:50 weight distribution between the axles and a gravity center positioned very low.
In standard, the hybrid supercar has DSC, Brake Assist, a number of special features for braking and a Start Assistance. The Stability Control System also has a setting that allows the partial decoupling of the system, allowing the rear wheel to slide in some cases.
BMW i8 price is not yet finale, but according to a senior BMW figure, will be around EUR 125,000 (~ £ 105,000 / $ 165,000) when will go on sale in 2014.
BMW i8 fulfills the promise of The Ultimate Driving MachineTM in a revolutionary and mold-breaking form. This is reflected in a highly emotive design, dynamic sports car performance, and fuel efficiency and emissions figures worthy of a small car. Pairing an exceptionally lightweight, aerodynamically optimized body with cutting-edge BMW eDrive technology, a compact, turbocharged 1.5-liter BMW TwinPower Turbo gasoline engine and intelligent energy management, the BMW i8 marks the next stage in the evolution of the Efficient Dynamics strategy. Its revolutionary approach achieves an unprecedented balance between performance and fuel efficiency. Thanks to its carbon-fiber-reinforced plastic (CFRP) passenger cell, the BMW i8 sets new standards for a plug-in hybrid vehicle in terms of low weight. It can operate solely on electric power, which means no tailpipe emissions, and offers the dynamic performance of a sports car.
The plug-in hybrid system of the BMW i8, which comprises a BMW TwinPower Turbo engine combined with BMW eDrive technology, offers the best of both worlds: excellent potential for improved efficiency and exciting, sporty driving characteristics. The BMW Group has developed not only the internal combustion engine and electric motor in-house but also the power electronics and the battery. This ensures that all these components offer high product and quality standards, based on the outstanding capabilities of the BMW Group in the field of powertrain research and development.
