Buick's compact luxury Verona is getting its own version of the 2.0L Ecotec turbocharged engine and direct-injected engine used in the Buick Regal and Cadillac ATS. It will be offered for 2013 in a new top-of-the-line Verano Turbo model, which will go on sale later this year.
The engine, which also features continuously variable valve timing, will be rated 250 horsepower at 5300 rpm and 260 lb-ft of torque at 2000 rpm. More than 90 percent of its peak torque – more than 234 lb-ft – is said to be available all the way from 1700 to 5500 rpm.
Acceleration from 0-96 km/h 60 mph is estimated to take 6.2 seconds.
But it's not intended to be a performance model. "The 2.0L turbo engine was designed for refinement, higher output capabilities and reduced noise," said Amy Joss, Ecotec 2.0L assistant chief engineer. "The way it sounds, the power delivery and the refined character are all fitting of a luxury sedan with a fun side."
The choice to use a small-displacement turbocharged engine for a more powerful Verano model is consistent with Buick’s effort to downsize its powertrains without sacrificing performance. The Verano and Regal are available exclusively with four-cylinder engines.
At this point, the e-Assist system offered with the four-cylinder engines in the Regal and laCrosse is not offered on the Verano. Yet'
echnology, which uses an electric motor and battery to boost both performance and fuel economy. The standard 2013 Regal four-cylinder engine also is equipped with eAssist.
ccording to IHS Automotive, use of four-cylinder engines in North American vehicles will grow 74 percent from 6.9 million to 12.2 million units over the next 10 years, so Buick appears to be ahead of the curve.
The Verano Turbo will be available with a choice of a six-speed automatic transmission or a six-speed manual gearbox. Acceleration is expected to be consistent between the two transmissions, GM says.
Fuel economy numbers are not final, but the Verano Turbo is expected to be in line with Buick’s other turbocharged models. Pricing will be announced closer to the start of production in late 2012.
