谍照记者近日拍到了宝马工程师对4系Gran Coupe升级版进行测试的照片。这是宝马首次对4系Gran Coupe升级版进行测试，宝马很快还将对4系轿跑车和敞篷车的升级版进行测试。该车将作为2018款车型上市，而类似的升级以及出现在3系车上。新车外观上的变化包括对前后保险杠进行改款，配备LED前大灯。车厢内增加了新的内饰选择和改款信息娱乐系统。不过该车动力系统没有任何变化，这主要是由于宝马刚刚对2017款车型增加了新的引擎。该引擎配备在新的430i和440i上，这两款车替代了老款的428i和435i。其中430i搭载一台248马力2.0升四缸涡轮引擎，而440i搭载一台320马力3.0升六缸涡轮引擎。除了这两台引擎，消费者还可选择后轮或全轮驱动。2017款4系Gran Coupe在美国市场起价42645美元（约合人民币28万元），预计2018款车型价格也不会有什么变化。新车将于明年初亮相。
2018 BMW 4-Series Gran Coupe spy shots
BMW engineers are out testing an updated version of the svelte BMW 4-Series Gran Coupe.
It’s the first time a car from BMW’s 4-Series range has been spotted in updated form and we should see similarly updated versions of the 4-Series coupe and convertible models start testing soon.
The updates are to be introduced for the 2018 model year and follow similar updates already introduced for the related 3-Series range.
The changes to the styling will consist of visual tweaks to the bumpers and the installation of LED headlights. Inside, look for some new trim options plus revised menus for the infotainment system.
There won’t be any changes to the powertrain lineup as BMW has just added some new engines to the 4-Series range for the 2017 model year. The engines feature in new 430i and 440i models that replace the previous 428i and 435i, respectively.
The 430i has a 248-horsepower turbocharged 2.0-liter 4-cylinder while the 440i has a 320-hp turbocharged 3.0-liter 6-cylinder. In addition to these two powertrains, buyers also have the choice of rear- or all-wheel drive.
The 2017 BMW 4-Series Gran Coupe is priced from $42,645, including destination, and we expect the updated model to be priced similarly.Look for a debut early next year.
