The Lexus RX comes in two basic forms: RX 350 and RX 450h. The RX 350 is powered by a smooth 3.5L V6 engine and produces 295 horsepower. With this engine, 60 mph arrives in under eight seconds, and the RX 350 achieves 28 mpg on the highway in front-wheel drive trim. The RX 450h combines a traditional gasoline engine with an electric motor for a total of 308 horsepower. Highway fuel economy climbs as high as 30 mpg for the front-wheel-drive models. The only transmission available is an 8-speed automatic, and all-wheel drive is optional on either version of the RX. Both the RX 350 and the RX 450h are also available in F SPORT guise, further enhancing both the interior and exterior styling, while also tightening up the handling. The F SPORT package adds an 8-inch LCD display instrument cluster, unique quilted seats, adjustable suspension, interior aluminum trim accents and drilled aluminum pedals. Outside, the F SPORT gets a blacked-out grill, plus exclusive 20-inch wheels. Option packages available on the RX 350 include a Luxury Package with perforated leather seats, a nicer powered driver's seat, 20-inch wheels, a heated steering wheel and Gray Sapele wood trim. A Navigation Package adds a 12.3-inch color screen for the navigation system, a 15-speaker Mark Levinson sound system, voice command, a DVD player, dual-zone climate control and Lexus Enform app suite. A Lexus Safety System package includes a pre-collision system with pedestrian detection, dynamic radar controlled cruise control, a lane-keep assist and lane departure warning system, intelligent high beam headlights and premium triple beam LED headlights.
