Mercedes-Benz has widened the appeal of its C-class coupés with the introduction of the sub-£20,000 C160.

The car, powered by a 122bhp 1796cc engine, is now the entry level model for the coupé series, which has sold just over 2,500 so far this year, and has an on the road price of £19,495 This makes it £870 less than the larger-engined C180 Kompressor on which it is based, and Mercedes-Benz hopes this price will make it more attractive to the fleet market, as well as remaining popular with private buyers.

It is one of a number of additions the manufacturer has made to its C-class range, which also includes new engines, specifications and transmissions.

A Sport edition, which adds a number of exclusive performance, interior and exterior parts such as lowered suspension, sports seats and AMG bodystyling, is now available for £1,830.

The C230 now boasts a new V6 2496cc engine; the C280 now has a 2996cc V6; the C350, which replaces the C320, has a 3498cc V6, while the C320 CDI is powered by a 2987cc V6 common rail diesel.

Starting prices range from £25,565 for the C230 to £33,250 for the C350, and all models are in the showroom now.

Other changes see Mercedes-Benz reacting to customer demand by creating its first saloon-coupé with diesel power, the CLS320 CDI, powered by the same 224bhp engine as its saloon counterpart. Orders are being taken now, with the first customer deliveries expected to be in the autumn.

Also new is the mid-range SLK 280, which boasts a new 231bhp 2996cc engine and costs from £30,975.
