Regal GS spec confirmed

Buick has confirmed some technical specifications for its forthcoming 2012 Regal GS - and the big news is that it’s going to have slightly more power than originally thought.



When first announced in November last year, it was estimated that the 2.0 litre Ecotec turbocharged, four-cylinder, direct injection engine would produce 255 bhp (190 kW / 258 PS).



However, the GS has now been SAE certified at 270 bhp (201 kW / 273 PS). Peak torque, which is achieved at 2,400 rpm, remains at the previous figure of 400 Nm (295 lb/ft).

That’s plenty for a front-wheel drive car, and it adds up to a 0-60 mph (96 km/h) acceleration time of just 6.7 seconds. Anticipated Highway fuel economy is a fairly respectable 28 mpg US (33.6 mpg imperial / 8.4 l/100km), vindicating the decision to use a small capacity turbo engine rather than a normally aspirated six-cylinder unit.



Anticipating that torque steer could be an issue, Buick has fitted the GS with its High Performance Strut front suspension system. This is also engineered to maintain a negative camber during cornering, thereby helping the tyres grip better.



Other chassis elements include the Interactive Drive Control System, which allows the driver to choose from three modes that control suspension settings and steering response. ‘Standard’ is for everyday use, ‘GS’ is for press-on hard driving, and ‘Sport’ is somewhere in the middle of those two. Computer Damping Control meanwhile constantly adjusts the damping in response to changing road conditions.



Sales of the Buick Regal GS are due to begin this autumn.

Buick Regal eAssist hybrid

Buick has announced a ‘light’ hybrid version of its Vauxhall / Opel Insignia-based Regal.



Dubbed eAssist, the system combines a 2.4 litre four cylinder Ecotec engine, six-speed automatic transmission, lithium-ion battery pack, electric motor and regenerative braking.

The claimed result is 25% better fuel economy, with estimated EPA city and highway ratings of 26 mpg US (31.2 mpg UK / 9.0 l/100km) and 37 mpg US (44.4 mpg UK / 6.4 l/100km) respectively.



However, the electric motor isn’t intended to propel the car on its own. Rather, its 15 bhp (11 kW / 15 PS) is there to assist during acceleration, plus the system allows for fuel cut-off during deceleration and automatic engine shutdown when the Regal is stopped.



Located behind the rear seats, the lithium-ion battery pack and its the integrated power inverter do eat into luggage space, but there’s still 314 litres (11.1 cubic feet) left available. The electric induction motor / generator meanwhile is attached to the engine, taking the place of an alternator.

Other fuel saving measures include the fitment of 17” alloy wheels with low rolling resistance tyres, improved under-body aerodynamics and higher gear ratios. Additionally, the air conditioning can be switched to a fuel-optimisation setting that allows the engine to be stopped for longer periods.



To help drivers make the most of the technology, the instruments include an Eco gauge and the 7” infotainment screen can display how power is flowing around the hybrid system.



The Buick Regal eAssist is due to go on sale in North America this autumn, in time for the 2012 model year. Pricing has yet to be confirmed.

Buick unveils 2012 Verano

Buick has revealed the 2012 Verano, which will debut at this month’s North American International Auto Show in Detroit.

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.

Verano (above) compared to its close relation, the Astra (below)

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.

2012 Buick Regal GS

Buick has unveiled the halo version of its Regal, the model that’s based on the Vauxhall / Opel Insignia.

Called the GS, it will come with a turbocharged two-litre Ecotec four-cylinder engine connected to a six-speed manual transmission (a six-speed automatic will also be available later). An output of 255 bhp (190 kW / 258 PS) and 400 Nm (295 lb-ft) of torque promises brisk performance, with Buick estimating that the 0-60 mph (96 km/h) sprint should be achieved in under seven seconds.

But the Regal GS is front-wheel drive, which raises a rather obvious question: Why didn’t Buick simply badge-engineer the Vauxhall Insignia VXR (also known as the Opel Insignia OPC)?



Not only do the European cars get a 2.8 litre V6 turbocharged Ecotec motor with 320 bhp (239 kW / 325 PS) and 435 Nm (321 lb-ft) of torque, but they also feature permanent four-wheel drive. As a result, the VXR / OPC gets from 0-60 mph in 5.6 seconds, while top speed is electronically limited to 155 mph (250 km/h).



However, one benefit of sticking to just four cylinders is better fuel consumption. The manual and automatic versions of the Regal GS achieve Highway economy figures of  29.0 mpg US (34.8 mpg UK / 8.1 l/100km) and 28.0 mpg US (33.6 mpg UK / 8.4 l/100km) respectively, which is virtually identical to what the 220 bhp (164 kW / 223 PS) Regal CXL Turbo manages.



255 bhp is still a lot of horsepower to go through the front wheels, though. To help combat the inevitable torque steer, Buick has fitted High Performance Strut (HiPerStrut) front suspension which maintains negative camber during cornering.



Other chassis gizmos include active Computer Damping Control (CDC), which continuously modifies damper characteristics according to the road surface, and an Interactive Driver Control System that changes suspension settings and steering response depending on whether ‘Standard’, ‘Sport’ or ‘GS’ mode has been selected. Whether all of that technology is a substitute for all-wheel drive remains to be seen.



The Regal GS is scheduled to go on sale in the second half of 2011, so Buick is certainly making anyone who’s interested in the car wait for it.



Pricing has not yet been confirmed, but the GS will enjoy a decent standard specification which includes 19” alloy wheels (20” optional), Bluetooth telephone connectivity, passive keyless entry with push-button start, Harmon/Kardon 320 watt sound system with nine speakers, XM Satellite Radio, sports seats with leather upholstery, heated driver and front passenger seats, front and rear park distance control and bi-xenon headlights.

Arriving as a 2010 model, the new Buick Lacrosse is built upon the mid-size Epsilon II platform, which is also the basis for the Opel Insignia and the 2010 Saab 9-5.The design was based on 2008 Buick Invicta concept, and replaces both the Chinese and North American models. Buick states that the new LaCrosse will be "America's Lexus fighter".With the new 2011 Regal and the coming demise of Lucerne

Europeans in Detroit

Interesting to see a couple of re-badged European cars on display at the 2010 Detroit show earlier this month.



Following its takeover by Fiat, Chrysler clearly couldn’t be bothered to do too much with the Lancia Delta, not even going to the trouble of changing its model name. A minor tweak to the grille seemed to be enough.



The Chrysler Delta.  Or is it?

Buick meanwhile appeared to make a bit more of an effort with the Regal, its version of the Vauxhall / Opel Insignia. The GS shown featured a 252 bhp four cylinder turbo engine. Not quite the 321 bhp that the six cylinder Insignia VXR / OPC has, but it should still be rather quick, with a 0 - 60 mph time below six seconds.
