Cadillac CTS-V sets track record
The CTS-V is powered by a 542bhp 6.2-litre V8 petrol engine, and lapped the 13-mile track in 7min 59.32sec, according to the American company.
However, that's still almost 40 seconds short of the outright production car record, set this year by a Nissan GT-R.
The CTS-V is scheduled to go on sale in the UK early next year.
