As emissions standards tighten, you might think International Engine of the Year would go to a clever compact powertrain or an engine that mixes miserly fuel consumption with punchy performance. Turns out the judges weren't thinking that way, and handed this year's award to the a Ferrari V8 instead.

Despite the ever-tightening noose designed to legally choke emissions, KTM goes against the Euro 4 flow by announcing a new two-stroke platform for its Enduro motorcycles. And it could well prove to be a game changer.
-
Toyota has unveiled new engines based on its Toyota New Global Architecture (TNGA), to be used in both standard gasoline and hybrid vehicles. The company says that the recently-developed, more efficient engines will begin rolling out in 2017.

This refreshingly simple forced induction system for motorcycles won't give you the huge power output of a turbo system - but it can give you a boost of up to 0.6 bar and some 15-25 percent more power, torque and efficiency at "about a tenth" the price of a turbo setup.

Harley-Davidson has announced its ninth generation American V-Twin engine. Featuring more power, more torque, less vibrations, better heat dispersion and an enhanced exhaust note, meet the Milwaukee Eight.
-
Forget variable length intakes and variable valve timing, Infiniti is going all the way and introducing variable cylinder compression ratios. The new VC-T turbo engine automatically adjusts between a high-powered 8:1 and a hugely efficient 14:1 ratio as you drive.
