G-Tech tested my 4 cylinder 'Bu today

So it's about one year later, time to G-TECH the 'Bu again! A little more broken in now, and using 5W-30 Mobil One oil. Here's the stats for today:

Same tires (Firstone FR710)
Mobil One 5W-30 synthetic
28 degrees F
5/8 tank of gas
Same roads, so 1000' altitude
19,134 miles on the ODO. I was at 33 mpg average on the computer just before the run.

Four runs, the first was 8.3 seconds 0-60. Second and 4th runs were at 7.8, the third run was at 8.0 even.

Averaging the four runs netted approx. 0-60 time of 8 seconds on a nice cool dry day.

Not bad for how heavy this car is. I think the biggest reason these cars can accelerate as well as they can is that nice 6-speed auto. When the engine shifts from first to second, the tach drops to 4900 rpms, so the engine is still well up in it's power band when hitting second gear.

Still loving it, and still driving it like an old man the rest of the year Will be back to this thread in another 12 months!

The 4-cyl and V6 use different 6-spds (the 4-cyl for lighter duty/less power applications than the one the V6 cars use), but otherwise, YES.

We just had to have one when we bought one, and from experience with a last gen 2.2L/4-spd Malibu, I didn't think it was a big deal. It's still a great car, but the powertrain performance could certainly be better--and it was nice to see how much so the first time I drove an early Spring Edition LTZ 4-cyl.

Interesting talking to 2 GM engineers about this once when they came to review my '09 2LT V6 for shuddering issues. I talked about our 4-cyl/4-spd car and the 6-spd changeover and rather than it not being ready at initial intro, they said the 4-cyl spec 6-spd was ready "we just weren't happy with the programming yet and still tuning". Hence why there were some 4-cyl/6-spd test mule cars they let press drive at the initial intro in late '07, but said "not yet...later".

Now just think about this car with the torquier DI 2.4L just introduced on the Equinox, from even the comments on power & mileage in that heavier & boxier 'ute. Should be a very nice change, soon enough down the line.
