MINI is introducing a new diesel engine under the Cooper SD badge, which will go on sale in spring 2011, and which will represent the most powerful non petrol version available to customers.
The MINI Cooper SD is represented by a 2.0-litre 4-cylinder engine producing 143 HP (105 kW) @ 4,000 rpm and 305 Nm of torque (225 lb-ft) between 1,750 and 2,700 rpm, and is available for the hatchback and the convertible, the Clubman and the Countryman.
At this power level the 3-door version MINI Cooper SD accelerates from 0 to 100 Km/h in 8.1 seconds, and is able to reach a maximum speed of 215 Km/h (134 mph). Consumption and emission levels are very low thanks to a series of standard features like Brake Energy Regeneration,
Auto Start/Stop technology and Shift Point Display plus the diesel
particulate filter and an oxidation catalytic convert
This means that the MINI Cooper SD covers 100 Km on just 4.3-litres of fuel (65.7 mpg / UK rating) while its CO2 levels are 114 grams per Km.
The MINI Cooper SD Clubman hit 100 Km/h from a standstill in 8.6 seconds, consumes 4.4-litres of fuel per 100 Km (64.2 mpg / UK rating) and emits 115 grams of CO2 per Km.
Moving on to the MINI Cooper SD Convertible, its performance figures indicate that accelerating from nought to 100 Km/h requires 8.7 seconds, top speed is 210 Km/h (130 mph) and consumption and emissions are 4.5-litres/100 Km and 118 g/Km of CO2.
Finally in the MINI Cooper SD Countryman which can be order with either front-wheel-drive or all-wheel-drive (ALL4) accelerating from 0 to 100 Km/h takes 9.3 / 9.4 seconds while consumption figures are 4.6 / 4.9-litres per 100 Km. CO2 emissions are 122 on the FWD and 130 grams per Km on the ALL4. 
MINI press release :
Munich. Just a few months after the market launch of the new MINI
family and the MINI Countryman, the start of 2011 has brought another
wave of driving fun and individuality in the premium brand’s
hallmark style. The MINI Cooper SD, due for launch in spring
2011, will be the most powerful diesel variant yet in the MINI
line-up. The new 2.0-litre engine developing 105 kW/143 hp
– available for the MINI, MINI Clubman, MINI Convertible and
MINI Countryman – will drum up even more power yet burn
extremely small amounts of fuel. Motor sport enthusiasts will welcome
the new John Cooper Works Pack option also on offer for the MINI and
MINI Convertible.
Furthermore, the customary selection of personalisation options
available for drivers to configure their MINI in their own image has
taken on even greater proportions. The newly developed MINI Yours
product range offers a host of extremely attractive customisation
options. The first ambassador of the exclusive and innovative MINI
Yours style will be the MINI Clubman Hampton special edition.
MINI Cooper SD: Impressive on the power, frugal at the pumps.
The new MINI Cooper SD slots into the range above the MINI
One D with 66 kW/90 hp and MINI Cooper D
developing 82 kW/112 hp as the most powerful diesel MINI.
Its 2.0-litre four-cylinder turbodiesel unit produces maximum output
of 105 kW/143 hp at 4,000 rpm. A stand-out
characteristic of the new diesel is its mighty pulling power, which
remains on tap even under heavy loads; maximum torque of
305 Newton metres (225 lb-ft) is available between 1,750 and
2,700 rpm. Add this to the excellent balance between output and
fuel consumption familiar from the other models in the MINI family
plus extraordinary power development for a four-cylinder engine, and
the MINI Cooper SD has all the tools the sporty driver could ever need.
In its basic construction, the new 2.0-litre diesel fits the same
template as the 1.6-litre units fitted in the MINI One D and MINI
Cooper D. Its all-aluminium crankcase helps to keep the weight of
the engine as low as possible, while the turbocharger with variable
intake geometry develops the right level of power at all engine
speeds. The engine in the MINI Cooper SD has a model-specific and
extremely powerful turbocharger controlled by the engine management
system, while common-rail direct injection with solenoid-valve
injectors positioned centrally in the cylinder head ensure that the
fuel is fed in extremely precisely and efficiently. The injection
system works with maximum pressure of 1,600 bar and ensures
optimum mixture preparation in the combustion chamber.
The new MINI Cooper SD is also fitted as standard with an
extensive range of MINIMALISM technology. In addition to the
engine’s efficiency, features such as Brake Energy Regeneration,
the Auto Start/Stop function, Shift Point Display, Electric Power
Steering and the need-based operation of ancillary components help to
produce outstanding fuel economy for this output class.
To ensure that its emissions are as clean as possible, the MINI
Cooper SD is fitted with a diesel particulate filter and an
oxidation catalytic converter. No extra injections of fuel are
required to clean the particulate filter. And, as with all current
MINI models, the new diesel variants meet the EU5 exhaust emissions
standard. Comfort levels on the move, meanwhile, are aided by the
four-cylinder engine’s low vibrations and harmonious acoustic
properties; here, the particularly sonorous soundtrack of the MINI
Cooper SD unit when pushing on through higher revs lifts it above
its two diesel stablemates.
The 2.0-litre powerplant demonstrates its sporting credentials in the
MINI Cooper SD with acceleration of 0 to 100 km/h (62 mph)
in 8.1 seconds and a top speed of 215 km/h (134 mph). This
outstanding level of efficiency is reflected in average fuel
consumption in the EU test cycle of 4.3 litres per 100 kilometres
(65.7 mpg imp) and CO2 emissions of 114 grams per kilometre. The
new MINI 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). The average fuel economy of the MINI
Cooper SD Clubman is 4.4 litres per 100 km (64.2 mpg imp), while
CO2 emissions stand at 115 g/km. The MINI Cooper SD
Convertible, meanwhile, highlights its sporting potential with a 0 to
100 km/h (62 mph) time of 8.7 seconds and a maximum speed of
210 km/h (130 mph). Its extra dose of driving fun combines with
average fuel consumption of 4.5 litres per 100 km (62.8 mpg imp)
and CO2 emissions of 118 g/km.
In the MINI Countryman this extra-sporty diesel engine teams up with
either front-wheel drive or the all-wheel-drive system MINI ALL4. The
MINI Cooper SD Countryman sprints from 0 to 100 km/h (62 mph) in 9.3
seconds, the MINI Cooper SD Countryman ALL4 in 9.4 seconds,
on the way to top speeds of 198 and 195 km/h (123/121 mph)
respectively. The front-wheel-drive MINI Cooper SD Countryman has fuel
economy of 4.6 litres per 100 km, the all-wheel-drive variant
achieves 4.9 litres per 100 km. CO2 emissions are 122 and
130 grams per kilometre respectively.
The models fitted with the new diesel powerplant come as standard
with a six-speed manual gearbox, whose ratios are tuned carefully to
the engine’s performance characteristics to enable powerful and
silky smooth acceleration. A ready-to-drive weight of
44.8 kilograms (98.7 lb) makes this the lightest gearbox of its
kind. Added to which, it sets a new benchmark in the MINI segment with
its short shift travel and impressively precise action. A six-speed
automatic gearbox will also be available from launch as an option. Its
exceptionally short shift times and direct “target gear”
finding capability on downshifts also allow the automatic to enhance
the sporting character of the MINI Cooper SD. The six-speed automatic
will also be available for the MINI Cooper D, MINI Cooper D
Clubman, MINI Cooper D Convertible and MINI Cooper D
Countryman from spring 2011. In the interests of delivering the
optimum combination of engine and gearbox, these models will also be
powered by a 2.0-litre diesel unit. This variant matches the output
and torque of the 1.6-litre engine in the model variants with manual gearbox.
The MINI Cooper SD also uses model-specific design features to
show off its sporting credentials. The most powerful diesel model in
the range stands out – like the flagship petrol model, the MINI
Cooper S – with its extra-large air intake in the front
apron and an air scoop on the bonnet. Like the MINI Cooper S, it
also displays its model identity in its side indicator surrounds (in
its case with “SD” lettering) and has twin tailpipes
positioned in the centre of the rear apron. The MINI Cooper SD,
MINI Cooper SD Clubman and MINI Cooper SD Countryman also
come with an eye-catching roof spoiler.
