What's New in the 2018 Mercedes-Benz C 300?

A 9-speed automatic transmission replaces the 7-speed unit in last year's C 300 and C 300 4Matic variants, resulting in 0.2 seconds shaved from the sedans' 0-to-60 mph time, which is now 5.8 seconds.

The C 350e plug-in hybrid receives LED headlamps as standard. The C 300 Coupe gets a rearview camera as standard.

A power sunroof is standard for the sedans; extendable sun visors are standard throughout. A smartphone integration package (with Apple CarPlay and Android Auto) is a new option. Mercedes-Benz says its AMG engineers have revised various technical features of the C 43 to improve its driving dynamics and bring them more into line with the higher-level AMG models.

The options structure has also changed. The bundles are now smaller, making it easier for buyers to select their preferred features. See the 2018 Mercedes-Benz C-Class models for sale near you

Which C 300 is the Best?

With several body styles and engine choices, a recommendation for one person would make no sense for another. But you can't go wrong with any of them. We do have a fondness for each of the C 43 variants, however.

2018 Mercedes-Benz C 300 vs the competition

2018 Audi A4 -- One year into a new generation. Polished and packed with tech. The S4 is a credible alternative to the C 43. The new A5/S5 also goes up against the C-Class coupes and cabriolets.

2018 BMW 3 Series -- An unbeatable mix of athleticism and luxury, and it has an adult-size back seat. A new generation is expected for 2019. A buyer might well be torn between an M3 (or M4) and a C 63 sedan or coupe.

2018 Cadillac ATS -- One of the best-handling compact sport sedans.

2018 Lexus IS -- Distinctive styling, smart interior and a generous equipment list.

Used Cadillac CTS -- An excellent luxury sedan and a blast to drive hard. A certified pre-owned (CPO) model enables a step up to the midsize segment without spending more money.
