About Lexus RX 450H
For the third iteration released in 2009, both RX 350 (3.5-liter V6) and RX 450h (3.5-liter V6 hybrid) models were initially offered, with an entry-level RX 270 (2.7-liter inline-four) offered by Lexus in some Asian markets, including in Japan, since 2010.
The RX 400h served as 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, and in 2009, the first ever designated-hybrid (no gasoline model available) Lexus, the HS 250h.
On 9 October 2007 design patents were filed at the Japanese Patent Office (7 April 2008 in the U.S.) for both a conceptual variant and two production variants (RX and RX 450h).
Introduced in 2009 as a 2010 model year vehicle, the RX 450h (GLV10/GLV15) premiered alongside its non-hybrid counterpart, the RX 350.
Manufacturer’s specifications indicated largely identical outward dimensions for the RX 450h with the RX 350. The RX 450h was scheduled to go on sale in the U.S. in mid to late 2009, with sales introductions for the RX 450h in Asia (including Japan) and Europe in the same year.
The RX 450h features an upgraded 3.5 L 2GR-FXE V6 engine (shared with the RX 350) which produces 245 hp (183 kW) at 6000 rpm, along with a new inverter which boosts total horsepower to 297 hp (221 kW) (with the electric motors providing an added 22 hp (16 kW)). The new inverter is 8 kg lighter, and more efficient.
Up to three electric motors are used in the hybrid system, including two dual motors for the forward wheels (123 kW output), and a third for the rear wheels on the AWD model (50 kW; engages when slippage is detected or the throttle pressed firmly). The RX 450h’s V6 engine now runs on the Atkinson cycle for added efficiency. Compared to the prior Otto cycle system, the Atkinson cycle has a lower compression ratio, along with higher expansion ratio inside engine cylinders.
This system uses less energy to form fuel-air mixtures, and releases more energy. A lighter, more free-flowing oil (0W-20) is also used, reducing friction energy loss and oil pump power requirements. Two additional systems are added to the RX 450h’s Lexus Hybrid Drive powertrain, an exhaust heat recovery system to reduce engine warm-up periods (optimizing engine start-stop times, particularly in cold conditions), and a cooled exhaust gas-recirculation system to reduce fuel pumping loss. The electric motors use the first automotive application of liquid cooling on both sides of the high-current transistors, allowing greater contribution from the electric motors versus the gasoline engine.
Sales began worldwide in April 2012 for the RX 350 and RX 450h, with sales for the F-Sport variants starting in July of the same year.
This is mated to an 8-speed automatic transmission. The gasoline engine and electric motor RX 450h hybrid also reach a combined power of 308 hp (230 kW).
The release of the RX in the United States was scheduled for November 2015. For the first time in the U.S. market, Lexus released an F Sport version of the RX hybrid, the RX 450h F Sport.
In November 2017, Lexus announced new three-row seven-passenger models of the RX, the RX 350 L and RX 450h L. They are 11 cm (4.3 in) longer than the two-row model but have the same wheelbase.
As of April 2015, Lexus had accumulated more than 2.1 million RX models worldwide. The Lexus RX 400h/RX 450h is the top selling Lexus hybrid, with global sales of 335,000 units through March 2016, out of one million Lexus hybrids sold worldwide.
