General Motors has finally come out and said exactly what kind of power the 2012 Chevrolet Impala will bring to the table when it debuts later this year. In February, we heard that the aging full-size four-door will come with a 3.6-liter V6 under the hood mated to a six-speed automatic transmission, though at the time, The General elected to skip handing out any specifics beyond displacement. According to GMInsideNews, the 2012 Impala will pack a full 302 horsepower and 252 pound-feet of torque in standard trim when it touches down.

The 2012 Buick Lacrosse is set to receive the same updated 3.6-liter V6.

Unfortunately, those impressive numbers are to be the sum total of the updates that GM has planned for the Impala. The model has been on sale in its current configuration since 2006 and a full update isn’t scheduled to land until 2014 at the earliest. Still, as GMInsideNews points out, the refreshed six pot gives the 2012 Impala almost as much power as the old Impala SS – not too shabby.

2011 Acura RL presents slight changes to an aging package

For the 2011 model year, Acura has freshened up its flagship RL sedan. What exactly does “freshened up” mean when it comes to the RL? It may not look like much more than a cosmetic touch-up, but there are quite a few new tricks going on under the nip-tucked skin.

The 2011 Acura RL continues to utilize the 3.7-liter V6 engine with 300 horsepower that powers all four wheels courtesy of the Super Handling All-Wheel Drive system. New to the powertrain, however, is a six-speed Sequential Sportshift automatic transmission. It’s a smooth-shifting unit that allows for the occasional sporty dash courtesy of the wheel-mounted paddles while also improving fuel economy by two miles per gallon on the highway – EPA ratings come in at 17 mpg city and 24 highway.

An upgraded gearbox is nice and all, but since this is an Acura we are looking more for new technology. The 2011 RL is fitted with Hemholtz resonators in the wheels (a “world’s first” for a passenger vehicle). These chambers sit in the center portion of the inside of the wheel and help diminish road noise, which results in a quieter cabin. Coupled with increased floorboard insulation, the 2011 Acura RL behaves like a library out on the road. Unless of course you twist the knob for the ELS audio system.

Up front, the grille of the 2011 Acura RL has been revised to soften the angry-hawk nose while retaining a signature Acura look… opinions are divided on how successful the new schnoz may be. Brand new 18×8-inch 15-spoke aluminum wheels help fill out the wheel wells and get wrapped in Michelin Pilot all-season rubber.

Overall, the changes to the 2011 Acura RL are minimal, minus the upgraded transmission and in-wheel noise reduction technology. We had a chance to very briefly sample the ’11 model on the roads north of San Francisco and there’s unfortunately not much to get excited about. The rest of the lineup, regardless of how one feels about the styling, presents a sporty driving experience that doesn’t eat into the luxury. The RL feels heavier than it should while presenting a driving sensation that feels much more aged compared to its Acura siblings. We understand that its aimed at a different segment of the market, but that doesn’t mean it should lose the driving characteristics long-time Acura buyers have come to expect.

Chevy Volt’s “maintenance mode” will burn gas to prevent aging

When General Motors conceived the electric powertrain for the Chevrolet Volt, the 40-mile electric driving range was specified so that most drivers would rarely, if ever, have to use any liquid fuel. Components like the battery were then sized to match the performance and range specifications. However, the whole point of incorporating the range extending engine was so the Volt could keep going without the driver having to continuously monitor the battery level, even though GM once told us that the Volt would move without gas in the tank.

Regardless, leaving the same gasoline in a tank for months or even years creates a new set of problems. One reason is there’s no such thing as pure gasoline. What’s sold at the pump is a blend of numerous hydrocarbon compounds like octane, heptane and other additives that lubricate valves and fuel injectors, along with a range of assorted chemicals. Many of these compounds will eventually evaporate, reducing the performance of the fuel and could possibly lead to engine damage.

To address this, the Volt has a completely sealed and pressurized fuel tank. Pressurizing the tank helps minimize evaporation from the liquid fuel, forcing it to stay in liquid form. Before the fuel filler can be opened to gas up the Volt, the tank has to be depressurized, which takes a few seconds after pressing the release button. The engine management system also monitors the time between when the engine runs and will periodically prompt the driver to run past the 40-mile electric range before recharging. If the driver doesn’t force the Volt to run on gas, the system will eventually start the engine to consume some of the aging fuel and circulate the fluids within the engine. Once this maintenance mode is complete, the engine shuts down until it’s needed again or enough time has passed. GM hasn’t revealed what the time intervals are, but with Volt production right around the corner, we’ll find out soon enough.
