No cars introduced in the last year are more relevant to Sport Compact Car readers than the all-new 2006 Honda Civic Si and the just-as-all-new 2006 Volkswagen GTI. On paper, they're a well-matched pair of sport-oriented, $20K, 200-horsepower front-drivers. In real life, buyers will be cross-shopping them constantly. And when it comes to on-track competition, they will consistently be pitted against one another. There's never been a more glaringly obvious comparison test in the history of this magazine. Now here's the dilemma: This comparison is so self-evident that it's already been done by Motor Trend, Automobile, Car and Driver, Road & Track, MPH (God rest its adolescent soul), Edmunds.com, Ladies' Home Journal, Vogue Thailand, and Cat Fancy. SCC can't avoid this comparison, and yet what can we do that doesn't repeat what everyone else has done?
After much unrealistic and grandiose mis-planning, it was decided to narrow the question for our test to one simple aspect of performance: autocrossing. And instead of just delivering our vaunted editorial opinion, we'd put autocrossers of various experience in the driver seat and get their opinions too.
So we borrowed a GTI from VW ($22,260 base price and $24,175 as tested), a Civic Si from Honda ($20,540 base, $22,790 as tested) and then called up The Tire Rack (www.tirerack.com) and asked them to send us two sets of wheels wrapped in P225/45ZR17 Avon Tech R-A competition radials -- one for the Civic and one for the V-Dub. Since both cars would be running on the same make, model, and size tires, we'd factor that out of the competition. Plus, the Tech R-A is both a popular and excellent autocross tire with a high-grip racing compound and slick-faced tread surface with two circumferential tread grooves. Since the Tech R-A is born with a 4/32-inch tread depth, there was no need to shave them before heading to the course, but The Tire Rack did heat-cycle them before wrapping them around silver 17x8 OZ Ultraleggera wheels for the VW and gold 17x8 Ultraleggeras for the Honda. Each set retails for $1,704, with the tires mounted and balanced from The Tire Rack. It was just a matter of finding an autocross to attend.
The Place, The Event
Conveniently, the San Diego Asebring Drivers had organized the San Diego Region Solo II Championship for the April weekend we'd have the cars together, and they were ludicrously accommodating of us -- we'd be able to run the Civic Si and GTI virtually the entire day no matter what class was running at any particular time. And the course the Asebring Drivers had constructed in the parking lot of Qualcomm Stadium was nothing less than spectacular.
So Editor Edward Loh and Associate Senior Editor James Tate would drive the GTI down from Orange County while I came down from my house in Santa Barbara with the fresh sets of wheels and tires in the bed of my Toyota Tundra and the Civic Si on a U-Haul trailer behind it. And, incredibly, that all worked out and we found each other at about 10:00 a.m. that Sunday.
The western end of the Qualcomm Stadium lot has been used for Solo events from about the moment the city-owned stadium itself was opened back in 1967. In fact, the west lot seems almost designed for Solo with a gentle slope up towards its perimeter edge that adds an elevation change rare for a parking lot autocross course. Also, the lot is huge so the course laid out by Asebring that weekend was a long and relatively quick one; most curves had generous radii, the straights were long enough to build real speed, there were corners tight enough to demand good braking, and the surface was consistent and pretty grippy. In short, while it's not the Nrburgring, as far as autocrosses go, this one was about 1.1-mile's worth of glory. And it was a good test of both cars.
Our thanks go out to Charlie Bieri and everyone at Asebring for their generous hospitality and infinite patience.
The Civic Si, The GTI
Volkswagen decided the best way to achieve performance from its 2.0-liter four in the GTI was to cap its iron block with an aluminum, DOHC, 16-valve cylinder head and then plumb in a turbocharger to heave some boost into it. The result is a rated 200-horsepower at 5,100 rpm and a generous 207 lb-ft of peak torque at a stunning, is-it-a-diesel low, 1,800 rpm. In the test machine, it fed a six-speed manual transaxle, but VW's excellent Direct Shift Gearbox (DSG) six-speed automatic is offered as an option.
Honda, on the other hand, evoked entertaining power from its 2.0-liter four in the Civic Si by topping its aluminum block with an aluminum, DOHC, 16-valve cylinder head and equipping that head's valvetrain with the latest i-VTEC electronic variable valve timing and lift control. So the result is a rated 197-bhp at a screaming 7,800 rpm and a slight 139 lb-ft of peak torque at 6,200 rpm. If you're desperate to break past the 200-horsepower mark, your Honda dealer might suggest you buy and keep one of the company's 3.5hp EU2000i inverter generators in the trunk. The only transmission offered is a close-coupled six-speed manual.
