The opening price is for the C200 petrol in entry-level SE spec. It gains a new EQ Boost mild hybrid system that uses 48-volt electrical architecture with a belt-driven starter/generator to provide additional torque (read more on powertrains below).
There is also a C220d diesel that starts at £35,690, while the hot six-cylinder-powered AMG C43 tops the three-engine launch range and starts from £49,675.
Both saloon and estate versions are offered, while above SE, Sport and AMG Line trims are offered.
The engine range will be bolstered later this year with a lower-priced entry model and further electrified EQ models. These will be full plug-in hybrids, in the form of the C300e petrol, as well as a four-cylinder diesel hybrid called the C300de.
The new EQ Power system increases the output of the electric motor by 40bhp over that used by the existing four-year-old 300h to 120bhp.
