Audi’s RSQ E-Tron Dakar Rally Car has won multiple stages in Saudi Arabia

Audi At this year’s Dakar Rally, we ran three ridiculously complex and cool hybrid electric vehicles. After a 13-day race, German carmakers have a lot of fuss.

In the stage victory, Carlos Sainz and Lucas Cruz of car No. 202 took the lead with two finishes in 1st and 2nd place and 3 times in 3rd place. Stephane Peterhansel and co-driver Edouard Boulanger finished second in the No. 200 car with one stage finish in first and third place. The Audi team concludes with Mattias Ekström and co-driver Emilberg Kvist, who rode Car 224 in the first, second and third finishes.

However, when the dust settled down, Ekström and Bergkvist were the most stable, finishing 9th overall, 41 hours 15 minutes 14 seconds behind overall winner Nasser Al-Attiyah, about 2 hours 42 minutes behind. And Matthew Baumel. Sainz and Cruz finished 12th overall in 42 hours 12 minutes 24 seconds. Peter Hansel and Boulanger finished 57th with a time of 106 hours 45 minutes 16 seconds. The duo got off to a devastating start to the rally when they took out the rear end of the RS Q E-Tron racer.

Audi hopes to revolutionize the rally with the RS QE-Tron, just as it did when it introduced the Quattro all-wheel drive system in 1981. However, the company knows that current battery technology cannot compete in long-term, multi-day rallies like Dakar. There is no range. That’s why a car’s 52kWh battery is charged on the go with a gas-powered 2.0-liter I4 turbo engine. Coupled to the engine is a motor generator unit that powers the battery. The other two motor generator units drive the front and rear wheels. In this way, the battery can supply enough power to the stage without stopping for recharging-some of them are as long as 500 miles.

I recommend that scoop I love it.

The car departs on a full charge every morning, but it can be difficult to keep the battery from draining quickly. Much of the Dakar Rally is spent navigating the dunes and doing a lot within range. Sand provides resistance as well as low tire pressure. According to Dakar rules, Audi’s motor generator units on the axle should be limited to a total of 288 kW, or 386 horsepower, and the energy converter can only supply 220 kW of power. Audi didn’t always expect to use more power than the car was producing, but there was a moment when the team saw the range drop sharply. However, a complex set of algorithms and engineering magic kept the battery in the specified state of charge.

Audi hasn’t announced torque for hybrid race cars, but the RS Q E-Tron can accelerate from 0 mph to 60 mph in less than 4.5 seconds on loose roads, limiting its top speed to 106 mph. I am. The battery adds an additional 816 pounds to the chassis. The car also has two electric motors, a battery, an energy converter, a gas-powered engine, and six cooling systems for the cabin. The vehicle also has a cable of about 2.5 miles and does not include an 800 volt cable for the battery. I don’t envy Audi technicians with this.

The RS Q E-Tron is a fairly sophisticated technology, but it still burns dinosaurs to produce electricity. Sure, we all want clean power, but getting there is a slow process.

I campaigned for two electric cars at a licensed motorsport event. The Rivian R1T Needed to be charged during the day Rebelle RallyBut I was rushing for navigation accuracy, not speed.In Mexico 1000, Volkswagen Charged ID 4 With a trailer in the road passage stage. In both cases, the power was supplied by a diesel generator, but Rebelle Rally’s charging unit could run on hydrogen power, and only logistics issues prevented it.

My point here is that Audi is using the technology currently available. It’s not ideal, but it’s just one step on the road to long-range batteries.

At the Dakar Rally, the team faces many new challenges, not just driving experimental vehicles. The loadbook was distributed 15 minutes before the start of the stage that day. Over the past few years, co-drivers have received books the night before, enabling reviews and notes.

In addition, this year’s roadbook was digital. There were two screens in front of the co-driver. The left shows a very rough view of the terrain and its roads. For example, a notebook might have a rock represented by an irregular circle on one side and a building represented by a rectangle on the other side. In reality, the rock can be of any size and the building can be a hut. If this screen failed, the co-driver had a sealed paper loadbook as a backup. On the screen on the right, the navigator can see the direction and validation when the virtual waypoint is reached.

This is the first time Audi has entered the Dakar Rally, but it’s not a stranger to an electrified race. The company used electric drivetrains on the R18 E-Tron Quattro to win the season in Formula E in 2017 and 2018 and the 24 Hours of Le Mans in 2012. In fact, the motor generator unit of the Dakar vehicle has been pulled up from its current state. Audi E-Tron FE07 Formula E-Car-Slight changes have been made.
