More technology gadgets but less driver distraction

Horrific blind

No towing capacity

The new generation RX blends the geekiness of high with the green consciousness of a hybrid car. Launched in the of 2009 as a successor to the RX 400h, new RX 450h builds on the success of the first luxury hybrid Visually similar to the RX 350, the has a few of its own unique styling features, an exclusive grille, hybrid with blue-trimmed Lexus unique front bumper, 19-inch wheels, blue-tinted and taillamps, and optional LED headlamps.

Exterior Styling

Toyota it safe with the Lexus You have to look really to catch the differences between the new and generation RX hybrid. The RX 450h is rounded and bubbly than its It’s also a bit wider and to sit lower on the road, but that’s because of its headlight placement and sculpting.

From the front, the RX looks bolder and stronger, but elegant.

The RX 450h’s profile is similar to the RX The roof-mounted spoiler is a bit stronger and the rear wiper, and Lexus has a small “shark-fin” antenna. The handles are now body-colored, but there’s new trim around the windows and the door bottoms.

There’s a discreet hybrid badge sits near the lower strip.

Beneath the Sheetmetal

The Lexus RX 450h enhances its ride and cabin with a power train that fuel economy unheard of for an The hybrid-specific, 2GR-FXE version of the V6 resembles the revised V6 featured in the Lexus RX 350, but it has higher (12.5:1 instead of 10.8:1) and on the fuel-saving Atkinson cycle. its variable valve timing only on the intake side.

The Atkinson cycle keeps the valves open during of the compression …, so this V6 just 245 horsepower at 6,000 rpm and 234 of torque at 4,800 rpm, the conventional version of this V6 275 hp and 257 lb-ft of torque. In short, is a significant increase over the V6#8242;s 208 hp and 212 lb-ft of torque.

The RX also draws power its 37-kilowatt, nickel-metal hydride pack to power the h-model#8217;s motors (a 123-kW electric for the front-wheel-drive RX and an additional rear motor for the all-wheel-drive RX). The pack provides 50 hp, giving the Lexus RX 450h a rating of 295 hp up from the 268 hp of the RX 400h. In operation, is an almost seamless transition the electric motors and ICE.

Perhaps this is the result of the mechanism to absorb torque the Lexus engineers have to the transaxle#8217;s flywheel damper.

We that the battery pack is for fewer kilowatts in the RX 450h; the RX battery pack had a 45-kW Don#8217;t let the numbers mislead The 2010 RX 450h actually more power out of its battery due to an improved cooling system for the and converters — it#8217;s the same used on the Lexus LS 600h L.

power from engine and motor is rated at 295 horsepower, a short of a V-8, while economy gets an EPA-rated 32 mpg and 28 mpg highway. Our ballistic driving netted us 28 mpg overall, a figure many four cylinder would have trouble

Driving Impressions

Acceleration was for a hybrid SUV vehicle weighing 4800 pounds and there was trouble accelerating up to high on the highway, thanks to the capable V6 Likewise braking was responsive, it had a strangely different feel to the regenerative braking features.

The also features a new, designed double-wishbone rear that helps provide agility and control. Its distinctive also allows for five more cargo volume and loading. To complement the new rear and provide excellent dexterity and comfort, the front McPherson geometry was optimized.

The suspension did turns very well, but the was that it just did not perform when absorbing large bumps.

As for the feel of the vehicle, its comfortable and spacious.  The steering retracts when you#8217;re not a nice touch.  The drive is smooth and NVH (noise, vibration, and is not overly high, thanks in to the smooth electric motors.
