Japanese M3-fighter is being readied in open-top form.
Lexus did one heck of a job turning the IS sedan into the IS F performance machine. But the four-door isn't the only version of the IS. There's also a two-door hard-top convertible, and as these spy shots reveal, the premium brand from Toyota is planning to F it all up, too. Spied undergoing testing at the Nurburgring, this IS F cabrio is identifiable by its new front bumper, wider wheel arches packing larger stock and a massive rear wing (possibly used for testing purposes only). Also, by the very fact that it's at the Nurburgring altogether.
The IS F sedan features a 5.0-liter V8 with direct injection to deliver 416 horsepower to the rear wheels for a 4.6-second sprint to 62. Expect the convertible to mimic these numbers, but with two fewer doors and one big folding roof. That is, assuming Lexus doesn't follow Mercedes' lead by fixing the roof like AMG did with the SL65 Black Series.
