Built a 1,250-HorsePower Monster : Know How Nissan do It

RealAutoTips. -  Rear-wheel drive is better than front-wheel drive for handling and weight distribution has be a long-held belief by auto engineers when  it comes to maneuvering a 200-mile-per-hour racecar. Notion on its head may turned by Nissan’s new GT-R LM Nismo. In the elite LM P1 prototype class at the 24 Hours of Le Mans World Endurance Championship, It’s the only front-wheel-drive racer that starts June 13, in Le Mans, France.

The GT-R’s twin-turbo V6 engine up front has placed by Nissan engineers to shift the weight there.  Engineers typically distribute weight evenly for balanced handling. But behind the GT-R’s engine sits a kinetic energy recovery system (ERS), which captures energy during braking and stores it for later use. So it is a counterintuitive approach.  For added horsepower and acceleration, most teams in the LM P1 class employ ERS, but Nissan’s team found a clever way to exploit it.

The front brakes work harder because moving the engine forward. To harvest and could boost the car’s chances of winning, it is creates more kinetic energy. When Nissan applies the same technology to increase acceleration and fuel economy in its production vehicles, the biggest payoff could come offtrack.
