Last month MINI announced updates to the entire MINI line-up with more power and more efficiency. We reported the details earlier this year but to recap, here are the numbers with the new engines.

– MINI Cooper: 120 hp (up 2 hp)
– MINI Cooper S: 179 hp (up 7 hp)

The JCW is unchanged thus far but we expect more information later this year.

All of these changes will go into effect with March production in almost every market around the world except for the US. With the mid-life cycle model refresh coming on-line with September production MINI USA has decided to delay the introduction of the updated engines to coincide with the refresh launch. With this change MINI will have a clean differentiation between the 2010 and 2011 models. So for all those on the fence about when and what to get, September production just got a lot more interesting.

For reference, here’s the full rundown on the MC and MCS engine upgrades.

The 2010 Cooper

BMW already had VALVETRONIC in the naturally aspirated Cooper so the extra power would have to be made up with other techniques. Specifically BMW has optimized the ECU and in turn the engine’s output has gone up 2 hp in total. You can read the entire specifications list below in the official PDFs.

The 2010 Cooper S

The 2010 MCS has added a fully variable valve control known in BMW speak as VALVETRONIC. What this does is optimize the engine’s responses and enables a significant reduction in fuel consumption and emissions. It does so by adjusting the lift and opening period of the intake valves to the driver’s power requirements within fractions of a second.

All this adds up to more power but also noticeably more efficiency. Technically the 1.6L turbo is now the world’s most efficient unit in this displacement class. You can see the entire list of specifications in the official PDFs below.
