It#8217;s already a ago, but I vividly remember my #8216;encounter#8217; with the Lexus RX In 1998, our test route through northern Michigan and we the night in a national park. The morning, and for the first time in my I saw an eagle in full flight. It was a sight.

At that time was the first off-roader based on a car a type soon to become as a crossover.

Until now, you buy the RX350 with a 275 hp 3.5-liter V-6 or as RX with the Hybrid V-6. The model offers an upgraded of the Lexus Hybrid System of the V-6 and two electric motors, besides the with the normal petrol

Lowest CO2 in class

The exterior of the Lexus RX 450h is of a new design, but the sits on the platform of the Toyota That allows for the same set up as with the CVT with an electric and a second electric motor in the axle. The CPU, the management is lighter and more efficient and the 279 hp V-6 is more efficient too.

Lexus claims a reduction of be 23 in fuel consumption.

In the second 450h, the system#8217;s total output has been raised 27 hp to 299 hp and. more than the ML, Audi Q7 and abovementioned X5. But that is not the important achievement of the RD engineers. A of modifications in the power plant and the motors resulted in very low figures.

With only 148 CO2 per kilometre, the Lexus RX 450h has 23 per less emission and 10 per cent power than the outgoing In California the 2010 model the SULEV (Super Ultra Low Vehicle) status (Tier 3 in other states). With low CO2-emission the 450h by far beats the ML 450 Hybrid (185 g/km) and the Mercedes ML 320 CDI (245 g/km).

Hi-tech hybrid system

One of the that pays off for the new Lexus is the new V-6 engine running on the so-called cycle. This allows the valves to open longer and the valves to be closed for a longer thus making more use of the fuel. Lexus also cooled Exhaust Gas Recirculation the cooling of the exhaust gasses to from 880 to 150 degrees Centigrade.

Exhaust Heat Recovery the use of the remaining heat to allow the to reach its work temperature faster, allows the system to into electric mode faster.

New are the three driving Eco, EV and Snow. The Eco mode is to an indicator in the speedometer and provides a throttle action and air conditioning to support the driver to drive In EV mode the 450h automatically under electric motor This happens from the up to 25 mph.

You can also select mode yourself with the switch on the steering wheel. The switch allows you to choose mode. Then the pressure on the is automatically adjusted to reduce torque end wheel spin, the rear electric motor is to improve traction in case the wheels spin.

Not much was changed with to the batteries. As before, the new 450h nickel-metal hybrid, that of better cooling and a smaller could be positioned in a different

The engine is teamed to a six-speed CVT transmission, that works but allows for higher revs you would expect normally normal acceleration. There are new driving modes, Eco, EV and that improve the fuel of the hybrid system and the driving The EV mode is for driving on electric power exclusively, with no nor NOx emission.

The fuel consumption of the 450h is the of any crossover SUV around, with 6.3 km for the combined cycle.

In Europe, the RX has a suspension and power management for to Lexus) better acceleration not much influencing the fuel
