                            Nissan's new GT-R LM Nismo - The 1, 250 Horsepower Monster


When it comes to maneuvering a 200-mile-per-hour racecar, auto engineers tend to hew to a long-held belief: Rear-wheel drive is better than front-wheel drive for handling and weight distribution. 

Nissan’s new GT-R LM Nismo may turn that notion on its head. 

It’s the only front-wheel-drive racer in the elite LM P1 prototype class at the 24 Hours of Le Mans World Endurance Championship, which starts June 13, in Le Mans, France.

Nissan engineers placed the GT-R’s twin-turbo V6 engine up front to shift the weight there. It’s a counterintuitive approach: 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. 

Most teams in the LM P1 class employ ERS for added horsepower and acceleration, but Nissan’s team found a clever way to exploit it.

Moving the engine forward makes the front brakes work harder. 

That creates more kinetic energy to harvest and could boost the car’s chances of winning. But the biggest payoff could come offtrack, when Nissan applies the same technology to increase acceleration and fuel economy in its production vehicles.
