|The new Mini One.|
BMW will unveil the new MINI One and MINI Cooper D models at the International Geneva Motor Show on 8 March 2007. The new entry-level One features a more efficient 95 hp 1.4-liter gasoline engine, while the Cooper D boasts performance and fuel efficiency from an all-new 1.6-liter 110 hp turbodiesel powerplant.
The Cooper D promises to be the most fuel-efficient and cleanest MINI yet built. In comparison to the outgoing MINI One diesel’s combined fuel consumption of 4.8 l/100km (49 mpg US), the Cooper D is capable of 4.53 l/100km (52 mpg US), with CO2 emissions of 118 g/km.
MINI One also benefits from a significant improvement in both fuel consumption and emissions over the outgoing model. The One’s new 1.4-liter unit delivers 5.7 l/100km (41.3 mpg US), compared to 6.8 l/100km (35 mpg US) from its predecessor—a 16% reduction in fuel consumption. CO2 emissions are now 138g/km, compared to 164g/km produced by the previous model.
The 1.4-liter four-cylinder engine in the MINI One is derived from the 1.6-liter unit that features in the current Cooper model. Smooth power delivery and maximum efficiency are achieved using fully variable valve control, through a system based on BMW Group’s VALVETRONIC technology.
The lightweight aluminum engine producers maximum output of 95 hp (71 kW) at 6,000 rpm—a 5 hp increase on its predecessor. Peak torque is 140 Nm (103 lb-ft) at 4,000 rpm.
The MINI Cooper D’s new turbocharged diesel engine develops 110 hp (82 kW) at 4,000 rpm. Under normal conditions peak torque of 240 Nm (177 lb-ft) is achieved between 1,750 and 2,000 rpm. An Overboost function gives the Cooper D an additional 20 Nm of torque, meaning the driver will experience 260 Nm at 2,000 rpm. This torque figure is identical to that produced by the new MINI Cooper S.
The turbocharger system features variable turbine geometry, ensuring optimum smoothness, efficiency and response even at low engine speeds.
The injection system uses a common rail diesel technology operating at a maximum pressure of 1,600 bar and a precise multiple-injection process for each operating cycle. Combustion chambers optimized in their shape and dimensions prevent unwanted turbulence and maintain a smooth and consistent combustion process at all times.
The Cooper D features a diesel particulate filter.
Both new models come as standard with a six-speed manual transmission. The MINI One will be available to customers with the option of a six-speed automatic transmission.
