MERCEDES-BENZ has launched a super-clean diesel version of the A-class which qualifies for the lowest band for vehicle excise duty.

The A160 CDI uses the same 1.7-litre engine as the A170 CDI but tweaks have enabled carbon dioxide emissions to be reduced to 119g/km, with fuel consumption at 62.8mpg on the combined cycle. At £13,995 on the road, it just undercuts the Audi A2 1.4TDI, and falls into the 18% bracket for benefit-in-kind tax.

Meanwhile, a six-cylinder engine has been fitted to the C-class Sports Coupe for the first time. The C320 SE uses a 3.2-litre V6, developing 218bhp, does the 0-62mph sprint in 7.7 seconds and will be priced at £24,990. Combined fuel consumption is 25.9mpg for the manual (auto: 26.7mph) and carbon dioxide emissions are 262g/km (auto: 254).

Sports packs, costing £630, have been announced for the C-class saloon and estates, with upgraded alloys, lowered suspension and special interior trim. There is also an AMG Sports Package, with AMG body styling and wheels, priced at £2,810.
