The wait is over, Lexus unveiled the much anticipated HS 250h today at the Detroit Auto Show. There’s plenty to go over, but let’s start by breaking down the most noteworthy points about this new hybrid:
- The HS 250h sports Lexus’ first four-cylinder gas engine, a 2.4L Atkinson-cycle powerplant that generates 187HP.
- No exact fuel milage figures were released, but Lexus is claiming 30% better efficiency than the IS 250, which puts it over 30 MPG. Even better, the engine uses 87 octane gas.
- The new hybrid technology first seen on the new 2010 RX 450h will also be included on the HS, including the exhaust heat recovery system to reduce engine warmup time, an infrared reducing windshield that decreases the need for air conditioning, and the standard Lexus hybrid LED lights.
- Much of the HS’ exterior design is necessitated by the need for an extremely low drag co-efficient. Along with the highly optimized under-floor coverings and air passages, the roof panel, front spoiler, rear spoiler, rear under-spoiler and diffuser fins all contribute to the 0.27 Cd.
- The HS chassis features a MacPherson strut front suspension and a double-wishbone rear suspension, which gives excellent maneuverability, control and comfort.
- The HS’ interior utilizes eco-friendly bio-plastic, which emits less carbon dioxide over its lifetime.
- Like the 2010 RX, the HS will include the Remote Touch controller navigation interface, the Lexus Enform telematics service, Electronic Power Steering, the Heads-up Display, and a lane-keep assist system.
