Lexus used the Australian International Motor Show to introduce the new IS 250 Sports Concept, in an attempt to beef up the sedan’s mediocre sporting credentials.

The concept features a number of performance oriented changes, some cosmetic and others more meaningful. Some of the main enhancements include larger cross-drilled two-piece brake rotors at front and rear, Bilstein shock absorbers and springs for improved handling, and the addition of sway bars and a chassis brace to improve the vehicle’s rigidity.

Under the hood, the concept features a performance air intake which boosts horsepower by 3% and a carbon fiber engine cover. The manual transmission is outfitted with a short shift kit which reduces shift effort by 35%, while the clutch delivers a 16% increase in clamping force for better pedal feel and increased power delivery. In the rear the IS 250 Sports Concept features a stainless steel "cat-back" exhaust system for a 1.5% increase in power and a better exhaust sound. Light weight 19” graphite grey wheels round out the key changes.

Lexus chief executive John Roca said that "The introduction of the IS 250 Sports Concept is still in preliminary stages but it's something we definitely want to investigate," he also stated that "The addition of the performance enhancements to the IS range would assist in attracting younger buyers to the Lexus brand - and give Lexus a vehicle that aspiring IS F customers could step into.” For now Lexus will concentrate on bringing the IS-F to Australia, but it seems possible a version of the IS 250 Sports Concept might see the light of day.
