2018款吉普大切诺基Trackhawk即将发布，该车将搭载Hellcat引擎并将于今年四季度在美国上市。这款车搭载一台取自Challenger和Charger SRT Hellcat的6.2升V8 Hellcat机械增压引擎，在那两款车上，其功率达到527千瓦/707马力，扭矩875牛米。不过有传言称，为了能延长其全驱部件寿命，吉普可能会调低引擎功率和扭矩。预计在这台高功率引擎的驱动下，这辆重达2433公斤的大切0-97公里/小时加速时间仅需3.5秒，使之成为史上最快SUV。另外，该车最初四分之一英里（约合400米）加速时间11.6秒，最高时速290公里，最大拖挂能力3266公斤。这款车将提供八速自动变速器，搭配四驱系统和后轮电控限滑差速器。车辆前轮配备400毫米，后轮350毫米Brembo刹车盘，车辆97公里至0制动距离34.7米。在外观上，大切Trackhawk将获得进一步升级，前脸增加散热孔，驾驶员一侧雾灯增加进气口，可将更多冷空气导入引擎。车身同色轮拱下是20英寸轮圈，车尾采用四排气尾管。车厢内的设计以驾驶员为核心，转速表位于仪表群中间位置，集成8.4英寸信息娱乐系统配备了该车独有的性能监控仪表。该车标配纳帕真皮和仿麂皮座椅，黑色或深红色Signature真皮套装。
2018 Jeep Grand Cherokee Trackhawk Has 707 HP Of Purring Hellcat
After building anticipation for the 2018 Jeep Grand Cherokee Trackhawk for over a year, the Hellcat-powered SUV is finally officially here. There’s no chance to drive it yet, but the numbers suggest this machine packs some serious muscle. They arrive at dealers during the fourth quarter of 2017.
To get the biggest question out of the way, the 6.2-liter supercharged Hellcat V8 in the Trackhawk produces 707 horsepower (527 kilowatts) and 645 pound-feet (875 Newton-meters) of torque. For reference, the version in the Challenger and Charger SRT Hellcat models makes 707 hp and 650 lb-ft (881 Nm). There were rumors that engineers might de-tune the engine in the Jeep for the longevity of its all-wheel-drive components.
The powerful engine can accelerate the 5,363-pound (2,433-kilogram) Jeep to 60 miles per hour (97 kilometers per hour) in just 3.5 seconds, which Jeep claims makes the Trackhawk the quickest SUV ever. Jeep further reports that the hotrod Grand Cherokee can run the quarter mile in 11.6 seconds and achieve a top speed of 180 mph (290 kph). Plus, it can tow up to 7,200 pounds (3,266 kilograms).
The Trackhawk is only available with an eight-speed automatic gearbox, which features upgrades for added strength over the version in the Hellcat-power Challenger and Charger. It routes power through an all-wheel-drive system with an electronically controlled limited slip differential for the rear wheels.
A set of 15.75-inch (400 millimeter) Brembo brakes in front and 13.78-inch (350 mm) rotors in the rear let the Trackhawk slow just as well as the SUV accelerates. The company claims that braking to a stop from 60 mph (97 kph) requires just 114 feet.
Aesthetically, the Trackhawk gains some functional upgrades that make the most of its improved mechanical parts. The extra slit in the front fascia aids cooling, and an intake in place of the driver’s side foglight routes cool air to the engine. Body-color flares cover the 20-inch wheels. There’s also a new quad-tip exhaust with a dark finish on the tailpipes.
Inside, there’s a driver-focused cockpit. The tachometer now sits in the center of the instrument panel, and the 8.4-inch infotainment system features Trackhawk-exclusive pages for monitoring performance metrics. Nappa leather seats with suede seats are standard. An available Signature Leather Interior Package covers the whole cabin in black or Dark Ruby Red.
