Review Porsche Cayenne Turbo S E-HybridAugust 28, 2019
Silver crossover silently accelerates when leaving the autobahn. The speed is rapidly increasing, but in the cabin it is still quiet – the gasoline engine is silent, and sound insulation and double side windows reliably protect against road noises. And only at the maximum for an electric motor of 135 km / h the V-shaped “eight” comes to life with a noble bass somewhere in the bowels of the engine compartment.
The fact that the history of Porsche hybrid cars began precisely with the Cayenne, which can be given a stretch of family status, is not at all surprising. A crossover with this type of drive was shown back in 2007, but mass production began in 2010 with the advent of a second-generation car. Four years later, the version of the E-Hybrid was able to recharge from the network. But never before has the hybrid Cayenne been the fastest in the gamut.
Moreover, today the Cayenne Turbo S E-Hybrid is the most powerful crossover not only of the brand, but of the entire VAG concern. Even the Lamborghini Urus lags behind the hybrid Cayenne by 30 liters. With., however, it beats him two tenths of a second when accelerating to 100 km per hour. But could one imagine a few years ago that hybrid technologies would progress at such a speed?
The total of 680 liters. with. hybrid Cayenne develops the efforts of a 4.0-liter V8, familiar to us from the Turbo version, and an electric motor. The latter is integrated into the automatic transmission housing and synchronized with the gasoline engine through an electronically controlled clutch. Depending on the selected mode and battery status, the system itself determines which engine to give priority to at the moment, or completely disables the internal combustion engine.
But at speeds of 200 km / h you do not have to choose – in such conditions, the electric motor just needs the help of a gasoline engine. And if you push the accelerator pedal even harder, Cayenne will rush forward with lightning speed. The power reserve is so huge that the crossover absolutely does not care what speed to accelerate. In such modes, you have to especially carefully follow the navigation tips on the projection display, because three hundred meters to the desired turn fly almost imperceptibly.
By default, the Cayenne hybrid operates in E-Power mode and is driven only by an 136 horsepower electric motor. It seems to be a little, but for a measured ride in the city hardly more is required. An electric motor draws about 19 kWh from the battery for every 100 km, and the declared electric mileage is 40 kilometers. In Germany, hybrids with such a power reserve are equated with electric cars, which gives them the right to move in the public transport lane and use free parking. And in some EU countries, owners of such cars are also exempt from tax.
But this is theory, and in practice, Hybrid Auto mode will be the most popular. It connects to the electric motor a V-shaped gasoline “eight” with double turbocharging, and the control electronics determines when and which engine to give priority, based on the maximum possible fuel economy. In hybrid mode, there are two additional settings, E-Hold and E-Charge, which can be activated inside a special menu on the central screen.
The first allows you to save the existing battery charge, so that you can use it where necessary. For example, in a special ecological zone where the movement of cars with internal combustion engines is prohibited. And in the E-Charge mode, as you might guess from its name, the battery receives the maximum possible charge, without wasting it on the movement of the car.
Two more modes are familiar with other Porsche models. When switching to Sport and Sport Plus, both motors are constantly running. But if in Sport mode the electronics still makes sure that the battery charge does not fall below a certain level, then in Sport Plus the car gives everything it can, without a trace. When starting from two pedals, the Cayenne Turbo S E-Hybrid accelerates from 0 to 100 km / h in just 3.8 seconds, but the linearity of acceleration is particularly impressive. The maximum 900 N · m of thrust is available in a wide range of 1500–5000 rpm, and all transient modes are smoothed by an electric motor.
Together with two motors and a gearbox, the chassis also goes into combat mode. Air balloons lower the crossover to a minimum of 165 mm, active shock absorbers are readjusted to the most accurate reactions, and the roll suppression system eliminates the slightest deviations of the body from the horizontal. With these settings, even a 300 kg heavy Cayenne can be easily tucked into turns.
It’s nice that already in the basic version Turbo S E-Hybrid is equipped with carbon-ceramic brakes. True, the pedal will have to get used to the specific feedback. This is due to the hybrid component. When you press the brake, the car slows down with the help of regenerative braking, and only then does the hydraulics work. At first it seems that the hybrid Cayenne is either slowing down or slowing down too much. But in a day, you still find a common language with the brake system algorithm.
The lithium-ion battery that powers the electric motor on the Porsche Cayenne hybrid is hidden in the underground of the trunk, so I had to say goodbye to the dock, and the total volume of the luggage compartment decreased by 125 liters. If you use an inverter with 7.2 kW included in the basic equipment and a 380-volt three-phase socket, then it takes only 2.4 hours to fully charge the battery from a 16-amp three-phase network. Charging from a regular 10-amp network with a voltage of 220 V will take six hours already.
All the same applies to the hybrid Cayenne Coupe, which itself was introduced relatively recently. There is nothing to tell about the differences in the behavior of cars with two types of bodies – the Coupe has the same power unit, almost the same mass and exactly the same numbers in the technical specifications table. The only difference is that the hybrid Cayenne Coupe can conquer German autobahns not only silently, but also quite beautifully.
