On December 3, 2007, Chrysler started taking deposits for the 3rd-generation Dodge Challenger which debuted on February 6, 2008, simultaneously at the Chicago Auto Show and Philadelphia International Auto Show. Listing at US$40,095, the new version was a 2-door notchback coupe (seating 5 passengers with over 33 cubic feet of rear passenger volume) which shared common design elements with the first generation Challenger, despite being significantly longer and taller. As with Chevrolet's new Camaro, the Challenger concept car's pillarless hardtop body was replaced with a fixed "B" pillar, hidden behind the side glass to give an illusion of the hardtop. The LC chassis is a modified (shortened wheelbase) version of the LX platform that underpins the Dodge Charger (LX), Dodge Magnum, and the Chrysler 300. The LX was developed in America from the previous Chrysler LH platform, which had been designed to allow it to be easily upgraded to rear and all-wheel drive. Many Mercedes components were incorporated, or used for inspiration, including the Mercedes-Benz W220 S-class control arm front suspension, the Mercedes-Benz W211 E-Class 5-link rear suspension, the W5A580 5-speed automatic, the rear differential, and the ESP system. All (7119) 2008 models were SRT8s and equipped with the Hemi V8 engine and a 5-speed AutoStick automatic transmission. The entire 2008 Canadian produced run of 6,400 US market cars were pre-sold and production commenced on May 8, 2008.
