2018 Buick LaCrosse gets a mild hybrid model, lower price

Update: Buick provided us with horsepower and fuel economy figures. The text has been updated to reflect this. Buick is rolling out a variety of updates for the 2018 LaCrosse, including a new mild eAssist hybrid. Like the previous generation LaCrosse and Regal eAssist models, this one features a small electric motor and an equally small battery pack that together augment rather than supplant the gasoline engine. The motor, attached to a 2.5-liter four-cylinder engine, helps to make takeoffs smoother and provide additional torque on demand. The gasoline engine still does the majority of the work, though. Combined, the powertrain produces 194 horsepower and 187 pound-feet of torque. It will also allow the LaCrosse to get 25 mpg in the city, and 35 mpg on the highway. While the electric powertrain doesn't provide primary propulsion, it does come with other benefits. The small battery means the LaCrosse maintains a folding rear seat. The battery also provides power to accessories when the engine shuts off at a standstill. This mild hybrid powertrain will be the standard engine for all 2018 LaCrosses, and they come with a lower base price. The 2018 model will start at $31,415, which is about $1,500 less than the lowest priced 2017 V6 LaCrosse. The V6 will still be available as an option, and Buick has updated it, too. The 2018 V6 models will also all come with a new 9-speed automatic transmission. The new LaCrosses will go on sale this fall. Related Video: Image Credit: Buick Green Buick Hybrid Luxury Sedan

Question of the Day: Best recipient for supercharged GM V6?

The good old Buick V6 engine was built from 1961 through 2008 (including a decade of production by Kaiser-Jeep) and went into way too many General Motors vehicles to list here. In 1991, the supercharged version of the 3800 was introduced, with a Roots-style Eaton blower on top, and now you can find these engines in just about every junkyard in North America. The 3800 shares a bellhousing pattern with the also-made-by-the-zillions GM 60° V6 engine, which means that it will install (with varying levels of sledgehammer clearancing and/or axle mix-and-matching) into plenty of GM vehicles that never received the 3800 from the factory. That means one thing: engine swaps! An excellent example of this is the 1992 Chevrolet Lumina APV "Dustbuster" minivan, which is a fully caged high-performance road-racing machine that features a supercharged 3800 and 5-speed manual transmission under its long, vacuum-cleaner-snout-like hood. The RaceVan, in Springfield Monorail livery, will compete this weekend at the Michigan 24 Hours of LeMons race with Autobloggers Mike Austin, David Gluckman, and Alex Kierstein at the wheel. My personal choice for supercharged 3800 power, though, has to be the Cadillac Cimarron, preferably the not-so-sought-after Cimarron d'Oro Edition. Some bashing and welding and cutting and pasting and this lightweight Cavalier sibling could have well over double its original horsepower. So, what's your blown 3800 engine-swap choice?

Buick rolls out more potent Encore Sport Touring

Buick has announced a new Sport Touring version of the Encore. And more than a trim level or special edition, we're glad to report that the new model packs a more potent engine. Instead of the 1.4-liter turbo four that produces 138 horsepower and 148 pound-feet of torque in the standard Encore, the new Sport Touring model features a newer, more powerful engine that GM says shares little with the existing unit aside from its displacement. The new 1.4-liter turbocharged, direct-injection engine produces a more commanding 153 hp and 177 lb-ft of torque, which is up a good 11 percent and 20 percent, respectively, over the existing engine. It's still mated to a six-speed automatic transmission, and features a stop/start system to optimize fuel efficiency. Buick wasn't willing to estimate where the mile-per-gallon numbers might land, though that information will be available closer to sale. Along with the upgraded engine, Buick is also throwing in 18-inch wheels, a rear spoiler, and the features from the Convenience package as well. The new Encore model follows just a couple of months after we first caught wind of a trademark filed for the Sport Touring name. At the time, it looked like it was set to be applied to the Regal and LaCrosse sedan, which could still follow as well.

It is distinguished by unique exterior cues and driven by an exclusive, all-new 1.4L turbocharged engine featuring direct injection and stop/start technology. The exterior features include a winged rear spoiler, 18-inch aluminum premium-finish wheels and body-color door handles, while the technologically advanced 1.4L turbo is part of a new, global family of small, power-dense engines developed to balance performance and efficiency with exceptional refinement. Direct injection helps it generate an estimated 153 hp (112 kW) and 177 lb-ft of torque (240 Nm), for about 11 percent more horsepower and nearly 20 percent more torque than the Encore's standard engine – and a greater feeling of power on demand, particularly at low- and mid-range engine speeds. It's matched with a six-speed automatic transmission. Stop/start technology contributes to reduced fuel consumption in stop-and-go driving.
