谍照记者近日拍到了2018款吉普大切诺基，该车搭载了Hellcat引擎。这台6.2升V8机械增压引擎同时还配备在道奇Challenger和Charger SRT Hellcat上，功率达到707马力，扭矩650磅-英尺（约合881牛米）。对于大切而言，搭载这台引擎面临的最大问题之一是该车的全轮驱动系统是否能应付得了Hellcat过于强劲的动率和扭矩。即便可以将引擎功率调低一些，但搭载Hellcat引擎的大切由于配备了全驱系统，牵引力获得提升，其加速性也将超过道奇车型。除了功率和扭矩提升，新款大切的车重还将进一步降低，悬挂也将重新调校以利于提升性能。经过这一番改进，预计该车0-96公里/小时加速时间仅需3.0秒甚至更低。不过，该车售价也将超过8万美元。不过，遗憾的是，这款车可能只生产一辆。而重新设计的新一代大切预计将于2018年发布，该车将不再搭载V8引擎，而是只提供V6涡轮增压引擎。

 

2018 Jeep Grand Cherokee Trackhawk spy shots

Our spy photographers have spotted what’s believed to be a prototype for a Jeep Grand Cherokee equipped with Fiat Chrysler Automobiles awesome Hellcat engine.

 

Yes, we’re talking about the supercharged 6.2-liter V-8 that in the Dodge Challenger and Charger SRT Hellcat models delivers 707 horsepower and 650 pound-feet of torque.

 

One of the biggest challengers for the engineers is getting the Grand Cherokee’s all-wheel-drive system to handle the Hellcat’s grunt. It’s thought that the output might be dialed down a little. However, even with a lower output the Hellcat-powered Grand Cherokee is expected to be quicker off the line than its Dodge counterparts thanks to the extra traction of its all-wheel drive.

 

Along with the extra output, we’re expecting some weight-saving mods and a more performance-oriented tune for the suspension compared to the current Grand Cherokee SRT. The end result could be an SUV that accelerates to 60 mph in 3.0 seconds or less. The expected price tag for all this goodness is $80k.

 

Sadly, the Hellcat-powered Grand Cherokee could be a one and done. A redesigned Grand Cherokee is expected to follow in 2018—the same year we’ve heard FCA will start to phase out V-8s in its performance offerings in favor of force-fed V-6s.
