Lexus introduces new model improvements across the Lexus IS range at Frankfurt Motor Show.

Adding a limited slip differential to the ultra-high performance IS F was something, which Lexus should do since they launched the IS F, but better late than never. The new differential mounted in IS F is Torsen type LSD capable of handling more than 500N/m. Still the power of the IS top performance model is 417bhp and 505Nm of torque put on the road through 8 speed Sports Direct Shift.

They also offer a new F-Sport trim package for the regular IS 250 and 220d models, and introduce DAB-ready audio and new Hard Disk Drive (HDD) navigation systems.The F-sport package includes front grille, rear spoiler and exclusive 18-inch alloy wheels. Interior features include IS F-style seats, steering wheel and, on the IS 250, automatic gear lever.

The option list includes three audio systems: two premium Lexus systems with six-CD changer, steering-wheel mounted controls and eight or 13 speakers; and a 14-speaker Mark Levinson Premium Surround Sound System, giving perfect 5.1-channel surround sound on compatible CDs and DVDs

The updated model range will be available to order in the UK from December this year.
