The EPA delays that MINI USA is dealing with may have roots in the fact that 2015 sees a new version of the Cooper S four cylinder. The B48 has quietly made way for the B46 – a variation of the 2.0L which is a classified as a super ultra-low emissions vehicle by the EPA (SULEV). What does this mean to potential owners? Read on.
For starters the 2015 Cooper S could have slightly better MPG numbers because of this change. But those hoping for more power will have to wait for the 2015 JCW. The B46 is rated at the same 189hp and 207 lb-ft. torque that the B48 had.
The 1.5L three cylinder remains unaltered for the 2015 model year.
