I verified this repeatedly at Watkins Glen where the higher-trim cars with the same HP pulled away from the lower-trim cars around every corner.
Adding a manual transmission also changes the car's character. The manual is used in some of GM's sportier Astras, so shifts are short, it's easy to shift quickly, and the first few gears are pretty short. So the car will accelerate rather briskly off the line since it can be wound out to redline in 1st and 2nd.
Lastly, being a turbo GM car, there's a healthy aftermarket. Tunes make a reliable ~25 hp/50 ft/lbs. Going from 138 hp to about 163-165 hp and 148 ft/lbs to ~200 ft/lbs also changes the car for the better. If modding strikes anybody's fancy, that is.
That's all great to know, but HOW does one pull weight/mass off of that car/platform, if at all?
Are there aftermarket lighter weight parts available to trim the 3000 Lb.+ mass?
I ask
NOT to put down the car at all, as I LOVE the way it looks, and rides, but as a serious query if I decide to look at another used one some day.
Buy the lightest one out there and start gutting the interior. The Eco manual transmission weighs ~3000 lbs ready to hit the road, minus the driver. It's still porky for its class. There are no real ways to lighten it that I know of. GM used a lot of metal in the body, and it shows.
The real solution to your dilemma is adding power to overcome the weight. The Buick Verano, which as of right now shares a platform with the old Cruze, comes in a 260 hp version, with upgraded tires and brakes to match. There are chiptunes available that will get ~25-30 hp and 50-55 ft/lbs on the Cruze for $350. The same tuner also works their magic with similar gains on the Verano Turbo. Of course, finding a Cruze in decent shape is a lot easier than finding a Verano Turbo, much less one of the rare Turbo models with a 6-speed manual.
