MX-5 with the heavily modified 2 liters engine. The previous 2.0 engine wasn't that sporty character, it was somewhat "lazy", getting weak over 6000 rpm. In Europe, where both the 1.5 and the 2.0 liters engine is available car magazines has preferred the smaller engine because it was more eager to rev. Mazda has had enough of this, so they heavily modified the 2.0 engine. Now it's more eager to rev, far more alive over 6000 rpm. Power has increased to 181 HP/ 184 PS at 7000 rpm, rev limit is 7500 rpm. Peak torque has increased to 151 lb-ft/ 205 Nm, and Mazda says there is slightly more torque at every rpm compared to the outgoing engine.
And it also passes the newest Euro 6d-TEMP emission test.
