迈凯轮在古德伍德速度节之前发布了570S Sprint，该车是570S的赛道版车型。该车与迈凯轮运动系列（包括540C、570S和570GT）采用相同碳纤维复合材料车架，3.8升V8双涡轮引擎和七速双离合器变速器。但车厂表示，该车功率和扭矩“进一步优化”，但没有透露具体数据，这台引擎的声浪比运动系列其他车型都更雄浑。该车其他改进主要是提升气动布局，包括车鼻采用新的分流器和鳍翼，固定尾翼，车辆下压力进一步增加。中央锁止镁制轮圈搭配倍耐力赛车轮胎，赛车级别0W-40润滑油，赛车级别气压起重器为选装件。车厢内尽量简化，配备了防滚架和灭火器。驾驶员座椅（乘客座椅为选装件）采用碳纤维椅背，六点安全带。

 

McLaren 570S Sprint track car revealed ahead of Goodwood

Ahead of its public debut at the Goodwood Festival of Speed, McLaren has introduced the new 570S Sprint. As earlier teasers suggested, the Sprint is a track-focused version of theMcLaren 570S.

Because the Sprint wasn’t designed to meet any specific racing series rules, McLaren says it was able to have free rein over the car’s design. It uses the same carbon-fiber composite tub as other McLaren Sports Series models (540C, 570S, 570GT), as well as those cars’ 3.8-liter biturbo V8 engine and seven-speed dual-clutch transmission. But McLaren says horsepower and torque have been “optimized,” though no figures have been revealed, and that the engine is louder than in the other Sport Series cars.

 

Other modifications from a regular McLaren 570S focus on aerodynamics, including a new nose with a functional splitter and dive planes, and a fixed carbon-fiber rear wing, which combine to give the Sprint more downforce than any other Sport Series model. Center-lock magnesium wheels wear Pirelli racing slicks, the engine is filled with race-spec 0W-40 oil, and a race-ready air jack system is offered as an option.

 

Inside, the 570S has been stripped out, and a roll cage and fire extinguisher fitted. The driver’s seat (a passenger seat is optional) has a fixed carbon-fiber back and comes with a six-point harness.
