Given the IS-F's multiple transmission (manual or automatic) and VDIM (regular, sport and off) modes, I asked Flynn how the car would be "configured" for our ride, and he informed us it would be "manual" transmission mode and the intermediate VDIM Sport mode.

Lexus Gets Tough

It's as if the New York Philharmonic added an "An Evening of Kanye West" to its concert season. Though Lexus has always carefully presented itself as the jewel of the Toyota empire, it's preparing to jettison two decades of heritage with the 2008 Lexus IS-F, a tough-looking car fortified with a 400-horsepower V8 that will challenge the Audi RS4 and BMW M3.

It's the most surprising thing Toyota's luxury division has done since hiring actor James Sloyan to purr out words like "relentless," "pursuit" and "perfection" back in 1989 before it had even sold a single car.

The formula for the IS-F couldn't be more straightforward or familiar: Just shove the biggest engine possible into a relatively small package. It worked for the 1964 Pontiac GTO and it's working right now for the E92 BMW M3, and there's no reason why it shouldn't work spectacularly well for Lexus, too.

Block-by-Block Performance
While the conceptual audacity of the IS-F is shocking, most of the car's engineering is related to familiar Lexus stuff.

All current U.S.-market IS-series sedans are V6-powered (a 204-horsepower 2.5-liter V6 motivates the IS 250 and a 306-hp 3.5-liter V6 does the job in the IS 350), yet the IS is essentially a cut-down version of the larger GS sedan. And since a 4.6-liter V8 is the indispensable ingredient of the 2008 GS 460, Lexus didn't have to perform major surgery to squeeze a V8 into this rear-wheel-drive IS sedan.

Lexus also has a suitable engine for a hot-rod IS already in its parts inventory, as the hybrid drivetrain in the LS 600h L features an all-aluminum 32-valve, DOHC 5.0-liter V8. Even in the relatively sedate LS, this engine is rated at 389 hp at 6,400 rpm and 385 pound-feet of torque at 4,000 rpm and incorporates such advanced technologies as direct injection and dual variable valve timing working with an electronically controlled intake (VVT-iE in Lexus-speak).

Though Lexus is still coy with us about the specifications of the IS-F's V8 as the date of the car's introduction approaches, the engine is almost certainly based on the LS 600h L's 5.0-liter V8. And it won't take much more than a few tweaks to the variable valve timing system and the engine management electronics to boost this power plant's output to the "400-plus" hp that's been promised in the IS-F.

Eight Speeds, No Waiting
Meanwhile, the IS-F's eight-speed "direct sport-shift" transmission is also apparently based on an LS-series component — the eight-speed automatic transmission that was introduced by the LS 460 at the car's introduction in 2007.

The IS-F's version of the eight-speed unit features a new torque converter that locks up in 2nd through 6th gears even while in automatic mode. In manual mode, Lexus promises the shift paddles mounted on the steering wheel will trigger shifts in less than a tenth of a second, while downshifts will be accompanied by computer-automated throttle blips to match engine and transmission speeds.

With plenty of power and eight gear ratios, Lexus is claiming a 0-60-mph time of "less than 4.9 seconds" for the IS-F. We're guessing that it will be a lot less than 4.9 seconds, since this number has already been achieved by the 2007 BMW 335i automatic.

After all, Lexus isn't aiming at the BMW 335i with the IS-F. It's hunting the M3.

Fortified Stability
In general specification, the IS-F's suspension is just like that of any other IS sedan. There are double wishbones behind each front wheel, and a multilink independent system in back. But virtually all the IS-F's underpinnings have been reinforced for high-performance duty.

Naturally the suspension calibration is firmer, but it's also an inch lower than in other IS models and tuned so the big 225/40R19 front and 255/35R19 rear tires can grab pavement with some ferocity. The tires are mounted on special forged-alloy BBS wheels.

When it's time to throw out the anchor at speed, Lexus has fit the IS-F with big 14.2-inch front and 13.6-inch rear disc brakes. The front discs get six-piston Brembo calipers while the rears get two-piston Brembo units.

Lexus has also programmed a "three-mode" version of its Vehicle Dynamics Integrated Management (VDIM) stability control system. Once you step up from Normal mode, the Sport mode raises the threshold at which braking, steering and throttle intervention kick in. The third mode? This may be the best of all; Lexus calls it "Off."

The Meanest Lexus Ever
With its uniquely stacked quad exhausts and rear spoiler, the IS-F's rear treatment makes sure you won't mistake it for any pokey IS 250 or IS 350. But the most distinctive elements of the IS-F are up on the nose.

The hood bulges to cover the big engine, the front fascia drops down to feed air to the beast and the fenders flare to cover the wide tires. There's never been a Lexus with the menacing presence of this one. In fact, the IS-F is the anti-Lexus.

Once you climb inside the IS-F, on the other hand, you return to a more familiar Lexus environment, although there's plenty of aluminum trim and a bold "F" prominently featured on the steering wheel and the console between the twin rear seats. Naturally the pedals have aluminum covers. The seats have been shaped for aggressive driving and will be upholstered in either black or white with black trim. The instrumentation includes an oil temperature gauge and shift indicator light.

This will be the top-of-the-line IS, and there's no way Lexus is going to walk away from its tradition of comfort with this car. After all, even the meanest badass Lexus of them all must still be a Lexus.

Anticipation
With the new 2008 BMW M3 with its 400-hp V8 about to go on sale in the U.S., the message boards on the Internet have been ablaze with speculation about whether the IS-F will give the BMW a real run for the money. After all, no car has a more fanatic following than the M3 and no car has gone so long without being toppled from atop its niche.

On paper the 2008 Lexus IS-F stacks up well against the M3, not to mention the Audi RS4 and Mercedes-Benz C63 AMG. In the metal, the IS-F's appearance is polarizing ("F stands for FUGLY! The car looks wack," said Juzef on an M3 message board we surfed recently), and much of the criticism centers on the car's bulging hood and distinctive fenders. The IS-F's big nose might make this car an icon or a joke. This will depend in large part on how it performs.

As Lexus is already telling us in its advertising, "'F' is everything you thought we weren't." It's right about that. But this is a risk the division needs to take if it's going to maintain its performance credentials against the likes of BMW, Mercedes and even the recently surging Infiniti. And Lexus must be serious, because it's going to push even further into unknown territory with its 2009 Lexus LF-A, a super sports car with a 500-hp V10.

Lexus has an unparalleled reputation for quality. Imagine what can happen if this character is paired with dynamic excellence and blistering performance. The mind boggles and the cash registers ring.

The 2008 IS-F goes on sale just as 2007 runs out.

Can Lexus Take Down the Germans Again?
By Daniel Pund, Senior Editor, Detroit Email

With the introduction of the 2009 Lexus IS-F, it's supposed to be 1989 all over again.

That was the year that Toyota dared to take on the established German luxury carmakers with its brand-new luxury division, Lexus. And it was also the year that the Lexus LS 400 sedan's immediate success embarrassed those German luxury carmakers into dramatically improving their quality, their customer service and even their prices.

Lexus would like you to believe that the 416-horsepower IS-F will have a similar impact on the market for over-endowed hot-rod sedans that is dominated by (you guessed it) the Germans. The "F" suffix for this new variant of the IS is a nod to the early days of Lexus, when "F1" became the code designation for the LS 400 prototype.

But Wait Just a Minute There
Don't don your bomber jacket, crank up the Whitesnake and pretend it's 1989 just yet. There's the small matter of those three German sedans, each of which makes around the same 400-plus horsepower as the IS-F.

To put the $60,000 2009 Lexus IS-F to the test, we rounded up one of our favorite German über-sedans, the Audi RS4. We left out the BMW M3 partly because it is only currently offered as a two-door and also because it hasn't, you know, actually been formally introduced to the U.S. yet. And the same goes for the Mercedes-Benz C63 AMG.

For now, though, it is a battle between the bulked-up, slammed-down Lexus IS-F and the Audi RS4, the all-wheel-drive A4 with a 420-hp V8 that we recently described as "The Best Driving Audi Ever."

Freaky Styley
Unfortunately, before you can take a seat behind the wheel of the Lexus IS-F, you have to, you know, see it. We accept that the question of styling is largely a subjective matter. So there might be some Toyota fanboys who will admire the IS-F's nose — so like that of a Beluga whale. They might even like the dewlaplike growths behind the front wheels. But no one of sound mind could love the stacked quad exhaust tips. This is at least partly because they are not actually exhaust tips. In fact, they are not connected to the exhaust system in any way. They are simply jewelry for the rear fascia. It's an uncharacteristically cheesy execution by Lexus.

Yet when you see it slammed down almost an inch on 19-inch anthracite-finish BBS wheels, the spokes of which look like a pinwheel of razor-sharp chef's knives, the IS-F is sufficiently menacing. Glinting behind the wheels you'll find drilled and vented brake rotors with Brembo calipers. At 14.2 inches in diameter, the front rotors are slightly larger than a large Domino's pizza, while the rears are only about a half-inch smaller.

Where the IS-F has a certain look that we associate with the worst excesses of the aftermarket, the Audi is all understated musculature. It's relatively subtle, but we like it. Wide 19-inch wheels and tires are covered (barely) by dramatically flared fenders. And the special trunk lid has the sweetest ducktail spoiler formed into the metal. A lower ride height, satin-finish metal trim, a deeper front fascia and gorgeous wheels round out the RS4's visual signifiers.

The Inside Lines
Audi carries the same subtlety into the interior of the RS4. The seats are unique to the RS4, and they combine stellar support and comfort. This car also arrived with glossy strips of decorative carbon-fiber interior trim. (Brushed aluminum is also available but isn't as fast as carbon fiber.) Our test vehicle didn't come with the optional navigation system to confuse passengers or the memory-function seats to comfort them. It is what you might call a stripper if you can ever call a $68,875 car a stripper.

The poor bastards you cram in the backseat of the RS4 will become intimately acquainted with the meaning of "compact sedan" and also with each other, because the Audi rides on a 104.3-inch wheelbase that doesn't leave much legroom for those in the rear. At the same time, the rear-seat passengers for the Lexus IS-F are no more comfortable despite a wheelbase that's 3 inches longer. The Lexus seems more sporty because the rear seat accommodates only two passengers in quasi-buckets separated by an armrest, while the Audi is more practical, with three seatbelts in place on a conventional bench.

The IS-F's interior is a bit flashier than that of the austere German. Start it up and the blue needles for the tachometer and speedometer spin while a little "F" logo materializes between them. The almost-white woven-metal trim is a little showy for our taste, and the IS-F is seemingly always binging or beeping while in operation.

All Motor
Lexus could have just dropped its standard 4.6-liter V8 into the nose of the IS nose and made an easy 350 hp. Instead, the company started with the 5.0-liter V8 that is the gas-burning portion of the LS 600h powertrain. In the IS-F, the 5.0-liter makes 416 hp and 371 pound-feet of torque.

To get such power, Lexus threw everything it has at this engine. It's got titanium intake valves. It's got a water-cooled oil-cooler. It's got hollow camshafts. It's got direct injection and port injection. Hell, even the center shaft of the throttle butterfly is 3 millimeters narrower to permit incrementally better airflow when the butterfly is open.

You'll really notice the dual air intake. At low speeds, the engine breathes discreetly through the primary inlet. At engine speeds of 3,600 rpm or greater, a secondary valve opens and draws air from the right wheelwell. When that secondary air intake opens, it's as if the fine coffee you normally drink has been secretly replaced with nitromethane. The intake howl sounds fantastic and makes the IS-F feel quicker than it really is.

We wish only that Lexus could have given the engine note south of 3,600 rpm a little whiff of that high-rpm fury. Around town, only a faint rumble differentiates the IS-F's V8 from lesser Lexus motors, and you don't have any sense of the beast waiting on the right side of the tachometer.

Audi's 420-hp 4.2-liter V8 makes up for its displacement deficit with high revs, and it will constantly remind you why you write such a big check every month. It has the finest exhaust note on the market today, and the tone never wavers. There are no pronounced bursts of power in the Audi's curve; instead there's power everywhere.

Speed Shifting
If the IS-F's engine seems complicated, get a load of its one transmission offering. This eight-speed automatic is adapted from the tranny in the LS luxo barge.

Leave the shifter in fully automatic mode and you can never quite shake the impression that there are three too many gears in the box. It seems to always be lounging around in 7th on the highway and dithering among its many gears around town. Downshifts are slow to come. When it finally finds a nice low gear, the engine is spinning wildly, the engine note has turned angry and you've got more power than you asked for, plus it arrives later than you wanted it. Use the automatic mode only for traffic jams.

It's better to leave the transmission in manual mode and use the steering-column-mounted shift paddles to choose from the myriad gears. In all but 1st gear, this transmission uses a lock-up clutch to connect the engine and transmission, something like a conventional manual powertrain. When you combine the crisp feeling of engine response that results with tremendously quick upshifts and downshifts (with automatic throttle blips), the complex transmission becomes one of the most entertaining sequential-shift automatics.

The RS4 is offered only with a six-speed manual. Turns out, for a dedicated high-performance car, that old gearlever-and-clutch-pedal thing is still the way to go.

Numbers Don't (Often) Lie
Even with the roughly 70 pounds of extra weight that it carries, the 3,848-pound Audi is the quicker of these two cars.

Try this with your friend's RS4. At full stop, engage 1st gear, keep the clutch depressed and push the accelerator pedal until the tachometer registers 5,500 rpm. Then remove your foot from the clutch. All four wheels spin for a moment and then the RS4 digs its claws into the pavement and catapults forward to 60 mph in 4.3 seconds and on through the quarter-mile in 12.8 seconds at 108.5 mph. The all-wheel-drive Lamborghini Gallardo posts better numbers, but not by much.

The 3,780-pound IS-F gets to 60 mph in 4.8 seconds and does the quarter-mile in 13.2 seconds at 109 mph, trailing the RS4 to 60 mph by about a half-second and to the quarter-mile by almost as much. This is with the stability and traction control systems off (yes, Lexus actually allows such a thing, a policy initiated for its performance cars for 2007) and the transmission in Drive. Later we made our runs and manually shifted the IS-F's transmission, which feels fast but predictably isn't, especially since the launch is better in Drive.

Not that it matters. For all its displacement, technology and furious bark, the Lexus 5.0-liter doesn't make the IS-F much quicker than a BMW 335i, which makes 116 hp less.

Both cars stop with tremendous force and stability in a commendably short distance, with the Lexus coming to a halt from 60 mph in 112 feet and the Audi doing the job in 117 feet.

The Real Road and Track
The Lexus generates an impressive 0.93g of grip on the skid pad with its Michelin Pilot Sport PS2 tires, significantly more than the Audi's 0.89g on its Continental ContiSport Contact3 rubber. Despite this, the RS4 barrels through the slalom fractionally faster at 70.5 mph to the IS-F's 70.2 mph. Give some credit here to the Audi's super-quick steering ratio and some blame to the IS-F's tail, which according to one understated tester, "gets pretty lively."

For all their similarities, including the near-identical performance in the slalom, these two cars go about their business in opposite ways. And neither acts quite like you might expect it to.

According to tradition, the Audi should lack steering feel thanks to its all-wheel-drive system. It should understeer heavily as it gets led around by its heavy nose. And it should exhibit a flinty ride. Yet the Audi has the more communicative steering here. Its cornering attitude is surprisingly neutral. And its compromise between a comfortable ride and good handling ranks with the best that BMW has accomplished over the years.

The Lexus should be the one with the plusher ride, the less treacherous handling and the more intrusive safety net of electronic gizmos. Wrong again. Front spring and damper rates are up a whopping 90 percent compared to the standard IS, and the rear rates are 50 percent firmer. This is a stiff car — so stiff over freeway undulations that it forces small, involuntary exhalations from its passengers. One of us even knocked his noggin into the headliner, badly mussing his hair.

The World We Live In
The 2009 Lexus IS-F is the kind of car that really benefits from switching off the stability control, as it'll do some really wicked powerslides. And the IS-F handles really nicely and precisely. It's just too much for us, though. Too much to look at, too intricate to fully appreciate and too hard-core for the street.

The all-wheel-drive 2007 Audi RS4 just plain hauls ass. It doesn't rotate around an apex like a rear-driver. It's less the rapier than it is the broadsword. But it's devastatingly effective as a street machine, so it wins.

So it's not 1989, but it might just be the good old days anyway.

For all its displacement, technology and furious bark, the Lexus 5.0-liter doesn't make the IS-F much quicker than a BMW 335i, which makes 116 hp less.
