Bodystyle, dimensions and technical details

Although the IS-F shares its basic suspension with more mainstream IS models – double wishbone suspension at the front and a multi-link arrangement at the rear – Lexus has undertaken some serious tinkering to give the IS-F greater control.

The front suspension arms and steering knuckles are now constructed from lighter materials to reduce unsprung mass, the spring rates are increased, the anti-roll bars are thicker and the bump stops activate earlier, while the hub bearings are unique to the IS-F.

The IS-F looks better in the metal than in pictures

As expected for a sports model, the IS-F wears thicker and broader brakes (360mm at the front and 345mm at the rear), but unusually for a car with such driver-focused intentions, the IS-F employs electric power steering, and not a hydraulic system. 

On first inspection the driveline package seems familiar, the 5.0-litre V8 providing the conventional power in Lexus’s range-topping Lexus LS600h hybrid. The eight-speed automatic transmission has also been seen before in the LS460 and GS460. Make no mistake, though, there has been some major tweakery. The result is a maximum output of 417bhp, 28bhp more than the LS600h, although torque slips slightly to 372lb ft.

The automatic gearbox in the IS-F benefits from bespoke ratios and a manual mode, operated either by the gear selector or paddles mounted behind the steering wheel. From second gear upwards the ’box operates a lock-up mechanism to give faster shifts and a more direct throttle response. It will also hold on to gears right to the rev limiter and only change down if the engine threatens to stall.

Back to top

The IS-F has also undergone an extensive visual makeover. In addition to the beefed-up bumpers and bigger wheels (in this case 19-inch), the IS-F has a bonnet bulge that makes even the M3’s power dome look inadequate, broader sills and pumped-out front wheel arches complete with cooling gills.

The cooking IS has a particularly sleek shape, and these testosterone-fuelled changes aren’t entirely successful; in particular, the vertically stacked exhausts smack of Lexus trying too hard. Overall, though, the IS-F looks better in the metal than in pictures.
