Mini has confirmed the most powerful diesel model in its line-up to date: the Cooper SD.
Due for launch in the spring, after a public debut at the Geneva motor show, the Cooper SD features a 2.0-litre, common-rail turbodiesel powerplant producing 141bhp and a hefty 225lb ft between 1750rpm and 2700rpm. That’s more than 30lb ft up on the John Cooper Works performance models.
The unit — built on the same architecture as the Mini’s 1.6-litre oil-burner — has an all-aluminium crank case and a variable-geometry turbocharger. The SD spec also includes stop-start, brake energy regeneration and electric power steering in a bid to boost efficiency. It comes with a six-speed manual gearbox as standard.
The set-up will also come on the Clubman, Countryman and Convertible. In the three-door it delivers 0-62mph in 8.1sec and is good for 134mph, but also 65.7mpg and 114g/km of CO2. The Clubman and Convertible hit 62mph in 8.6sec and 8.7sec respectively, and return 64.2mpg and 62.8mpg.
