迈凯伦近日发布了P1 GTR量产版，该车将在日内瓦车展与工作首次见面。该车重量比P1轻了50公斤，这主要是由于车厂采用了多项轻量化措施，包括赛车规格单体侧窗（驾驶员一侧车窗为“票窗”结构），车顶和引擎室采用碳纤维面板，双排气管采用铬镍铁和钛合金，仅此一项就减重6.5公斤。该车搭载的3.8升V8双涡轮增压引擎也进行了升级，功率达到588千瓦/800马力，搭配一台147千瓦/200马力电机，综合输出功率达到735.5千瓦/1000马力。此外，车身宽度也比P1标准版增加80毫米，高度降低50毫米。迈凯伦为这款车提供了19英寸中央锁止合金轮圈和倍耐力轮胎。车尾的固定尾翼高出车身400毫米，比P1的可调尾翼好高出100毫米，下压力增加10%，P1在时速241公里时下压力达到660公斤。

 

McLaren P1 GTR production version breaks cover

McLaren has taken the wraps off the production-spec P1 GTR prior to a public debut set for early next month in Geneva.

 

The P1 GTR is 50 kg (110 lbs) lighter than its road-going sibling thanks to numerous weight-saving measures such as the motorsport-spec polycarbonate side windows (with a driver’s side sliding “ticket window”), carbon fiber panels in the roof and engine bay. The dual exhaust pipes are made from Inconel and titanium alloy which has helped shave off more than 6.5 kg (14.3 lbs).

 

The V8 3.8-liter twin-turbo engine has also been revised and it now develops 800 HP (588 kW) and works with an uprated electric motor generating 200 HP (147 kW) which allows the McLaren P1 GTR provide a combined output of 1,000 HP (735,5 kW).

 

The track-only P1 GTR is 80mm wider than the standard car and also it sits 50mm lower. McLaren has installed a 19-inch set of center-locking motorsport alloy wheels wrapped around in Pirelli slick tires. The most noticeable change at the back is represented by the massive fixed wing sitting 400mm above the rear bodywork, representing a 100mm increase over the P1’s adjustable wing. Downforce levels have been boosted by 10 percent which has enabled the P1 GTR to generate 660 kg (1,455 lbs) at 150 mph (241 km/h).
