Audi has announced that the second generation Audi R8 will spawn two more models, first being the all-electric R8 e-tron and second being the R8 LMS race car.
2015 Audi R8 e-tron
The R8 e-tron is powered by a large T-shaped battery which is integrated into the centre tunnel, behind the occupant cell. The battery is positioned in such a way so as to achieve a low centre of gravity for supporting the vehicle dynamics. The 92 kWh lithium-ion battery can be fully charged within less than two hours using the Combined Charging System (CCS) on board which allows charging with alternating and direct current. An energy density of 154 Wh/kg gives the all-electric vehicle a driving range of 450 km.
Combined, the two electric motors develop 381 hp and 820 Nm of torque. With this substantial power output, the R8 e-tron can reach 0-100 km/h in 3.9 seconds and go further to hit a top speed of 210 km/h (electronically-limited) or 250 km/h.
The R8 e-tron will be available for order sometime this year.
2015 Audi R8 LMS
The all-new R8 will also form basis for the second-generation R8 LMS race car. Like that of the standard R8, around 50% parts of the all-new R8 LMS are also borrowed from its predecessor. The 2015 R8 LMS is a rear-wheel drive GT3 race car.
The new-generation R8 LMS is based on a selectively reinforced multimaterial ASF. Its exterior shell is built essentially of carbon fibre reinforced plastics (CFRP). The cabin does feature a safety cage. Yet to be approved, the race car’s weight is currently measured to be 1,225 kg.
The R8 LMS is powered by the same 5.2-litre FSI V10 engine that powers the standard version. The engine produces around 430 kW (approximately 585 hp). Final power output will depend on the applicable regulations and the restrictor required.
The 2015 Audi R8 LMS will be tested by the works team at international long-distance and sprint races, and will be available to customers as part of the Audi driving experience this year. Sales of the new-generation R8 LMS to customer teams around the world will begin with the 2016 season.
