Until August olly slim protein smoothie review This turbocharged petrol engine develops 241bhp and 258lb ft and delivers 143mph, 0-62mph in 6.4sec, 45.6mpg and 144g/km. It feels lively, as it should with all that horsepower, and has a pleasing - if slightly harsh - mechanical note, although not as nice as the mellifluous Swedish-designed, Bridgend-built compact six-cylinder engine it replaces. That said, this T5 engine isn't that far off the pace of engines such as the four-cylinder turbocharged unit being fitted to BMW's fleet. Initially, this engine won't be available in the UK.
