现行版宝马1系是在三年前上市的，因此现在宝马正在开发其改款车型。最近谍照记者拍到了新款M135i原型车，该车采用了新的前保险杠，改款格栅和更小的前大灯。车位的改变似乎不明显，但从遮盖的部位看，后保险杠将进行改款。新车动力系统选择与人们预计的一样，其中M135i将搭载一台3.0升TwinPower Turbo直列六缸引擎，功率240千瓦/326马力，扭矩450牛米。宝马将在今年底或明年初发布2015款1系改款车。
2015 BMW 1-Series spied showing modest changes
The BMW 1-Series was introduced three years ago so it comes as little surprise that the company is working on a minor facelift for their entry-level hatchback.
This particular prototype is the new M135i and it appears to feature a new front bumper, a revised grille and smaller headlights. The styling changes are less notable out back but the camouflage suggests there will be a new rear bumper.
Engine options will likely include the usual suspects, so expect the M135i to feature a 3.0-liter TwinPower Turbo inline-six that cranks out 326 HP (240 kW) and 450 Nm (322 lb-ft) of torque.
The 1-Series facelift could be introduced later this year or early next year, so expect to learn more in the coming months.
