Ferrari 599 HY-KERS
Ferrari has worked diligently to optimize the benefits of the system to the 599's performance. The entire system weighs a modest 40 kilograms, partially offset by the obviation of the starter motor and conventional battery. Integrated into the seven-speed dual-clutch transmission and mounted below the car's center of gravity, the system returns over 100 horsepower, supplementing the V12 engine under hard acceleration and it can even operate under full electric power when puttering around town.
Called the HY-KERS, what you're looking at is a rolling test bed. It's a hybrid, sure, but if you thought this was a haphazard application of a plug-and-play hybrid system, think again. The HY-KERS incorporates a roadgoing derivative of Ferrari's Kinetic Energy Recovery System – fancy-talk for regenerative braking – from last year's Formula One program.
2011 VW Toureg
This one comes standard with a Torsen limited-slip differential, and then you can order a Terrain Tech Pack that adds the differentials and serious off-road capability that once came standard. That takes fuel economy upward, an boost also helped by the increased curve and lower Cd.
BMW 5 Series ActiveHybrid Concept
The dispersion of BMW's ActiveHybrid – and conjoined word – initiative continues with the 5 Series ActiveHybrid Concept. Billed as a "future-oriented full-hybrid model in the upper midrange segment" it boils down to the turbocharged inline-six you love and along with a 53-horsepower electric motor you will learn to love working through an eight-speed auto 'box for the middle-management set. They'll get 10-percent more distance for the gallon, and a squirt of instant boost thanks to those hard working electrons.
2011 Porsche Cayenne Hybrid and Turbo
Porsche's got a lot on the Cayenne line, and having had a look at the new Hybrid and Turbo variants we don't believe they have anything to worry about. The Hybrid is the first from the automaker, but will be just one of five Cayenne trims on offer, and gets you 23-percent better mileage for what is sure to be a hefty premium. Overall system horsepower is 380 horsepower, yet often times you won't even notice it because you'll be "sailing," which is when the drivetrain is decoupled from the engine and happens at speeds up to 97 mph.
2010 Porsche 911 Turbo S
The Porsche 911 Turbo S isn't new, it's just, well, more. All those options boxes on the Porsche Turbo (and you know how Porsche loves options boxes) don't need to be ticked – Porsche already checked them for you. It's the torque vectoring, seven-speed-DSG-and-dynamic-engine-mount-having, chrono-sport-timing, all-singing, all-dancing adaptive ("bending") headlight wearing wunderkind. Oh, and it gets 24.8 miles per gallon.
