The crew from Suzuki and Road & Track officially hold the new Land Speed Record for the Blown Gas Coupe Category. The team wheeled out their modified 2010 Suzuki Kizashi to the Bonneville Salt Flats and managed to average an impressive 203.720 mph across two high-speed runs, besting the previous record by a little less than a second and a half. R&T commissioned legendary engine builder Richard Holdener to rework the engine in the Kizashi before it hit the salt, and as a result, the car wore forged internals and a beefier turbo that shoved a full 16 pounds of boost into the four-cylinder as the Sam Mitani-helmed Suzuki headed down the dry lake bed.
Now that the Kizashi has one record under its belt, Road & Track is planning to try for a second, naturally-aspirated record by unbolting the turbo and going hog wild. Now all we have to wonder is how much it's going to take to convince Suzuki to offer those slick seam-welded steel wheels as an option on the Kizashi Sport. Hit the jump to take a look at a video of the car during its record-setting run, as well as a press release detailing the occasion.

WENDOVER, Utah (Aug. 18, 2010) – Piloting American Suzuki Motor Corporation's (ASMC) modified 2010 Suzuki Kizashi Bonneville Special, Road & Track's Sam Mitani injected the Kizashi into the record books (and himself in the 200 mph club) with his 203.720 mph run at this year's Bonneville Speed Week, exceeding the previous record of 202.301 mph. Despite a multitude of records – and record attempts – achieved by Suzuki motorcycle riders, this was the first official crack at the Bonneville Salt Flats by American Suzuki's automotive arm.
Conditions for the Kizashi's record-setting Bonneville run were exactly as the build team, Advanced Product Engineering's Richard Holdener, Tom Habrzyk and Scott Bailey, expected. With temperatures topping 100 degrees, the Kizashi was running at a density altitude on the flats of 6,303 feet. After passing inspection, the 2010 Kizashi provided Mitani, Road & Track's international editor, a perfect platform for qualifying with the Southern California Timing Association (SCTA), the sanctioning club for all Bonneville records. The 203.720 mph record was achieved by calculating the average of a two-way pass at 8:40 a.m. MT on August 18, 2010.
2010 Suzuki Kizashi Bonneville Special
Beginning with interior safety and instrument modifications, the Suzuki Kizashi Bonneville Special underwent additional refinements to make it salt-ready. Once the work was completed, the team installed the SCTA-approved roll cage, an aluminum bulkhead in the rear, racing seat, seat harnesses and window net. Next, it was time to take a look under the hood. The motor was disassembled to confirm the stock measurements, while the cylinder head was flowed and ported. The Kizashi Bonneville racer benefits from a new intake manifold, a tuned 'long tube' header and forged rods and pistons for high rpm endurance.
With up to 16 pounds of boost from a Turbonetics turbocharger, the Kizashi's increased horsepower required air-to-water intercooling (and snow water/methanol injection) – while its increased output demands a new ACT clutch and pressure plate. A scattershield is added, the oil pan is welded for a new drain fitting and a new 3.5-inch exhaust is fabricated aft of the turbocharger. Additional protection for the high-boost, high-rpm turbo motor is provided by full synthetic 5W-20 racing oil from Lucas Oil.
The Kizashi platform – and its Nurburgring heritage – is morphed into a salt-specific recipe with new coilovers, steel wheels seam welded, and speed-specific 15x7-inch Goodyear Front Runner® rubber. An air dam keeps the Kizashi's nose planted, window straps and hood pins ensure the hood and glass stay in place, and a parachute can bring the high speed show to a controlled and shortened stop. Finally, a dual fire system provides the extra assurance so important for Mitani, with more than 500 boosted horses but only a few feet in front of his high-speed capsule.
