After years of happily driving one $1500 E36 M3heap after another, I finally broke down in late August and bought something new enough to require a loan, and have a warranty. I needed something in the $8k range, reliable, good mpg, and relatively practical. I looked at several Mazda 2s (liked a lot, but a little lacking in the oomph department, and I couldn't find one with cruise around here), a couple of Fiat 500s (the N/A ones didn't do much for me, the backseat was useless, and my budget wouldn't quite stretch to an Abarth) and various Fiestas and Foci (which I liked).

But I wound up with a 2012 Chevy Sonic LT hatch. 48k miles, 1.4t 6-speed, not loaded, but nicely appointed. I've put about 4000 miles on it now, and here's what I know.

-Mileage is great. I average about 28 around town and that's driving it hard. On the highway at 75 I get a steady 38-39 with the air off. The downside to that is that it is the gearing....passing on the highway requires a 6-4 downshift. The mileage computer in the instrument cluster is consistently ~2 mpg optimistic, but apparently that's not unusual for GM vehicles.

-Stock power is good. It's pretty spunky for an econobox. Apparently the computer limits boost in order to stay below an arbitrary torque limit to preserve the transaxle...you can definitely feel the boost fall off as you accelerate. It's not linear, and it's a little disconcerting. Apparently a tune "fixes" that. I'm going to do the Trifecta tune as soon as I can convince myself that it really can't be detected if I have to reflash it to stock and take it in for warranty work.

-Design is neat. I really like the instrument cluster with the big analog tach and digital everything else. Seats are comfy, ergonomics are great, and visibility is good.

-Handling and braking are good by stock economy car standards. It's nippy. Feels planted. Brakes are good, and you can disable the traction control if you feel like hooning.

-Seems to be put together nicely. I've owned a lot of economy cars, and this one definitely has the nicest interior materials, most consistent panel gaps, nicest paint, etc. The map light keeps falling out of the headliner for some reason, though, and the steering wheel is pretty plasticky. I'm going to try to upgrade to the wheel from an LTZ or RS at some point.

Minuses: Mostly niggles.

-Why the hell does it not have a water temperature gauge??! Seriously, GM. Get your E36 M3 together.

-Air dam scrapes over lots of stuff. Seems relatively resilient though.

-Overall the packaging is pretty decent (four 6 ft adults fit in a car that's like three inches longer than an NA Miata), but I'd gladly take a slight size penalty for some more cargo space.

-The oil drain plug is a 10mm bolt that is apparently super easy to round off. Mine was rounded off when I got it, and the local chevy dealer says they keep several in stock because it happens a lot. New drain plug is $18. For a 10mm bolt.

-For a motor with a turbo this small, it's pretty easy to catch it off-boost. That combined with super-tall gearing (75 mph is ~2100 rpm in 6th) means a lot of rowing. Not that that's a huge problem.

-Knowledge base is not particularly knowledgeable. The forum for this thing ain't great. It's not ForteForums bad, but it's certainly in the neighborhood. There do appear to be some knowledgeable guys, but there are also a lot of guys talking about neon lighting and flush wheels. I think GRM has spoiled me.

All in all, I'm really digging this car. For the money I spent, I think this should be a solid commuter for a very long time. Given GM resale value, and the fact that they are selling a ton of these, there's a lot of value to be had here.

The only upgrades I have planned are a Trifecta tune (more power, more torque, supposedly even better mpg), upgrading the stereo, and swapping a leather-wrapped steering wheel from an LTZ or RS.

Re: the water temp gauge, welcome to pretty much every new vehicle these days. My Fit is the same way...

Sounds like a solid little car otherwise, though. I was toying with the idea of an LTZ before I ended up with the Honda.

I wouldn't worry too hard about the water temp gauge as I am positive that if it had one, it would be a dummy gauge. Cars on and not overheating, dead smack center of the gauge until it crosses 220. Then it starts yelling at you without warning.

I've never seen an oil drain bolt that small, 10mm? Seriously?

Interesting to hear they've gotten that cheap. Maybe I should add one to my list of things to consider for my next DD.

Ford broke down and put a sort of a gauge on the Fiesta. Makes you feel better.

These are definately on my radar. Mazda protege5 is coming up on replacement.

Yes, on all the GM 1.4L and 1.8L. And they have a really short head that makes them easy to round off. See it all the time at the dealership. The torque spec is 14 in-lbs but people crank the living daylights out of them

10mm head, but how big is the threaded portion?

NAPA has a nice catalog for drain plugs listed by every manner of dimension. Might find something sweet that fits the hole and is easier to use. Rarely over $5.

FYP. 220 isn't that hot on a modern car. For most cars, that's where the high speed fan really turns on. It tries to not go over that, but it's happy to hit it.

Take the rounded off drain plug and weld on a proper Manley sized nut.

soooo, I would MUCH rather have a rounded off drain plug than a stripped pan. Just sayin. Maybe its a feature?

nice write up. It sounds like this car needs a fumoto valve.

Its m14x1.50 but its really short and threaded straight in the bottom of the pan. We keep replacements handy. Took a while to find the correct length from service pro though. 4.38 each you just have to buy a box of 12.

It'd be nice, but like dropstep says, it comes straight out the bottom of the pan and there's a plastic belly pan that would have to be "clearanced". Even if I did that, I'd still be worried about the potential to drag it and break it off or crack the pan.

I bought my 2012 Sonic LT 1.4t 6-speed back in October of 2011. I'm at 38,000 miles and have had the Trifecta tune since December of 2011.

The car is fun. The plastic swaybar droplinks are crap. If they start rattling, you can use the steel ones from a 2008-2010 Cobalt SS. I got the Moogs with grease zerks.

If you truly want to disable traction/stability control, remove fuse #30. It controls the ABS pump.

Rockauto has the replacement drain plug as well, just over $7 each, but sold in packs of 10. Not sure you would need 10 though, unless you let gorillas change your oil. Definitely a small hex head for a fairly large drain plug. I wonder if they did that on purpose to prevent stripping the oil pan.

Good to hear your thoughts on the Sonic, I have wondered how they drive as I haven't met anyone who has one.

What kind of a difference have you noticed with the Trifecta tune? Both in power and mpg?

I get them as rentals fairly often, (1.8/auto), and have no problem with them for rental duty. Not entirely sure I'd buy one, but I have nothing against them. Definitely more comfortable than the Versas and Accents I get occasionally.

I've seen those go as early as 15,000 miles. And when they go bad, they sound like the whole front of the car is falling off. GM even had a campaign involving the replacement of them

On the dyno here at school, I went from 120hp/124lb/ft to 150hp/170lb/ft at the tires. The power band is okay, but the delivery could be smoother. Based on reviews however, I have been looking into the EFILive tune available from BNR (Bad News Racing). It's supposed to be a lot smoother and not fall off as dramatically on the top end.

MPG wise, I didn't notice a significant difference from stock.

Yep. Mine was a very early build. They started making noise within 5,000mi. I didn't even bother getting them warrantied. Straight to RockAuto for real ones.
