Test NX 300h Lexus F Sport: driving dynamics and consumption (part II)

While promising a very low fuel consumption is not a champion of savings. When compared to a competitor gasoline, there will be big difference in town, but a diesel road you can do "best". In driveability, it's another story.

We continue to analyze the Lexus NX 300h, that despite being the sporty version of the range, it has exactly the same mechanical configuration that their brothers range. It is a 2.5 petrol engine, Atkinson cycle with 155 hp, assisted by two electric motors. The rear engine provides all-wheel drive.

All NX 300h have combined 197 hp, 4x2 or 4x4 are

Lexus diesel engines quit and has none in its catalog. This version is called to compete with the Diesel SUV competition, as Audi Q5 2.0 TDI or BMW X3 xDrive20d. However, consumption is not necessarily lower, although we talk about a approval of 5.3 l / 100 km gasoline, in this case.

During our test, we were in reserve after 610 km, approximately 7.8 l / 100 km on average. Practicing a smooth ride, not to exceed legal speed computer average was around 6 to 6.2 l / 100 km. Measurement error is remarkable computer, about one liter less. Our result almost coincides with American approval of this model.

NX 300h have an electric motor gasoline by the front axle and having a rear wheel drive electric motor. No shaft connecting the axes

The greatest potential for saving Lexus Hybrid Drive technology is in urban areas, as electric traction lasts longer and operation of the gasoline engine almost halved. But if we demand road performance, the advantage is not so obvious. We will not go short notice that power, only make a little more noise.

Circular electric mode is a joy, no Diesel can compete with that

In the test has combined all kinds of driving, aggressive mountain passes to the highway and relaxed on conventional roads. Minimum consumption I've been able to get has been 4.5 l / 100 km according computer, nearly approval values ​​if you count the measurement error. Yes, I clarify that went downhill and not to exceed 110 km / h.

Up to 80 km / h, you can circulate 100% electric mode, and if we demand little power. If the gasoline engine is off and does not turn, we will see a green light on the dash that says "EV". Electric range in level is not greater than 2 kilometers usually is a heavy car. Instead, with a longer decline, you can make a few more, if the driver dominates the route and anticipates everything.

We can see the cams to change, sport pedals, shifter and on your left, the selector wheel driving modes

The selector wheel It lets you choose four driving modes, Most drivers prefer the way normal. The quietest will choose "ECHO", with a less sensitive accelerator, artificial sound (ASC) offline and lower consumption of air conditioning. Low consumption if the driver behaves in the same way, if not, no.

When we want more action, we choose "SPORT", a board with conventional instruments (counter instead of potentiometer) and dyed red. The artificial sound becomes a little more present, and the throttle becomes more sensitive. Mode "SPORT +", Additional selective damping (AVS) exclusive of F Sport it becomes more dynamic, although I have not noticed a big difference.

It is difficult to fill the battery, even down a port

In addition, we have the "EV mode", It is allowing greater use of electric propulsion, at the expense of wasting the batteries before. It is a little electric acceleration allowed as long as the battery charge allows and urban speeds. This mode must be used carefully, it can be counterproductive if too low, charging is to recover gasoline, there is no outlet.

Dashboard mode "ECHO" and normal. Modes "SPORT" the left knob becomes a tachometer dyed red.

Like all hybrids of the brand, when we lift off the throttle recover energy for battery. If steps on the brake smoothly, we will increase the energy recovered, and the car decelerates before, with the potentiometer we learn to be metered braking to make it more effective. If you continue pressing the pedal, and come into operation disc brakes: for that last longer than a diesel competitor.

Normally the gasoline engine does not feel, and when it starts and stops is imperceptible to the average driver. Yes you will notice its presence when we demand powerful acceleration, or when ascending a slope prolonged. The sound is not unpleasant, but in contrast to the silent operation that boasts.

The artificial sound does not accompany the actual engine, and come to overlap

While we are talking about almost 200 hp, the perception of acceleration is not going to be very intense about how the gearbox is a epicyclic planetary gear. Although there are paddles for changing gear, it is really only one way to control the retention that makes the gasoline engine will not accelerate even if "we reduce". For better or worse, it is not a conventional gearbox. What it does is recovering fast speed and released.

Disc brakes may seem very small, but they are effective. Most of the time the car will brake with electric motors, greatly reducing the use of discs and pads

With a weight in order of march more than 1.8 tons, It is a heavy car. Accelerates to 100 km / h in 9.3 seconds, as a saloon 150 hp, and the maximum speed is limited to 180 km / h for technical reasons. Interestingly, the speed limiter can be set at 260 km / h, does anyone understand it?

Cornering, if we want to go fast, we have to tread lightly because stability control is very intrusive and can abruptly braking a wheel so that we cut the fun. You can not switch up, just from standstill and up to 50 km / h. The body does not swing excessively, the suspension is durita, but this is not a sporting it looks at it.

With all-wheel drive, it has good traction even on a track with a little mud, but on the road with good weather makes it hard to justify. One of the advantages of the hybrid system is that it can move as slowly as you like, both in electric mode as the gasoline engine on, by the particularities of transmission.

See something in the mirror, at least, imposes. It is what designers wanted to transmit aggressiveness. LED headlamps turn night into day, thanks much

The "Grace" cars like the NX 300h is that they are high and give a psychological sense of security. Then road is more gastón, clumsy and heavy as a saloon, brakes worse and has worse performance. I have really enjoyed their huge mirrors allow a mastery of what is behind the car, even vehicles in the blind spot, as the F Sport You do not have sensors to be reminded of that.

As roader, I insist ... not suitable

Or move through a smooth track with no bumps or rocks, or rather not off the road: it's like a sedan, but with more headroom. If snow tires are summer road and, like any sedan. Anyway these prints are also transferable to most of its competitors, not that I want cebarme with Lexus.

The NX 300h F Sport It is essentially a car image, It is sportier than a normal NX 300h far the suspension is harder and emulates (or attempts to emulate) the sound of a V8. In addition, it has available all the top-end equipment, which does not have aesthetics F Sport, but a more discreet.

If we look at the underside of the NX 300h we found that is not intended to exit road. Its wide wheel arches and black plastic protections are simply props, it's what the customer wants this segment as absurd as it seems

In the next installment, we end ...
