It’s only been a little bit of time since we were introduced to the Mini John Cooper Works Countryman, the most powerful turbocharged production Mini ever made, but Mini has a surprise: its engine will trickle down to all other John Cooper Works models for the 2013 model year.
Presently, most JCW Minis make 208 horsepower and 207 pound-feet of torque from a 1.6-liter, twin-scroll turbocharged four-cylinder engine. The new engine has the same displacement, number of cylinders, turbocharger, and direct injection, but small tweaks will improve the engine’s usability and efficiency.
For starters, the direct-injected engines will get a valve timing system that’s similar to BMW’s Valvetronic system. It also boastslightweight camshafts, reinforced pistons, a strengthened cylinder head, a custom exhaust system, and sodium-filled exhaust valves to cool the charge before entering the turbocharger.
The result is a nearly identical power figure: 208 horsepower and 207 pound-feet. That 207 pound-feet of torque is reached during the Mini’s overboost period, but it has a marginally larger rev window: it produces this torque between 2000 rpm and 5200 rpm, slightly more than the 5100 rpm from before. Mini also promises slightly better fuel economy for the JCW models of up to 0.5 liters per 100km, although it hasn’t released equivalent EPA figures yet.
The other big change for 2013 is the addition of automatic transmissions: following in the footsteps of the Countryman, the other John Cooper Works models will have standard six-speed manual and optional six-speed automatic transmissions. While the JCW Countryman hits 60 mph in 6.6 seconds regardless of transmission, the others take about 0.2 seconds longer to hit 60 with an automatic transmission on board. 0-60 times for the JCW models range from 6.1 seconds (manual transmission JCW Coupe) to 6.8 seconds (automatic JCW Convertible).
With the addition of the Countryman, all six Mini models–Coupe, Roadster, Hardtop, Convertible, Clubman, and Countryman–now have John Cooper Works variants.
