BMW M3 vs Mercedes-AMG C63
The latest versions of the BMW M3 and Mercedes-AMG C63 feature downsized engines yet are more powerful than ever. So, which is the best sports saloon?...
What will they cost?
Cash buyers will find the BMW M3 the cheaper option, with it £1929 less than the Mercedes-AMG C63 after discounts. The M3 will cost slightly more to run over three years, though, eventually setting you back £359 more.
The C63 also proves less expensive if you’re interested in a finance deal; with a down payment of £5000, an annual mileage of 10,000 and a 36-month contract, you’ll pay £830 a month. The M3 will cost a little more than £900 a month, although compensation comes in the form of a lower final payment, should you opt to keep the car at the end of the agreement.
On the off-chance that you might be considering one of these two as your next company car, you’ll find little to choose between them on the tax bill front. The C63 will command a £410 premium in benefit-in-kind tax over the course of three years, but given that both will set you back around £25,000 in total, it’s unlikely to help you decide.
Equipment levels are also similar. Both come with sat-nav, a DAB radio, USB sockets, Bluetooth connectivity, electric heated memory seats, power folding door mirrors and a host of performance modes.
Both cars have similar claimed official fuel economy figures, too, at 34.5mpg for the C63 and 34.0mpg for the M3. In our True MPG test the M3 achieved a respectable 27.6mpg, but we didn’t have the opportunity to test the C63. The Mercedes has the larger fuel tank, however, and so in theory a longer range. Both cars attained the maximum five-star safety rating in Euro NCAP crash testing.
