The Lexus RX Hybrid is a hybrid crossover SUV sold by Lexus since 2005. The RX Hybrid uses the Lexus RX body design and a Lexus Hybrid Drive powertrain which combines a V6 gasoline engine with electrical motors.[1] First introduced in January 2004 at the North American International Auto Show, the original RX 400h became the first luxury hybrid,[1] and the world’s second mass-produced hybrid sport utility vehicle, after the Ford Escape Hybrid. The RX 400h was also the launch vehicle of the Lexus hybrid lineup, which later expanded to include hybrid versions of other Lexus vehicles, including the GS 450h and LS 600h/LS 600h L.

The first generation RX 400h was sold until the 2008 model year, and an equivalent model, the Toyota Harrier Hybrid, was sold in Japan until the same year. In November 2008, Lexus launched a complete redesign of its hybrid crossover, the second generation RX 450h, at the Greater Los Angeles Auto Show.[2] The Lexus RX 450h was scheduled to go on sale in North America, Europe, Asia (including Japan), and other markets in 2009 as a 2010 model.[2]

Lexus debuted the RX 400h at the North American International Auto Show in 2004, with plans to launch the vehicle in the U.S. market. The equivalent Harrier Hybrid debuted in Japan on 22 March 2005, the same day as the Toyota Highlander Hybrid. The Lexus RX 400h made its U.S. sales debut in mid-2005, with over 9,000 pre-orders at launch.[3] The RX 400h’s arrival in the U.S. had been delayed by several months; Lexus had announced in November 2004 that the American launch of the hybrid Lexus SUV would occur for the 2006 model year (with European and Asian launches during 2005).[4]

Since its launch, the all-wheel drive RX 400h/Harrier Hybrid has been sold at a substantial premium over the non-hybrid RX 300/RX 330/RX 350/Harrier.[5] In the U.S., the initial base price was US$49,185, which was a $5,600 premium over a similarly-equipped RX 330/RX 350.[1] A front-wheel drive version of the RX 400h debuted in 2006, with a base MSRP approximately $1,400 less than the all-wheel drive RX hybrid.[6] For 2007, along with the reduction of the federal hybrid tax credit for its hybrids, Lexus lowered the base price of the RX 400h to $42,580 and $41,180 for the respective all-wheel and front-wheel drive versions.[7] The list price in Japan for the Harrier Hybrid ranged from 4.095 million Yen to 4.62 million Yen.[8] Based on the 2010 Lexus RX redesign, no 2009 model for the Lexus RX 400h was offered.

The gasoline-powered part of the RX 400h engine system is a 3.3 L 3MZ-FE V6, very similar to the one found in the RX 330. It produced 211 hp JIS (155 kW) and 288 N·m (212 ft·lbf).[9] The gasoline engine is aided by a maximum of two additional electric motors, one driving the front wheels, producing 167 hp JIS (123 kW) and 333 N·m (245 ft·lbf) and connected to the CVT gearbox,[9] and the other driving the rear wheels, producing 68 hp JIS (50 kW) and 130 N·m (95 ft·lbf).[9] The whole system, called Lexus Hybrid Drive (also Hybrid Synergy Drive), produces a maximum of 272 hp JIS (200 kW).[9] With Lexus Hybrid Drive, under normal driving conditions, only the front motor and gasoline engine are used. The rear motor is only used under full-throttle acceleration or when the front wheels lose traction.[1] The gasoline engine switches off automatically and the car runs completely on electricity when either stationary, decelerating, or being driven at slow speeds (0 to 40 miles per hour).[1] An Ni-MH battery is responsible for powering the motors,[1] and is charged by generators during deceleration or sharp cornering.[5]
