The refreshed 2019 Mercedes-Benz C-Class benefits from safety and technology features that were once exclusive to its bigger, more expensive cousin, the midsized E-Class.

The compact luxury sedan also gets a revised exterior and more power. The new version debuts at the Geneva Motor Show in March. It will be on sale in U.S. this fall. 

The latest model boasts a suite of available semi-autonomous driving features. Equipped with updated cameras and radar, the system uses adaptive cruise control and active lane-keeping assist to keep the vehicle within its lane and moving with traffic. It also can use map information to slow the car when it’s approaching curves.

When CR tested the semi-autonomous features on the 2017 E300, we found that they worked well and were especially helpful on long highway commutes. However, by no means do they make the C-Class a self-driving car.

Keep in mind that drivers should always be engaged and have their hands on the steering wheel; the driver-assist system is always checking for the latter. If the driver is found to be inattentive, the system will issue visual and audible warnings before the vehicle speed reduces and the semi-autonomous features turn off.

Automatic emergency braking comes standard on every version of the 2019 C-Class. 

A new 255-hp, 2.0-liter turbocharged four-cylinder engine replaces the 241-hp turbo four-cylinder we tested. The new engine is mated to a nine-speed automatic transmission.

In our road test of the current C300, we praised the outgoing engine for its “ample” power and combined fuel economy of 26 mpg, so any improvements will be a nice extra.

The C-Class won’t yet feature Mercedes’ new MBUX infotainment system. Instead, options include a 12.3-inch digital instrument cluster and a 10.25-inch screen in the center of the dash. According to Mercedes, Android Auto and Apple CarPlay will be standard.

When CR tested the current E-Class, we found the layers upon layers of menus to be distracting and confusing, and the touch-sensitive controls mounted on the steering wheel were far too easy to brush against and accidentally change.

A Qi-standard wireless phone charging pad is optional, as are new upholstery and interior trim choices.

On the outside, buyers may notice redesigned bumpers and trim. The optional AMG Line cars get a diamond-pattern grille and a new front diffuser, as seen in the included photos. LED headlamps and taillamps are standard. Finally, buyers can choose from new colors, as well as a new 17-inch wheel design.
