Opel and Vauxhall have announced the lineup of debuts for the upcoming 2012 Geneva Motor Show, with the highly-anticipated Astra OPC/VXR headlining the booth.

The aggressively designed Astra OPC/VXR will be powered by a turbocharged 2.0L powerplant with 277-hp and 295 lb-ft of torque and will also sport High Performance Struts (HiPerStruts), a FlexRide chassis, and lightweight bucket seats in the interior.

Next on Opel’s list will be its new Mokka crossover which is based on the Buick Encore. It will be released with three different engine choices available, a standard gas 1.6L with 113-hp, a turbocharged 1.4L with 138-hp and a 1.7L CDTI diesel with 128-hp. Front-wheel drive will be standard on the new Mokka, but all-wheel drive will be an option. Opel also mentioned in their release that all Mokka models will come with Electronic Stability Control (ESC), Traction Control (TC), Hill Start Assist (HSA), and Hill Descent Control (HDC) as standard.

The Insignia BiTurbo was also announced as a debut, featuring a 2.0L twin-turbo diesel engine with 192-hp and 295 lb-ft of torque.

Not exactly automotive related, but Opel and Vauxhall will also show off a RAD e electric bike concept. They described it as the “first e bike to be built around automotive construction and production principles.” The RAD e electric bike will show off a 250-watt motor that can give it an electric-assisted range of 37-90 miles.

Opel will also have refreshed variants of their Corsa, Meriva, and Astra at the show including their Corsa Kaleidoscope edition, a Meriva 1.4 LPG Turbo ecoFLEX model and an Astra 1.4 LPG Turbo ecoFLEX model.

One of Zagato’s most beautiful concepts in recent memory, the Alfa Romeo TZ3 Corsa, has been confirmed to be set for production—and it will ride on a Dodge Viper chassis, as well as its v10 engine.

The Corsa owes its production to the strange bedfellows between Alfa Romeo and Dodge, both a part of the Fiat/Chrysler conglomerate. As such, Dodge will lend the Viper chassis as well as a massaged 8.4-liter V10 that will deliver over 600 horsepower. Italian-American fusion hasn’t come together so well since the Chrysler TC by Maserati, or Olive Garden.

The TZ3 was unveiled at the Concorso d’Eleganza Villa d’Este about a year ago, as a continuation of Zagato’s equally-collectible TZ1 and TZ2 specials. The TZ3 was originally a one-off for a wealthy customer, but why should he have all the fun? Zagato will churn out a limited-production run in street-ready Stradale trim, presumably for other wealthy customers to whom we can grovel for a ride.

Ready to give the Lingenfelter Camaro a run for its money, the team at SpeedFactory will unveil a 440 cubic-inch Dodge Challenger SRT8 with as much as 700-hp. The power increase comes thanks to a supercharger, but that’s not all. The 440 cu.-in. (7.2-liter) engine is a big step up from the already huge 6.1-liter V8. And to make the package even better, it uses a Mopar block made of lighter aluminum – rather than the heavy factory iron block. The heads are also aluminum and the all-new internals are forged.

Getting all that power down is made possible thanks to a Mopar transmission and a new rear end that can handle up to 1,000-hp.

Other highlights on the car include a Corsa stainless steel exhaust, new 20-inch wheels with Bridgestone R Compound tires, 15-inch Brembo rotors, stiffer springs and anti-roll bars, as well as a chassis brace.
