The debut of the production Nissan GT-R remains one of the hottest happenings in the automotive world this past year, but the return of the GT-R to Japan’s SuperGT series is of equal importance. We’ve already seen what the new racer will look like as it gears up for its assault on the GT500 class, and today, Nissan finally released all the technical details about the SuperGT competitor. Let the bench racing begin.

As rumored, the GT-R will be powered by the VK45DE V8 that’s been successfully campaigned in the 350Z over the last two years. The naturally aspirated mill produces 500+ hp and well over 376 lb.-ft. of torque. The 4.5-liter sends power to a six-speed sequential gearbox and on down to the rear wheels. Nissan opted for the V8 instead of the production GT-R’s twin-turbo’d 3.8-liter V6 because the new mill is still too green to compete in the upper echelon of motorsport and the torque output isn’t up to GT500 standards – something that’s key to competing in SuperGT.

Nissan’s Works program will be fielding five GT-Rs spread across four teams, with the first race set to begin March 15-16 at Suzuka.

Saab has got its work cut out for it over the next few years, as it attempts to recreate itself – once again – by offering a slew of new products that will hopefully differentiate it from the rest of the General’s line. The next big small thing from Saab is the 9-1 concept, which aims to compete with the BMW 1-series, the Audi A3 and Volvo’s C30.

Originally, the 9-1 was supposed to make its debut at the London Motor Show, but Saab designer Anthony Lo divulged to Auto Motor Und Sport that the new hatch would be unveiled this March at the Geneva Motor Show.

Details about Saab’s new compact offering are still scarce, but expect styling to be heavily influenced by the Aero X concept, with power provided by either a turbocharged 1.4-liter four or a BioPower mill.

Nissan’s original Murano was a successful and difficult act to follow. The elder statesman of crossover utility vehicles saw its sales increase every year since it was introduced in 2003, but with the segment going from crowded to standing room only, Nissan realized changes were needed to compete.

“Murano-ness” – that’s what Jarrad Haslam, Nissan’s product planner for crossovers, said the company insisted be preserved in the new version. Nissan invited us to Atlanta to sample this almost-totally-new Murano for 2009. You’ll recognize the distinctive rounded nose, sharply-raked windshield, the side glass kicked up over the rear fender, a smallish rear hatch window topped by a sliver of a spoiler, and a lower rear bumper accentuated by dual exhaust outlets. But put the 2007 and 2009 (the Murano sat out the 2008 model year) side by side, and the differences become evident.

None of us happen to subscribe to AutoWeek anymore, so we have to take Inside Line Senior Editor Ed Hellwig at his word that the latest issue of the weekly car rag includes another embargoed image of the 2008 Dodge Challenger SRT8 that you’re not supposed to see until next week. It’s a good one, though, being the first official pic to get out that shows the production derriere of the Challenger.

Obvious changes include a different light bar across the back that’s comprised of traditional lamps instead of the slick set up on the concept car. The rear back up lights have been combined into a single unit that now sits in the middle of the taillamp assembly, and light markers on the rear fenders have been moved down, as well. There’s the new black spoiler perched on the Challenger’s deck lid, which, combined with the black front lip spoiler, is a perfect retro touch. Finally, the concept’s dual split exhaust outlets are now more traditional dual rectangular ones. All changes for the better, if you ask us.

Look for our live coverage of the 2008 Dodge Challenger SRT8′s debut at the 2008 Chicago Auto Show early next week.
