LEXUS has just raised the game in the fierce fight for buyers looking at zero-emission pure battery cars.

Enter the Lexus RZ 450e series of nine models from £55,595 to £66,695 in Urban, Premium, Premium Plus and Takumi with choice of 18 or 20-inch wheels and single or bi-tone paint finishes.

The 450e has the latest electronic axles effectively providing four-wheel-drive while the newer two-wheel-drive RZ 300e series costs between £49,995 and £61,095, but shares the same trim specifications.

The RZ 450e has a 150KW front e-axle motor and 80kW motor on the rear e-axle which on-board computer controls to ensure the optimum grip in any conditions and responses to the driver's input on throttle, brakes and steering.

To maximise the powertrain there are four selectable drive modes, normal, eco, sport and Range, the last ensures battery power and systems are optimised to stretch out the charge as far as possible. The other modes are biased to bring out what a driver prefers at a particular time with the rear motor first engaged and adding the front motor if required.

Paddles on the column give four levels of deceleration from mild in eco to mighty in sport and a driver can fine tune these as well to taste.

For all its state of art powertrain permutations, the RZ 450e suspension is fairly conventional with front MacPherson struts and rear double wishbones with trailing arms fitted with self-sensing shock absorbers to vary responses on particular surfaces.

The steering gave a lot of feedback and the turning circle was good in town without being twitchy on open roads, the brakes really were up to anything thrown at them and held the heavy car on a steep slope.

The low centre of gravity pulled down by the under-floor battery pack meant it cornered flat and fast with hardly any body roll or pitching under braking or acceleration.

Generally it was extremely comfortable but occasionally a really bad piece of road would be felt inside and the usually composed cabin would be roused by a rumble from the wheels and suspension.

Access was excellent for occupants and when using the boot with the power cables neatly housed in their own compartment beneath, which meant you might have to move luggage or bags if you wanted to charge at some points.

Visibility was excellent despite a high waistline with sensors front, back and to the sides ensuring a driver was always aware of surroundings and threats.

Intelligent lane control, speed warning and integrated cruise control made a long trip very easy even in busy traffic.

Very good self-dipping headlights were bright without dazzling oncoming vehicles, wash and wipers were highly effective.

The driver has a really wide sweeping instruments display with essential gauges infront and the infotainment and comfort controls alongside over the centre of the car's fascia. Everything was very simple, clear and quickly adjusted.

Two big sunroofs added a spacious feel to the cabin and the air conditioning kept everything in check with fine settings for heads, bodies and feet throughout the interior.

Seat adjustment was excellent for those infront with plenty of wrap-around support and just a little less padding on the back split seats. Room was good throughout.

With so much technology to touch and try it was interesting to vary the deceleration and try different drive mode and this meant the test car's range went from an indicated 250 miles at the start of our drive to finish up after two charges with an indicated 210 miles over a mixture of motorway, main and secondary roads in light to moderate traffic and we think this is probably a fair indication of what you could expect. It comes with a rapid charging ability should you need it as well on a longer journey.
