2012 BUICK REGAL eASSIST
At the Chicago Auto Show, Buick announced that the second model in its lineup to feature the eAssist “light electrification” system is the 2012 Regal. Using estimated fuel economy is 26 mpg city/37 mpg highway, while the overall improvement over the standard 2011 Regal fitted with a four-cylinder gasoline engine and six-speed transmission is 25%.
The engineers optimized the car’s underbody aerodynamics and opted for 17-inch lightweight alloys and low rolling resistance tires. The 2012 Buick Regal eAssist will go on sale in the USA this fall.
2012 Buick Regal eAssist support by a 115V lithium-ion battery and 15-kilowatt induction motor-generator, which is mounted to 2.4-liter direct injection four-cylinder powerplant in place of the alternator. Providing both motor assist and electric-generating functions, eAssist also reduces fuel consumption through regenerative braking, automatic engine shut-off when the vehicle is stationary and fuel cut-off during deceleration.
Also equipped the powertrain includes a next-generation Hydra-Matic 6T40 six-speed automatic transmission as well, with reduced spin losses and higher gearing that further improves fuel economy. The system’s combined output is rated at 182HP (136 kW).
2012 CHEVROLET CAMARO ZL1
At the 2011 Chicago Auto Show, Chevrolet presented the 2012 Camaro ZL1. On the interior, Chevy’s top dog is equipped with sport seats clad in microfiber suede inserts, a flat-bottom steering wheel with a center hub.
The exterior flagship Camaro is distinguished by a new front fascia and hood with a signature center section constructed of carbon fiber and rendered in satin black finish, which also incorporates functional air extractors. The ZL1 also gets a redesigned front bumper, new rocker panels, a larger boot lid spoiler and four exhaust tips.
2012 Chevrolet Camaro ZL1 packs an LSA 6.2-liter supercharged V8 engine that’s good enough for an estimated 550 horsepower and a massive 550 lb.-ft. of torque (745 Nm), paired to a six-speed manual transmission with a dual-disc clutch system and a shorter-throw shifter. GM is keeping a tight lid on performance numbers for now, but with 550-ponies on tap, we gather the Camaro ZL1 won’t disappoint in the speed department.
The ZL1 also sports a series of chassis upgrades including a revised suspension with a Magnetic Ride Control system and a high-performance Brembo brake system with six-piston calipers up front and four at the back. A brand new electric power steering system and 20-inch lightweight alloy wheels shod in Goodyear Supercar F2 tires, are also part of the ZL1 package.
