The Lexus IS is a series of entry-level luxury cars / compact executive cars sold by Lexus since 1998. The IS was introduced as an entry-level sport model slotted below the ES in the Lexus lineup (and outside of North America, the Lexus GS). The Lexus IS F premiered at the 2007 North American International Auto Show on January 8, 2007 as the launch product of Lexus' F marque lineup of performance-focused vehicles.
For 2014, the IS 350 F Sport is powered by a 210 cu in (3.5 liter) engine which generates 306 HP @ 6400 rpm. The car is capable of 0–100 kph (0–62.1 mph) in 4.6 seconds, and has an electronically-limited top speed of 270 kph (170 mph). The IS 350 F Sport boasts an exclusive Adaptive Variable Suspension and is the first Lexus to vary shifting with G-forces. By detecting when the car enters a curve, a lower gear is held throughout for optimal response when accelerating out. And, when pushed to higher rpm, the IS 350 F SPORT is filled with a throaty engine note that complements the exhilarating performance of the vehicle.
