奔驰-AMG最终在法兰克福车展发布了Project ONE，车厂宣称这是最接近F1赛车的街道版跑车。该车采用混动系统，包括一台涡轮增压引擎和四台电机。其中一台电机集成了混动涡轮增压其，最高转速10万转/分，其节气门反应优于自然进气V8引擎，而来自排气系统的冗余能量可用于为车载电池充电。另一台电机通过一个正齿轮直接与1.6升V6引擎连接，可提供161马力功率或作为另一台发电机。两台161马力电机驱动前轮，每台最高转速5万转/分，可收回80%的制动能量。汽油引擎和电机一共可提供1000马力功率，整体热效率超过40%，可媲美最新款丰田普锐斯并超过非混动车平均水平。中置V6引擎受益于气动阀弹簧，转速可达1.1万转/分。AMGPerformance4Matic四驱加上扭矩矢量分配和Speedshift八速变速器让这辆车从静止加速至时速180公里仅需不到6秒，最高时速350公里甚至更高。在纯电动模式下，续航里程为25.7公里。车厂只计划生产几百辆，每辆售价超过200万美元（约合人民币1304万元）。
Mercedes-AMG Project One Bursts Into Frankfurt With 1,000 HP
Mercedes-AMG has finally revealed the Project ONE, billed as the closest street-legal vehicle to a Formula 1 race car.
The Project ONE is equipped with a hybrid powertrain combining the benefits of a turbocharged internal-combustion engine and four electric motors.
One electric motor has been integrated into a hybrid turbocharger, running at up to 100,000 rpm even at low engine revs when there is little exhaust flow. Throttle response is consequently better than a naturally aspirated V8, while surplus energy from exhaust flow can be used to charge the onboard battery.
Another electric motor is linked directly to the 1.6-liter V6 engine via a spur gear, providing 161 horsepower or operating as another generator. Two additional 161-horsepower motors drive the front axle, each operating at up to 50,000 rpm and helping recover 80 percent of braking energy.
The gasoline engine and electric motors together produce 1,000 horsepower. Incredibly, overall thermal efficiency is over 40 percent -- on par with the latest Toyota Prius and far higher than average non-hybrid cars.
The mid-placement V6 benefits from pneumatic valve springs to help reach 11,000 rpm. AMG Performance 4Matic+ torque vectoring and a Speedshift eight-speed transmission can launch the Project ONE to 112 mph in under six seconds, with a top speed of 217 mph or higher. Alternatively, the car can quietly sneak around for 16 miles on electricity alone.
The company only plans to build a few hundred units, each expected to sell for more than $2 million.
