Crossing over to green

The 2010 Lexus RX 450h poses a real dilemma for buyers.

On the one hand, it’s a hybrid, so that makes it one of the greenest of crossovers and the darling of environmentalists everywhere. On the other hand, our test vehicle – a top-of-the-line 450h with Ultra Premium Package – costs $72,000, $9,300 more than a comparably equipped RX 350 with its gasoline-only V6 engine.

So you’ve got to ask yourself if the extra cost of a hybrid is worth it. After all, any of today’s new vehicles sends far less pollutants out the tailpipe than ever before.

Nor is the RX 450h as fuel efficient as the numbers on the window sticker might lead you to believe.

It’s no secret that Transport Canada’s fuel economy figures are almost impossible to attain in real world driving. But they’re wildly out of line in the 450h. In fact, the 9.4 L/100 km I achieved on a tank of gas was 38% worse than the feds’ rating of 6.8L/100 km for combined highway-city driving. One good thing, though, even in the real world – and with a smallish 65L tank – the Lexus can cruise for about 700 km between fill-ups.

And although some of its competitors are quicker, the RX 450h is no slouch with its new 4.5-litre Atkinson cycle V6 and electric hybrid motor.

The ride is very quiet and smooth. And, of course, the vehicle is totally silent when stopped because the gasoline engine shuts off until it’s needed again for acceleration.

It has a wonderful substantial feel, with a solid stance on the road whether cruising a high speed superhighway or navigating through tight corners. The electric power steering is light and precise and the suspension is up to handling the quick transitions when the road begins to resemble a slalom course. There’s standard vehicle dynamics control (VDC) with traction control and the continuously variable transmission (CVT) has a sequential shift mode.

There’s not a lot of wood in the cabin – just on the steering wheel, shift knob, cupholder cover and door armrests - but what’s there is real walnut or bird’s eye maple), highly polished and gorgeous. In fact, the RX 450’s interior is as comfortable as you’re likely to find – and not just for driver and front passenger. The sliding rear seats are also big and comfortable – unless you’re over six feet tall. Then headroom gets a little tight. There are back seat controls for audio and climate and large video screens in the front seat headrests.

The RX 450h lacks nothing in terms of luxury appointments. The $59,500 base model comes with leather, Bi-Xenon HID headlamps with automatic high beams, keyless ignition and entry, power locks/windows/mirrors/front seats, backup camera and Bluetooth capability. Our tester’s Ultra premium Package includes a 15-speaker Mark Levinson surround sound audio system, the dual screen rear seat DVD entertainment system, dynamic radar cruise control, intuitive parking assist, voice-activated navigation, Heads-Up display, pre-collision system and 19-inch aluminum alloy wheels.

Although the voice-activated navigation system could guide me home, it just didn’t want to show me where I lived on the map. This is the second vehicle I have tested recently where the nav system screen shows great expanses of nothing for the rural part of Canada in which I live.

The joystick that operates the navigation, audio and climate control systems is relatively easy to use, especially when compared to some of Lexus’ German competitors. There’s no tach on the instrument panel. In its place is a round gauge that shows whether the hybrid system is being charged, driven in its most economical range, or using full power.

This is a well styled crossover with sweeping chrome accents and brushed metal roof rails that help to make it appear longer and lower than it is. Whether it’s worth the extra money depends on just how green you want to be.
