2012 Chevrolet Sonic: We Autocross A Prototype Of Chevy's New Small Car
By Dan Edmunds | June 15, 2011
Sonic Youth? Sonic Boom? Sonic the Hedgehog? Super Sonic? Up 'til now, these have been among the top Google search terms around the word "sonic". But that's likely to change in the coming months once the 2012 Chevrolet Sonic hatchback and sedan hit the market.
Most of what we know about the all-new Sonic is a few specs and pictures. When Chevrolet recently invited us to sample a 2012 Chevrolet Sonic in Indianapolis, Indiana, we jumped at the chance.
The car, a silver four-door hatchback, was a prototype example of the sportiest variant with the sportiest engine and transmission combo that will be on the order sheet when the Sonic goes on sale later this year.
Equipped with the same direct-injected 1.4-liter turbo four found in our 2011 Chevrolet Cruze LTZ, the Sonic hatch in question churns out 138 horsepower anf 148 lb-ft of torque, easily outclassing its chief class competitors, the Honda Fit (117 hp / 106 lb-ft) and Ford Fiesta (120 hp / 112 lb-ft), as well as the Mazda 2, the Fiat 500 and others.
But we didn't just slalom a Sonic and be done with it. GM brought a Fiesta SES and a Honda Fit Sport out for us to thrash, too. And they set up timing lights.
Soon the tires were howling and the brakes were stinking. The orange cones wriggled, got knocked over a time or three and acquired some jaunty black accents.
Along the way the proto-Sonic proved to be a solid handling machine, with great grip and a pleasantly neutral chassis setup that allowed the rear end to dance around a bit with the stability control shut down. We love tossing around small cars, and the Sonic fits the bill just fine. This is clearly much more than a hopped-up Aveo.
It must be said that the Fit and Fiesta were just as fun, though the Fiesta in particular was hampered in this competitive setting by its 6-speed powershift automatic instead of a manual and a stability control system that couldn't be switched off or even dialed down a notch. The Fit seemed to roll a tad more owing to a higher seating position and a quicker steering ratio, but it stuck like anything and the high throne did offer a sweeping view of those pesky cones.
The time sheet, however, was all Sonic. It circulated the course in 47.5 seconds, some 1.8 seconds faster than the Fit and 2.6 seconds faster than the Fiesta.
It should be said that I've never driven on an autocross course with straightaways as long as these, so the extra power and torque of the Sonic's optional 1.4T engine had more than a little influence here. We can't discern which is the best pure handling machine from this contest, but the Sonic is certainly entertaining.
The Fit and Fiesta might have have stood a better chance against a Sonic on 16-inch tires (it can be had with 15-, 16- and 17-inch rubber) and with the Sonic's base engine, the same 1.8-liter normally aspirated four found in the Cruze. But even that engine easily bests the competition with 138 hp and 125 lb-ft of torque.
Thing is, the Sonic is unique in this segment in that it has an optional hot-rod engine; you can get wider tires; you can opt for 6 gears in you manual. The competition makes do with one engine and a take-it-or-leave-it 5-speed manual. Sure this top level Sonic creamed the others in what might be described as a lopsided contest, but that's because Chevy has chosen to offer a hotter version in the first place, and they didn't.
The insides of the Sonic prototypes weren't finished to production standards, as evidenced by a lack of final texturing on many of the parts. But we're still able to report a very clean and easy-to-use center-stack design, and we think the compact gauge cluster, comprised of an analog tach and a digital speedometer, is a pretty neat piece.
The back end of the hatchback contains some clever thinking. That sub-floor is removable enlarge the storage capacity; it slips down to the floor of the basement level so you don't have to wrangle it in your garage. And the flip up cargo cover that lifts with the hatch can be pushed forward and down as shown so you can disable it but still store it in the car.
Yes, the Fit still has them all covered with its hyper-low floor and magic seat, but the Sonic's hatch area is larger and far more flexible than that of the Ford Fiesta, its cross-town rival.
