Short Take Road Test
Why the letter "F" in the new V-8-powered, 416-horsepower Lexus IS F? Simple: Toyota's luxury brand and the letter F have a long history. In the mid-1980s, the Lexus luxury division was then just a classified notepad document codenamed "Circle F." The first Lexus LS400 of 1989 was known internally as the "F1" or "Flagship." And the stylized Fs on the 2008 IS F are drawn, it's said, to mimic a few hairpin turns of Toyota's Higashi-Fuji test track.
This first F (there'll be more Lexus models with the F treatment soon, most likely) is a V-8-powered sledgehammer that rockets to 60 mph in 4.2 seconds—fleeter by 0.1 second than the new M3—has a 172-mph speed governor, and generates 0.92 g on the skidpad. It also keeps us grinning through hard track laps, even though the frequent fill-ups of premium were inhaled by street driving at the rate of 16 mpg. We'll have to wait until March, 2008, when the IS F goes on sale at an expected price around $59,000 to see how many buyers are interested in a wicked-performing Lexus.
Developed in cooperation with Yamaha, the IS F's engine, or the 2UR-GSE as Toyota calls the 416-hp variant of the 389-hp 5.0-liter V-8 found in the LS600h hybrid, sans hybrid gear, is peakier, actually losing 17 pound-feet of torque on the operating table as the changes pushed the horsepower and torque peak higher up the revs. Solid lifters and titanium intake valves with 10 percent more lift reside in new higher-flow cylinder heads. At full throttle above 3400 rpm, a barn door in the box snaps open with vacuum released from a small reservoir, and the unleashed induction noise is raw and thrilling.
Polished paddles put your fingers in charge when you wish it. And they'll be busy, the swift-revving engine and ratio-stuffed, eight-speed automatic gearbox bringing forth the redline cutoff with annoying frequency. With all that engine fettling, the warning beep reminding you to upshift at 6400 rpm and the cut-out at 6800 rpm feel a bit low. The new 414-hp BMW M3's engine screams all the way to 8400 rpm.
Despite the bling of braided-aluminum trim on the doors and shifter console, temperance rules indoors. Blue-lit gauges and blue seat stitching, alloy pedals, a digital gear-position display, and the subtle F logo on the wheel are the differentiators that drivers see. The base car's rear bench is divided in the IS F into two non-folding buckets with a ski pass-through.
At leisure speeds, the air is hushed, Lexus-like, with just a distant snort from the engine and the extra thrum of the fat summer Michelins disturbing the peace. Given the low profile of the rubber mounted to the 19-inch forged aluminum rims, the ride is tightly controlled but commendably mellow. The ride-and-handling balance is perhaps the IS F's biggest achievement. It makes allowances for road fissures and drops the body into holes with cushioned lurches.
It also permits the 3800-pound car some restrained roll through the esses but not enough to wither confidence. The IS F's steering rack accurately puts tires where they're needed and provides talk-back, albeit faint, on how things are holding. And hold they do, with excellent grip.
The all-important sport button also perks up throttle response and relaxes the stability-control system to allow some controlled tail-out action. Lexus also allows you to shut the system completely off, but the shutdown can only be called for while at full stop. Brembo-sourced front calipers on broad cross-drilled rotors deliver solid braking but with a soft pedal.
The muted interior, the slightly watery controls, the heavy price tag; the IS F is at core a Lexus with extra muscle, not as raw as the BMW M3 or Mercedes C63 AMG. The next steps for F may decide if the performance sub-brand thrives or is only a brief experiment.
