As with the larger Regal, the Verano is based on a Vauxhall / Opel model, in this case the Astra.
And why not? It makes sense for GM to have a slightly more upmarket alternative to the Chevrolet Cruze in North America, a role that the Astra fulfils in Europe. Such a strategy will also give the company further economies of scale from its Delta II compact car platform, which also underpins the Cruze and Astra as well as other models such as the Chevrolet Volt.

What differentiates the Verano from its European cousin is the four-door saloon body (the Astra is only available in five-door hatch and estate guises) and the choice of engine. For now, power will come from a 2.4 litre Ecotec four-cylinder motor that produces around 177 bhp (132 kW / 179 PS) and 230 Nm (170 lb/ft) of torque.
Coupled to a six-speed automatic gearbox - no manual is available - Buick reckons it should be good for a 0-60 mph (96 km/h) time of about 8 seconds, while an EPA Highway rating of 31 mpg US (37.2 mpg UK / 7.6 l/100km) is expected. A 2.0 litre turbo engine is due to join the range at a later date.
High levels of luxury and refinement were the focus during the Verano’s development and, to help achieve the latter, extra sound insulation, triple-sealed doors and acoustic glass have all been employed. Buick must be confident about the results, because it’s citing the Lexus IS 250 and Audi A3 as target competitors.
The 2012 Buick Verano will go on sale during the fourth quarter of 2011. Pricing has yet to be confirmed.
