Nissan Unveils 88 Pound 400-HP Race Car Engine

Posted by samzenpus on from the packs-a-punch dept.

cartechboy writes "Motorsports used to be about lots of horsepower, torque, and big engines. In recent years there's been a shift to downsizing engines, using less fuel, and even using alternative energy such as clean diesel and hybrid powertrains. Today Nissan unveiled a 400-horsepower 1.5-liter three-cylinder turbocharged engine that weighs only 88 pounds. This engine will be part of the advanced plug-in hybrid drivetrain that will power the ZEOD RC electrified race car that will run in the 2015 LMP1 class during the race season. Nissan says the driver of the ZEOD RC will be able to switch between electric power and gasoline power with the batteries being recharged via regenerative braking. Even more impressive, according to Nissan, for every hour the ZEOD RC races, the car will be able to run one lap of the Le Mans' 8.5-mile Circuit de la Sarthe on electric power alone. If true, that will make it the first race car in history to complete a lap during a formal race with absolutely zero emissions. If this all works, we could be witnessing the future of motorsports unfold before our eyes later this year when the ZEOD RC (video) makes its race debut at this year's Le Mans 24 Hours in June."

    If you're going to build a series hybrid, why bother with pistons and cranks? Just make the turbo bigger and you have... a gas turbine. Use it to drive a big alternator and viola! The turbine can run at constant speed and be optimised for that one speed - the rest of the drive train is purely electrical. Someone should at least test the concept.

    Which was the moot point when the FIA series ended. To much power, too difficult to maintain control. Probably the first time any racing series achieved the upper limit in power.

    I would argue that the 1967 Formula One season was the first time a racing series had cars that were too powerful to control. 400-500bhp V8 and V12 engines attached to four wheels and a gas tank, sitting on old-style treaded tires with no downforce wings. In fact, the two fatalities during this season (including Lorenzo Bandini's horrendous accident at Monaco) forced the FIA to mandate new safety features, such as requiring wings on the cars.
