The aftermarket put some more heat in Suzuki's hot hatch

When we think of production vehicles that can double as daily drivers and weekend racers, the Lotus Exige, Mazda MX-5 Miata and Porsche Boxster come to mind. They've got to be light, nimble and handle the rigors of the road along with the demands of the track. That's why we had a little chuckle when a 2010 Suzuki SX4 with "Road Race modifications" came up on our schedule for vehicles to review. When we drove the 2008 SX4 Sport, we found it to have a "sporty feel and rather quick reflexes," but the chassis had fairly low limits and we couldn't imagine the squat hatch being that much fun on track.

Still, we were curious how a hopped-up SX4 would perform, particularly in 2010 MY guise, which adds seven additional horsepower (143 to 150 hp) and a six-speed manual transmission. Suzuki has billed its new five-door as a worthy competitor to the world's best hot hatches, but can it really deliver a world-class combination of practicality and sportiness? With several days of Southern California's back roads marked down on our schedule, we aimed to find out.

Before we get into the nitty-gritty, it might be pertinent to give some background on RoadRace Motorsports, the company that built this SX4 Sport. Based in Southern California, RRM made a name for itself building high performance Mitsubishi models, in particular the Lancer Evolution. In the last few years, RRM has turned its attention to Suzuki, developing a line of performance parts for the SX4 and Kizashi, and building several project cars including this particular hatch. Its parts catalog includes everything from carbon fiber aero parts to turbocharger systems.

The SX4 Sport looks the part, complete with a Vivid Red paint job and an aftermarket stripe kit ($149 from RRM) that even includes a blank roundel for a car number. It's a little too boy racer for street use, but it speaks volumes about RoadRace's confidence in its hotted-up SX4.

Even without the stripes, the SportBack is quite the looker from the factory. Gone is the roof rack from the SX4 Crossover, while a new front spoiler, side skirts and roof-mounted spoiler round out the exterior mods. The suspension has been lowered 15mm all around and a set of attractive 10-spoke, 17-inch wheels replace the rather bland factory 16-inchers. The result is a racy five-door that wouldn't look (completely) out of place when lined-up alongside Europe's best hot hatches.

The interior of the SX4 SportBack is by no means luxurious, but provides a no-nonsense environment with a refreshingly simple design. There are hard plastics on the dash and doors, but they don't feel offensive to the touch and manage to still appear fairly attractive. The seats are made of soft cloth and are comfortable, offering nice back support, while the thick steering wheel is comfortable to grip and houses only the most necessary buttons (volume, cruise, etc.). The center stack is laid out in the traditional and intuitive way, with the CD/AM/FM/XM controls above and climate controls below. A no-cost pop-up nav system rises from the top of the dash, and while it doesn't look as fancy as in-dash units, it gets the job done with a simple touchscreen. There are also some nice touches that make the cockpit feel a little more upscale, specifically the aluminum pedals with the Suzuki logo and handsome black gauges with white lettering and red and blue accents.

We expect quite a bit of convenience from a modern hot hatch, and the SX4 SportBack didn't disappoint. There's decent leg room for rear seat passengers, although anyone north of six feet tall probably wouldn't want to commit to a road trip in the back seat. The rear cargo area also offers a good amount of storage space, and the rear seats can fold 60/40 to make room for larger items.

The 2010 SX4 SportBack powers the front wheels with an updated version of its 16-valve DOHC 2.0-liter inline-four producing 150 horsepower and 140 pound-feet torque, up from 143 hp and 136 lb-ft the previous year. It's not a huge increase, but at such modest levels, every little bit helps. Our specially equipped car also came with an open-element air intake ($199), ECU upgrade ($399) and a freer-flowing exhaust, so we're guessing it had a slightly higher output than stock. The majority of the time, the peppy four-pot provided enough motivation to get going in a reasonably quick manner, especially in low speeds around town. The motor builds towards redline without a fall-off in power, although it lacks gusto even on slight inclines, especially below 3,000 rpm.

Also new for 2010 is a six-speed transmission and the option of a CVT with both a console-mounted gear selector and paddle shifters. The extra gear helps improve fuel economy, and the SportBack is rated at 22/30 for the manual and 23/30 for the CVT. Thankfully, our tester was equipped with the standard transmission, which provided nice, accurate shifts, with just the slightest hint of notchiness. Over our time with the car, we found that the SX4 responded better to aggressive shifting, and we actually enjoyed banging from one gear to the next. The only issue we ran into was an overly touchy throttle that made it quite difficult to get the car going smoothly from first gear.

The Sportback comes equipped with a MacPherson suspension in front with a rear torsion beam out back, and RoadRace Motorsports first order of business was to fit a sport suspension ($499) and a set of ultra-sticky Dunlop Direzza Sport Z1 215/45R17 tires ($528). The result: boatloads of grip. The spunky front-wheel-drive hatch continually surprised us with its ability to tackle even the most challenging corners with ease. Body roll is nearly absent, and a flick of the steering wheel directed the wheels with precision.

The modified suspension did come with a downside – a big one. The suspension is so stiff that it almost made the SX4 undrivable on even slightly rough roads. Going over bumps would often cause un-elicited grunts and groans, and at one point, the dash-mounted navigation system sprung open over a particularly rough section of road. While we had fun with the car driving up and down the canyons, it made day-to-day tasks nearly unlivable, all of which made us question how well RoadRace balanced the "Road" and the "Race" missions in the SX4.

Putting performance parts on a budget hatch like the SX4 SportBack might have worked in the early '00s, but as tuners and compacts have gotten more refined, drivers are expecting a better balance. Couple that with a base price tag of $17,999 (plus $795 in destination charges) and it's obvious the SX4 will mainly appeal to budget-minded buyers looking for convenience and a dose of sport in their daily driver. The modified suspension on our tester made it impractical as a daily driver, and yet, it's far from a dedicated track toy.

That said, we can see plenty of buyers picking up a stock SX4 for its endearing qualities that comes straight from the factory. The 2.0-liter engine is spunky if not sporty, and the new transmissions now provide respectable fuel economy. In all honesty, we'd probably suggest buying the SX4 Crossover model instead, as not only does it present a more capable – and unique – ownership proposition with all-wheel drive, it's also inexplicably and substantially cheaper at $15,899. That said, Suzuki has packaged the SportBack with an eye-catching exterior and attractive interior that makes it something of a bargain on appearance alone. But when it comes to modifications, we'd advise swapping on some new rubber and leaving the wrenches tucked away in the drawer.
