Infiniti Emerg-E

Automakers are having a tough time figuring out this whole hybrid and electric game. Just about every automaker has a hybrid, but few sell well. Likewise, most brands have an electric vehicle or an extended-range electric vehicle (EREV) in the works, but initial sales are limited at best, and there is no assurance that Americans will buy a car they have to plug in every night. The one true success has been the Toyota Prius, but even its sales are down. At the 2012 Geneva Motor Show, several automakers showed hybrids and EREVS that aim for a more affluent clientele, one that can afford to help pay for this burgeoning and much-needed technology. They are sportier, more luxurious and sexier than ever before.

2013 BMW ActiveHybrid 3

BMW ActiveHybrid 3

BMW has dabbled with hybrids in the past, but they've typically been unimpressive, mild hybrid systems. But the 2013 BMW ActiveHybrid 3 promises to be different. This newly developed hybrid system, which will also appear in the ActiveHybrid 5, features a 54-horsepower electric motor paired with a 3.0-liter inline 6-cylinder engine. Total output: 340 horsepower. The system can run on electric power alone up to 37 mph, and BMW estimates a fuel savings of 12 percent over the standard 3-Series. A lithium-ion battery is packaged under the trunk floor so it doesn't intrude on cargo space. Pricing will be available when the BMW ActiveHybrid 3 goes on sale this fall.

Hyundai i-oniq concept

The Hyundai i-oniq extended-range electric vehicle concept could be a glimpse into the brand's future in more ways than one. Hyundai says it features the next expression of its Fluidic Sculpture design language, but more importantly it is powered by a high-tech powertrain along the lines of the Chevrolet Volt. A 1.0-liter 3-cylinder engine extends the 109-horsepower electric motor's range; it acts like a generator, just like the Volt's engine. Hyundai says this sporty hatchback can travel 74 miles on electricity and 435 miles total when the gas engine kicks in. The i-oniq is about as big as a Ford Focus, and its rear seat is designed as a "cozy lounge area." Expect a toned-down version of this design to appear on future Hyundais, with some form of this powertrain as well.

Infiniti Emerg-E Concept

Infiniti Emerg-E

This is one of the hottest cars at the show, period. Infiniti is looking at building a halo car and might team with Lotus to make it an extended-range electric vehicle that can rocket from zero to 60 mph in a tidy four seconds. The Emerg-E Concept is powered by two 150-kilowatt electric motors, one at each rear wheel, that can deliver bursts of 402 horsepower for up to 30 seconds. This slick 2-seater is capable of 30 miles of electric driving, and the range-extending 1.2-liter 3-cylinder engine allows for 300 miles of total range. For weight savings and balance, the powertrain is mounted midship, the chassis is aluminum, and the body panels are carbon-fiber. The Emerg-E may never be produced, but an Infiniti halo car is likely and an EREV is, too.

2013 Lexus RX 450h

Lexus is giving its RX lineup a facelift for 2013, including the hybrid RX 450h. This luxury hybrid gets a little more aggressive and sportier thanks to the adoption of the prominent Lexus spindle grille and the addition of a Sport mode for the hybrid system. Sport mode sharpens throttle and steering response and allows more play in the traction- and stability-control systems. Inside, this crossover gets a more comfortable steering wheel, a new Hybrid System Indicator gauge and the next generation of Lexus' Remote Touch, which we think is harder to use than the first gen. Pricing should stay in the $45,000 range when the RX450h goes on sale later this year.

Volkswagen Cross Coupe

Volkswagen Cross Coupe

Volkswagen showed this sporty crossover in Tokyo last year with a gasoline plug-in hybrid powertrain. Now it features a more efficient and more powerful diesel engine. Like the gas version, the diesel Cross Coupe has an electric motor up front that makes 133 lb-ft of torque and another in the rear with 199 lb-ft of twist. The 2.0-liter turbodiesel engine puts out 295 lb-ft of torque for a total of 516 lb-ft. That translates into a sprightly zero-to-60-mph romp of 6.5 seconds. The vehicle can run on electric power alone, at up to 75 mph, for 28 miles. VW isn't quoting total range, but it should be more than 500 miles. We expect the Cross Coupe to be built, but when and how much it will cost is still a mystery.
