New Mini Cooper SD gets 2.0-liter Turbo Diesel with 143HP and up to 65.7 UK MPG

MINI has introduced the most power diesel variant yet in its line-up in the form of the new Cooper SD which is powered by a new 2.0-liter turbocharged four-cylinder oil-burner that makes 143-horses at 4,000 rpm and an impressive 305 Nm (225 lb-ft) of peak torque, available between 1,750 and 2,700 rpm. The Cooper SD trim is offered in the three-door hatch, the Clubman, the Convertible and the Countryman crossover.

The four-pot diesel is loosely based on the 1.6-litre units fitted in the MINI One D and Cooper D models, and is linked to a standard six-speed manual gearbox with a six speed automatic transmission being offered from launch as an option.

To improve fuel economy and reduce CO2 emissions, all Cooper SD models will come fitted as standard with a Brake Energy Regeneration system, Auto Start/Stop function, Shift Point Display, Electric Power Steering and the need-based operation of ancillary components plus a diesel particulate filter and an oxidation catalytic converter.

In terms of performance, the three-door Cooper SD completes the 0-100km/h (62mph) in 8.1 seconds en route to a top speed of 215 km/h (134 mph), while returning an average fuel consumption of 4.3 lt/100km (65.7 mpg UK or 54.7 mpg US) and CO2 emissions of 114 g/km.

The new Cooper SD Clubman reaches 100 km/h (62 mph) from a standstill in 8.6 seconds and also has a top speed of 215 km/h (134 mph). Its average fuel economy is 4.4 lt/100 km (64.2 mpg UK), while CO2 emissions stand at 115 g/km.

The respective numbers for the Cooper SD Convertible are: 8.7 seconds, 210 km/h (130 mph), 4.5lt/100 km (62.8 mpg UK) and 118g/km of CO2.

In the Countryman the new diesel can be teamed up either with front-wheel drive or the all-wheel-drive system MINI ALL4. The FWD Cooper SD Countryman sprints from 0 to 100 km/h (62 mph) in 9.3 seconds, the AWD in 9.4 seconds, on the way to top speeds of 198 and 195 km/h (123/121 mph) respectively. The front-wheel-drive model has fuel economy of 4.6lt/100km, the all-wheel-drive variant achieves 4.9 lt/100 km. CO2 emissions are 122 and 130 g/km respectively.

The new MINI Cooper SD models will get their world premiere at next month's Geneva Salon, with sales set to start across Europe in Spring.
