Already revealed at the recent Detroit Auto Show, Volkswagen will soon hit the market with the Jetta Hybrid vehicle which was spotted being tested at -20°C (-4°F) recently.

Equipped with a battery big enough to move the gas-electric vehicle up to speeds of 70 km/h (43 mph) using nothing but electrons, the new Volkswagen Jetty Hybrid boasts a combined estimated fuel efficiency rating of 45 mpg US (5.2 L/100km; 54.0 mpg UK). If you're concerned about performance, the Jetta Hybrid achieves a class-leading 0-100 km/h time of 9.0 seconds.

Of course, with only 1.1 kilowatt hour in the battery pack, you won't get very far on battery power alone (just 2 kilometers) not to mention all of those electrons come from energy that was originally gasoline since this is not a plug-in hybrid. However, it's still enough of an electric powertrain for VW to call the Jetta Hybrid the "most fuel-efficient Jetta in the lineup."

The hybrid pairs up a four-cylinder 1.4-liter turbocharged gasoline engine producing 150 hp (112 kW / 152 PS) and 184 lb-ft (249 Nm) of torque with a 20 kW electric motor.

Although this Jetta is VW's second hybrid, after the Touareg Hybrid, the Jetta Hybrid may be the first hybrid to use a seven-speed dual-clutch automatic transmission.

Exterior changes include a new front bumper, a rear diffuser and a trunk-mounted spoiler, and for another first on a Jetta - Xenon headlights. There's also a unique grille, hybrid badging and 15-inch alloy wheels with low-rolling resistance tires.

The Jetta Hybrid will become available sometime this year and will be "competitively priced with other compact hybrids," VW states.
