Mini will launch the Cooper SD this spring. The most powerful diesel model in its line-up to date, the Cooper SD made its public debut at the Geneva motor show.
This engine features a 2.0-litre, common-rail turbodiesel powerplant, which delivers 141bhp and a 225lb ft between 1750rpm and 2700rpm. This is higher by 30lb ft compared to the John Cooper Works performance models.
Built on the same architecture as the Mini’s 1.6-litre oil-burner, this unit has an all-aluminum crank case and a variable-geometry turbocharger. Mini also revealed that the SD spec includes stop-start, brake energy regeneration and electric power steering in order to improve efficiency. A six-speed manual gearbox is offered as standard.
This set-up can also be seen on the Clubman, Countryman and Convertible. The three-door variant is able to accelerate from a standstill to 62mph in 8.1sec and it can reach a maximum speed of 134mph. It also offers a fuel rating of 65.7mpg and 114g/km of CO2 emissions.
The Clubman can sprint from 0-62mph in 8.6sec and can return 64.2mpg. Meanwhile, the Convertible’s 0-62mph acceleration time is 8.7sec and it has a fuel rating of 62.8mpg.
The Countryman SD is available in two and four-wheel drive forms. The front-drive variant is quicker by 0.1sec when accelerating to 62mph (when compared to the All4 version at 9.3sec).
The front-drive variant is also more efficient at 61.4mpg versus 57.6mpg of the All4. The exterior of the SD models is similar to that Cooper S. It features the same larger front air intake and a bonnet scoop.
A roof spoiler is offered on all variants but the Convertible. Mini has plans to make a six-speed automatic gearbox optional on the SD. Mini also wants to use this transmission on regular D models. It’s interesting that the D autos will be powered by the 2.0-litre motor, detuned to go with the power and torque of the 1.6.
