Mercedes SLS Cabrio spied

Soaking up the summer sun, Mercedes' SLS cabrio has broken cover and we have the best pictures yet of the soft-top stunner out on test.

Using the same 563bhp 6.2-litre V8 AMG engine as the coupe, the soft-top will have blistering pace, reaching 60mph in less than 4 seconds on its way to a top speed just shy of 200mph.

On close inspection, we can also see the convertible in the picture has opted for conventional doors unlike the retro-inspired vertical-opening Gullwing doors found on the coupe.

Scheduled to make its debut at next months Frankfurt Motor Show, the soft-top supercar is expected to cost an eye-watering £175,000, when it goes on sale next year.
