The official performance and fuel economy numbers on the 2012 Buick Regal GS are out. When GM revealed the Buick’s sports sedan in production trim at the Detroit Motor Show this past January, the company estimated that the Regal GS was good for 255HP and a 0-60mph time of less than 7 seconds. Now GM announced that the Regal GS’ 2.0-liter direct-injected turbocharged four-cylinder engine has been SAE-certified to deliver 270 horsepower (201kW) and 295 lb.-ft. of torque (400Nm) fat 2,400 rpm or an estimated 0-60 mph performance of 6.7 seconds, or 0.9 seconds slower than the car’s European sibling, the Opel Insignia OPC that features a 325HP V6 and AWD.
It’s model-year changeover over time for the Vauxhall Insignia with the British company announcing the addition of a low emissions ecoFLEX diesel model and a new-to-the-range 1.4 Turbo petrol engine.
Last month we wrote about the Opel Corsa OPC Nurburgring Edition, a 210HP version of which only 500 units will be built. Opel had initially released three photos of the new car but now, the German carmaker returns with a bevy of new pictures of its pocket rocket. Naturally, all shots are taken at the Nurburgring racetrack, on the old Nordschleife section as well as on the modern Grand Prix circuit. Opel didn't offer any new information on the car aside from announcing that the average fuel consumption is 7.6 liters/100 km (30.95 mpg) with corresponding CO2 emissions of 178 grams per kilometer.
Following last month’s presentation of the Opel Insignia OPC Unlimited, Vauxhall introduced its own version of the performance sedan with the VXR moniker featuring the de-restricted package. The Unlimited option removes the standard Insignia VXR’s 155mph (250 km/h) restrictor, allowing Vauxhall’s range-topper to exploit its all-wheel-drive chassis and 325HP turbocharged 2.8-litre V6 engine to the full topping out at 170mph (274 km/h).
