The Mild Hybrid Is Back… At Buick
According to a GM press release, the 2012 model-year version of the Buick LaCrosse is dragging a skeleton out of the GM marketing closet: the mild hybrid. But don’t you dare use the “m” word… it’s the eAssist.
Mated to a 2.4L Ecotec direct injection four-cylinder engine and next-generation six-speed automatic transmission, the eAssist system uses power stored in the battery to provide needed electrical boost in various driving scenarios, optimizing engine and transmission operation. An advanced 115V lithium-ion battery and latest-generation 15-kW motor-generator unit help increase fuel economy through:
- Regenerative braking, which provides up to 15 kW of electricity to charge the battery
- Providing up to 11 kW (15 hp) of electric power assistance during acceleration
- Automatic engine shut-off when the vehicle is stopped
- Aggressive fuel cut-off during deceleration down to zero vehicle speed, enabled by the torque smoothing provided by the motor-generator unit
- Intelligent charge/discharge of the high-voltage battery.
But most importantly:
While the eAssist system shares the same basic belt-alternator-starter configuration of previous BAS designs, it delivers more than three times the power and is much more capable than the previous-generation BAS system.
Buick says this will be the standard powertrain option for the LaCrosse starting in 2012, and along with aero and tire tweaks will loft the model’s mileage to (shout it) 37 MPG highway and (whisper it) 25 city. The price: 65 lbs and a $2k-$3k sticker increase to “about $30,000”. The Lacrosse has sold well this year (by recent Buick standards… 52k sales year-to-date), and the LaCrosse’s average transaction price is reportedly sitting at $32k… but that doesn’t mean this isn’t a gamble. The question now: will GM also drop a two-mode hybrid in the LaCrosse as threatened?

- Jeff I noticed the last few new vehicles I have bought a 2022 Maverick and 2013 CRV had very little new vehicle smell. My 2008 Isuzu I-370 the smell lasted for years but it never really bothered me. My first car a 73 Chevelle and been a smoker's car after a couple of months I managed to get rid of the smell by cleaning the inside thoroughly, putting an air freshener in it, and rolling the windows down on a hot day parking it in the sun. The cigarette smell disappeared completely never to come back. Also you can use an ozone machine and it will get rid of most odors.
- Lou_BC Synthetic oil for my diesel is expensive. It calls for Dexos2. I usually keep an eye out for sales and stock up. I can get 2 - 3 oil and filter changes done by my son for what the Chevy dealer charges for one oil change.
- Joe65688619 My last new car was a 2020 Acura RDX. Left it parked in the Florida sun for a few hours with the windows up the first day I had it, and was literally coughing and hacking on the offgassing. No doubt there is a problem here, but are there regs for the makeup of the interiors? The article notes that that "shockingly"...it's only shocking to me if they are not supposed to be there to begin with.
- MaintenanceCosts "GLX" with the 2.slow? I'm confused. I thought that during the Mk3 and Mk4 era "GLX" meant the car had a VR6.
- Dr.Nick What about Infiniti? Some of those cars might be interesting, whereas not much at Nissan interest me other than the Z which is probably big bucks.

No, you are not alone M1. It has gotten a lot more difficult, as you know, but some of us still do it.
(Old) GM's mistake was sticking BAS into everything they could, then actually adding weight (and hype) with waaaay too many flashy hybrid badges. This time, it would seem (New) GM has actually learned a lesson: This isn't the Lacrosse Hybird. It isn't even going to be marketed as such. If a fat pig like the Lacrosse can actually do 37 on the highway, that's definitely an improvement. Just don't call it a hybrid!
