奔驰计划对C级车进行中期改款。虽然新车外观变化很细微，但内部动力系统将获得显著升级。其中美版C级系列将搭载全新2.0升四缸涡轮引擎，某些版本还将搭配48伏电机系统，除了有助于提升动力性，还将降低油耗。而汽油-电动混动版C350e将搭载更大电机以提供更强动力。该车还将配备快充硬件并搭配锂电池组，纯电动续航里程31英里（约合50公里）。中级车型C43不会搭载奔驰新的3.0升直列六缸引擎，仍将继续搭载渐进式升降的3.0升V6引擎，而顶级款C63将搭载AMG调校的4.0升V8引擎。所有引擎都将搭配九速自动变速器，后驱仍为标配，而奔驰的4Matic全驱系统将成为选装件。
Mercedes-Benz C-Class getting major engine overhaul this year?
Mercedes-Benz is preparing to give the C-Class a mid-cycle update. The visual changes will be minor, as they always have been, but the modifications under the sheet metal will be much more significant.
In America, the C-Class line-up will start with a brand-new turbocharged 2.0-liter four-cylinder engine, according to sources who spoke to British magazine Autocar. In some applications, it will be part of a 48-volt electrical system that will provide a small power boost and help the C burn less gasoline.
The gasoline-electric C350e will carry on with a bigger electric motor programmed to provide more power. It will also boast faster charging hardware, and its lithium-ion battery pack will provide up to 31 miles of electric-only driving.
Interestingly, the mid-range C43 won't get Mercedes' new 3.0-liter straight-six engine. It will instead carry on with an evolution of the turbocharged 3.0-liter V6 engine that powers today's model. At the top end of the line-up, the C63 will get a tweaked version of AMG's ubiquitous twin-turbocharged 4.0-liter V8.
All engines will shift through a nine-speed automatic transmission. Rear-wheel drive will come standard, and Mercedes' 4Matic all-wheel drive system will be offered at an extra cost on select models.
