When Buick Verano's turbo version arrives in dealerships this fall, prospective buyers will encounter a luxury sedan capable of 250 horsepower, 260 pound-feet of torque, and 0-60 acceleration in 6.2 seconds; and with a price tag of $29,990.

The Verano Turbo's EPA rating is 20 miles per hour city, 31 highway. Fuel-efficiency numbers for the six-speed manual transmission, available at no increase in cost, will be announced closer to the car's release. Buick brags that the Verano Turbo with automatic transmission has horsepower and fuel efficiency superior to those of the manual-transmission 2012 Lexus IS250, which yields 204 horsepower and has an mpg rating of 19 city, 28 highway.

Powering the car is an Ecotec 2.0-liter four-cylinder engine with direct injection, continuously variable valve timing, and dual exhaust.

Standard features include sport pedals and rear spoiler, IntelliLink connectivity, a Bose audio system, leather-appointed upholstery, rear park assist and rearview camera, and radar-based side blind zone and rear cross-traffic alerts. A navigation system is optional.

"Buick Verano continues to build momentum in the marketplace with eight straight months of sales increases since launch," said Tony DiSalle, vice president of Buick marketing. "The new Verano Turbo increases the performance of an already capable luxury sedan while continuing to offer customers the smart, purposeful technology they expect."

The non-turbo version of the Verano went on sale late in 2011, with a 2.4-liter Ecotec engine and automatic transmission the only option. It has experienced a climb in sales each month it has been on the market, and sold 4,245 units in July.
