Along with the 2011 Sonata mid-size sedan, Hyundai also introduced the North American-spec 2010 Tucson SUV at this week's Los Angeles International Auto Show. Like the latest Sonata, the new Tucson boasts a funky exterior design that's far more exciting than its dull predecessor and a significantly upgraded with a much more modern and premium look.

With an overall length of 173.2 inches, a width of 71.7 inches and a height of 66.3 inches (with roof rails), the 2010 Tucson is 3.3 inches longer and one inch wider than its predecessor. However, according to Hyundai, it's 61 pounds lighter than the outgoing model.

The new Tucson uses MacPherson strut front and multi-link rear suspension systems while for the first time, Hillstart Assist Control (HAC) and Downhill Brake Control (DBC) systems will be standard.

When the 2010 Tucson arrives at Hyundai's U.S. dealerships later this month, it will be offered with a Theta II 2.4-liter four-cylinder engine connected to either a either a six-speed manual or an optional six-speed automatic. This unit replaces the current model's 2.7-liter V6.

Unlike the new Sonata's 198HP Theta II 2.4L engine, the Tucson's Theta II does not feature direct injection. Hyundai rates the Tucson's unit at 176 horsepower and 168 lb.-ft. of torque, meaning it's slightly more powerful but less torque than the current model's 2.7-liter V6 that makes 173HP and 178 lb-ft.

However, the new four-cylinder unit is significantly more fuel efficient as Hyundai claims that with the available six-speed automatic transmission and front wheel drive, the new Tucson returns an estimated 23 mpg city / 31 mpg highway compared to the current Tucson FWD Auto's 18mpg / 24mpg respectively.

In fact, Hyundai says that the new Tucson is more fuel-efficient than the four-cylinder versions of the Honda CRV, Nissan Rogue, Toyota RAV4 and Ford Escape.

With AWD (All-Wheel Drive), the new Tucson delivers an estimated 21 mpg city/28 mpg highway.

In addition to the 2.4-liter engine, Hyundai will introduce an even more fuel efficient Blue model for the 2011 model year. It will be powered by a Theta II 2.0-liter engine that's said to deliver better power and fuel economy than the 2009 Tucson Beta four-cylinder engine.

Sales of the 2010 Tucson will begin before the end of December with pricing expected to start under $20,000.
