The Porsche 919 Hybrid LMP1 Le Mans prototype made its premiere at the Geneva Motor Show. The hybrid prototype will be joined by the Porsche 911 RSR at the Porsche exhibition in Geneva as well as at all eight races of the World Endurance Championship (WEC), the season highlight of which will be the 24 hours of Le Mans.
Porsche 919 Hybrid development began in the middle of 2011 on a blank sheet of paper. With a 16-year absence from the LMP1 class, Porsche engineers have had to develop the racecar without the same experience of their competitors. However, the experience acquired in racing the 911 GT3 R Hybrid (earlier post) and production of the 918 Spyder plug-in hybrid (earlier post) has directly translated to the 919 Hybrid.

Renault’s Energy F1-2014 hybrid Power Unit (earlier post), designed and developed for the FIA Formula One World Championship this year, is ready for the track; the 2014 season kicks off in Australia on 16 March. New FIA regulations are driving energy efficiency levels higher this year, with two types of energy propelling the cars. The internal combustion engine will produce power through consumption of traditional carbon-based fuel, while electrical energy will be harvested from both exhaust and braking by two discrete motor generator units. Teams and drivers will balance the use of the two types of energy throughout the race.
This year, the power unit is divided into six separate elements: Engine (ICE); Motor generator unit-kinetic (MGU-K); Motor generator unit-heat (MGU-H); Energy store (ES); Turbocharger (TC); and Control electronics (CE). The combination of the 1.6-liter turbocharged direct injection V6 engine (maximum speed of 15,000 rpm) with the two motor generator units and battery energy store delivers combined maximum power output of 760 bhp (567 kW), on a par with the previous V8 generation.

Audi has released initial details on its new 2014-generation Audi R18 e-tron quattro LMP1 Le Mans prototype racer. Although the new diesel hybrid sports car appears like a continuous further development of the World Championship winning car and Le Mans winner of the past two years, due to the new LMP1 regulations that will come into effect in 2014, Audi Sport redeveloped every component.
In the new Technical Regulations, a large number of principal definitions, which concern the powertrain, body dimensions, safety and aerodynamics, were re-determined. With the new R18, Audi Sport has opted for a similar concept as in the past—albeit with new detailed solutions and an additional hybrid system. Powertrain elements include:

Drayson Racing Technologies will make an attempt for the FIA World Electric Land Speed Record in the sub-1000kg class on 25 June at RAF Elvington in Yorkshire using a modified version of the Lola-Drayson B12/69EV electric Le Mans Prototype (earlier post). Lord Drayson, CEO and co-founder of Drayson Racing Technologies (as well as former UK science minister) will drive the EV flat-out along Elvington’s 1.86-mile runway.
Lord Drayson will aim to better the current record of 175 mph (282 km/h) set by Battery Box General Electric in the United States and which has stood since 1974. This record has held firm for nearly 40 years due to the technical challenge of running an electric vehicle consistently and reliably at such speeds when weighing less than 1000 kg, Drayson said.

Renault engineers have built an “F1” concept version of the Twizy EV featuring a Kinetic Energy Recovery System (KERS) based on the solution used by Renault-powered Formula 1 race cars.
Twizy Renault Sport F1 is consequently equipped with two electric motors—i.e. the original motor (17 hp/13 kW) onto which the F1-style KERS with its own motor has been grafted. When the KERS is activated, Twizy Renault Sport F1’s power output climbs instantly by a factor of six, from 17 to 97 horsepower (72 kW). This boost is available for approximately 14 seconds, just as it is in the case of a Formula 1 car. Thanks to this additional power, the concept car is capable of accelerating from standstill to 100 km/h in the same time as Mégane R.S.
