The new MINI hatch line-up will soon be complete, when the new MINI One and MINI Cooper D models are unveiled to the public at the International Geneva Motor Show on 8 March 2007. The entry-level One features a perky 95hp 1.4-liter petrol engine, while the Cooper D boasts performance and fuel efficiency from an all-new 1.6-liter 110hp turbodiesel powerplant.

A Cooper-badged MINI diesel hints at the sporty nature of the new model. MINI fans will be equally excited at the prospect of the Cooper D promising to be the most fuel-efficient and cleanest MINI ever built. In comparison to the outgoing MINI One D's combined fuel consumption of 58.9mpg, the Cooper D is capable of 64.2mpg. A CO2 figure of just 118 g/km puts the car in tax band B.

MINI One also benefits from a significant improvement in both fuel consumption and emissions over the outgoing model. 49.6mpg is achievable from the One's new 1.4-liter unit, compared to 41.5mpg from its predecessor. CO2 emissions are now 138g/km, against 164g/km produced by the previous model.

The MINI One will cost 11,595 on the road, and the MINI Cooper D will be 14,190. Both models will be on sale from April 2007.

Both models feature the new body shape already seen on the recently launched MINI Cooper and Cooper S models. Interior quality enhancements and unique design features remain key characteristics of the One and Cooper D. However, several individual highlights set the cars apart.

MINI One: Technology highlights

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 unique VALVETRONIC technology.

Maximum output of 95hp at 6,000rpm is produced by the compact engine, which is constructed from lightweight aluminum. The 5hp power increase on its predecessor leads to a peak torque figure of 140Nm at 4,000rpm.

The innovative powertrain is key to the MINI One's ability to ensure a grin-inducing driving experience, yet offers the driver outstanding fuel economy and low emissions. A 0-62mph time of 10.9 seconds and top speed of 115mph are complemented by an average fuel consumption figure of 49.6mpg an efficiency increase of 15 per cent compared to the outgoing model.

MINI Cooper D: Technology highlights

The MINI Cooper D's brand new turbocharged diesel engine develops 110hp at 4,000rpm. Under normal conditions peak torque of 240Nm is achieved between 1,750 and 2,000rpm. Deploying the engine's Overboost function gives the Cooper D an additional 20Nm of torque, meaning the driver will experience 260Nm at 2,000rpm. MINI enthusiasts will recognize 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.

Second-generation common rail diesel technology operating at a maximum pressure of 1,600 bar is key to the new diesel engine's combustion process. Additionally, refinement is achieved using a precise multiple-injection process for each operating cycle. The combustion chambers have been optimized in their shape and dimensions to prevent unwanted turbulence and maintain a smooth and consistent combustion process at all times.

A diesel particulate filter almost eliminates diesel exhaust emissions and helps to make the MINI diesel engine one of the most environmentally friendly engines in its class.
