Škoda Enyaq received all-wheel drive. The difference in consumption drove us crazy


 

The first large Škoda electric car has so far only been sold with rear-wheel drive. The current ATV improves dynamic properties without compromising space utilization, you didn't lose the trunk under the front hood, as there was none. However, the added electric motor slightly increases the weight and inertia, so we used the first presentation for a short measurement of consumption.


Briefly recall that Enyaq uses the basics of electric Volkswagen ID.3 and ID.4, which means a battery almost across the floor and the main engine at the rear. The battery frame raises the floor, which is why the SUV body is much more beneficial here than with a conventional drive, the rear seats can be anchored higher, and the trunk can be deeper.


The rear-wheel-drive was chosen by technicians due to the transfer of power to the road. As the car accelerates, it bows and relieves the bow. Which didn't matter as long as it was loaded with a two-meter diesel with a multi-speed transmission. Even today's light petrol three-cylinder engines have a problem starting up a snowy hill. Not to mention an electric car, whose 450 kg battery rests between the axles.


The rear wheels, therefore, transmit power more safely. However, the electric motor, which starts with all the force from zero speed, makes the tires really busy. That's why on the Enyaqu iV 80 you can now pay extra for the letter "x" in the name and a smaller electric motor on the front axle to distribute the work more evenly.


Such an ATV design should be more energy-efficient than a conventional center differential and all-car drive shaft arrangement. It is no coincidence that the electric motor on the second axle is also used by hybrid Toyota, whose primary energy source is petrol.


But that doesn't mean it would work perfectly. The electric motor also has some losses, so we were interested in how much energy those interested in better traction must sacrifice. We used the first presentation of the Enyaqu iV 80x, which took place last week at Mcely Castle near Nymburk, and brought a basic version of the iV 80 with the same battery and rear wheel drive.


Apart from the logo with the letter x, you will not recognize the ATV from the outside. In our case, it is distinguished by an ice blue-silver color and Sportline equipment with a more aggressive mask and bumper. The 4 × 4 drive itself has no selectable modes. It intervenes automatically and the logic changes only as you switch the whole car from comfort to sports mode.


From Mcel we set off on a 100-kilometer circuit combining roads of all classes and the motorway - via Jičín and Turnov to Mladá Boleslav and back. The route first winds through the narrow and winding districts of St. George's Forest, where we gain respect from Enyaq. With a low center of gravity, it is agile, but the width of a middle-class car and more than two tons of weight do not encourage playfulness. We prefer a fluent style.


Enyaq feels best on the wide first-class paths intersecting the romance of the Bohemian Paradise. With a hundred marmots, it is completely noiseless, it is placed in long arches with a view, and the landscape passing by seems to be just projected on the glass.


If only we didn't have to stop so often at repaired sections and narrowings controlled by traffic lights. Ten kilometers behind Jičín, we have been comparing consumption for a long time. Zadokolka wins with a ratio of 18.1 vs 19.0 kWh / 100 km. So the difference is five percent, a little over three to four percent, as stated by the manufacturer.


After Turnov we drive on the motorway and with 130 km / h on cruise control, we cut the air towards the southwest. The ride is still comfortably quiet, but the heavyweight is felt every time the truck in the left lane slows us down and we have to pick up speed again. Enyaq is not Tesla and will not run away from the diesel Octavia.


The last kilometers lead us back to Mcel on the road in a slightly worse condition, so we appreciate the suspension tuned to the ideal center. Comfortable and pliable, but at the same time strong. Enyaq doesn't sway or jump.


Behind the castle gate, we are comparing consumption again and it is not enough to be surprised. Rear-wheel drive 17.8 kWh, ATV 18.1. The difference dropped to two percent, even though on the highway all the engines had to get out of the optimal efficiency range - at least that's our layman's idea.


However, Škoda technicians brought us interesting information from it. The front axle, unlike the rear, is rotated by an asynchronous motor, which has two advantages. First, it puts less resistance when idling, that is, when the ATV does not intervene.


But second, it is more efficient in some regimes. Specifically at high speed and low power, which is typically steady speed driving on the highway. The computer, therefore, sends a larger share of energy forward, thus reducing consumption and at the same time stabilizing the car in direction.


If we add that our ATV had one-inch larger wheels and two centimeters wider tires on them, the difference is basically negligible. It will depend more on how many of your roads will lead along the highway. For example, on the way to the alpine slopes, the Enyaq iV 80x combines both advantages: it helps traction in the snow, but it hardly increases consumption. The Kodiaq 4 × 4 diesel would burn 15 percent more diesel than the front wheel.


Another thing is if it pays off. The cheapest Enyaq with a smaller battery at 62 kWh costs CZK 1,072,900. The more powerful 77 kWh battery is 130,000 CZK more expensive, the ATV another 75,000 CZK. Sportline equipment with an additional heat pump and LED Matrix headlights cost CZK 1,408,900. A similarly equipped Kodiaq 2.0 TDI 110 kW 4 × 4 Style Plus costs CZK 1,069,900.


The return will depend, among other things, on the price of electricity, which is largely unknown in the long run. With a real consumption of 18 to 21 kWh / 100 km, Enyaq with a usable capacity of 77 kWh will travel 360 to 430 km on a single charge. On the way to the Alps, it will come in handy to charge up to 130 kW, which is standard in the ATV. For other versions, the base is 50 kW, for faster charging, CZK 13,500 is added
