Lexus is expanding choices in its popular IS sport sedan line for 2011, adding a 306-horsepower IS 350 all-wheel drive (AWD) model and offering a new F Sport Package for the IS 250/350 rear-wheel drive (RWD). Revised front and rear styling details sharpen all IS models for 2011. In addition, the IS sedans feature minor interior trim changes.
A new front grille and bumper distinguish the IS sport sedans for 2011, while at the rear, the models show a new taillamp cover and revised tailpipe design. New HID headlamps with LED daytime running lamps are standard on the IS 350 and available for the IS 250. Keeping with Lexus’ attention to detail, the 2011 IS models feature new-design standard 17-inch and optional 18-inch wheels, along with revised exterior color choices.
The IS 350 AWD model joins the IS 250 AWD, which has accounted for 30 percent (nationally) of IS 250 sales since the model’s introduction. Now, IS customers can have the traction and grip of all-wheel drive with the IS 350’s higher performance capability.
The IS 250’s 2.5-liter V6 engine delivers 204 horsepower at 6,400 RPM and 185 lb.-ft. of peak torque at 4,800 rpm. The IS 350’s 3.5-liter V6 offers a more potent 306 horsepower at 6,400 RPM and 277 lb.-ft. of torque at 4,800 rpm. The IS 350 RWD model can accelerate from zero-to-60 mph in just 5.3 seconds. Both engines employ dual Variable Valve Timing with intelligence (VVT-i), which controls timing on both the intake and exhaust camshafts.
Aside from its larger displacement, the 3.5-liter V6 also differs in that it augments the direct fuel injection with port fuel injectors. In light- and medium-load conditions, these additional injectors help produce a precise burn, optimizing power and efficiency. A dual exhaust system reduces backpressure at higher engine speeds.
An advanced six-speed automatic transmission with steering-wheel-mounted paddle shifters is standard on the IS 350 models and the IS 250 AWD. The IS 250 RWD comes standard with a crisp-shifting six-speed manual transmission, with the paddle-shift automatic offered as an option.
