宝马i8可能会搭载动力更强引擎，最近谍照记者在德国拍到了一辆i8原型车照片。该车采用新的不透明后引擎盖，同时配备突出的散热孔，这表明该车内部配备了不同寻常的一些东西。该车不仅增加了引擎冷却系统，而且还配备了AP Racing制动系统。不难想象，该车功率将超过标准的插电混动版。目前有两种可能性。首先，2018款i8将搭载功率更强劲动力系统，该车将搭载升级版1.5升涡轮增压汽油引擎，电机并配备六速自动变速器。据报道输出功率将达到420马力。另外有传言称，宝马正在开发高性能的i8S，该车很可能搭载320马力2.0升双涡轮四缸或480马力3.0升直列六缸双涡轮引擎以及升级版电机用于驱动前轮。预计该车将在今年亮相以纪念宝马成立100周年。预计未来几个月内会有i8S或新款i8改款车更多信息。

Potential high-performance BMW i8 variant spied with extra cooling vents
The BMW i8 may be in store for a more powerful engine, and these spy photos appear to show a prototype testing in Germany. A new rear engine cover, which is opaque and features prominent cooling vents, is the biggest clue this i8 packs something unusual inside.

Given that the BMW i8 prototype spotted here appears to have not only additional engine cooling but also enlarged AP Racing brakes, it’s not a stretch to imagine it has more horsepower on tap than the standard plug-in hybrid.

There are two possibilities as to what, exactly, this prototype portends. Reports suggest that the 2018 BMW i8 will be refreshed with a stronger powertrain, thanks to upgrades to the 1.5-liter turbocharged gas engine, the electric motors, and the car’s six-speed automatic transmission. That could reportedly boost output to as much as 420 horsepower.

A more interesting rumor says that BMW is planning a performance-focused variant that could be called the i8S. The most recent rumblings said that BMW was planning to use either a 320-hp 2.0-liter biturbo four-cylinder engine or a 480-hp biturbo 3.0-liter inline-six, along with an upgraded electric motor to drive the front wheels. That car was expected to debut this year, to coincide with BMW’s centenary celebrations.

We’ll still have to wait some time to see just how much more performance is being added to the BMW i8. Expect to see either the i8S or the refreshed standard i8 in the coming months.
