Volkswagen ID.R Pikes Peak: Why Everyone Was Wrong About Electric Race Cars

Volkswagen ID.R Pikes Peak: Why Everyone Was Wrong About Electric Race Cars

The mountain doesn't care about your marketing budget. When you stand at the starting line of the Pikes Peak International Hill Climb, you’re at 9,390 feet. By the time you gasping for air at the summit, you’ve climbed to 14,115 feet. It’s brutal. For a century, this was the playground of screaming turbochargers and internal combustion monsters. Then, in 2018, a silent blue-and-silver wedge showed up and basically broke the sport.

Most people thought the Volkswagen ID.R Pikes Peak was just a PR stunt. A flashy way for VW to move past some "difficult" headlines by showing off a battery-powered prototype. They were wrong. This wasn't just a fast EV. It was a 680-horsepower statement that made the previous all-time record—held by the legendary Sébastien Loeb in a fire-breathing Peugeot—look like a Sunday drive in a school bus.

The Day the Mountain Went Quiet

June 24, 2018. Romain Dumas, a guy who has won Le Mans twice and knows a thing or two about driving on the edge, strapped into the cockpit. The goal wasn't even the overall record. Honestly, VW was publicly targeting the electric record of 8:57.118. That seemed safe.

Then Dumas started driving.

He didn't just beat the electric record. He didn't just beat the overall record. He became the first human being to ever crest that mountain in under eight minutes. 7:57.148. Read that again. He took 16 seconds off Loeb's "unbeatable" time. It wasn't even close.

Why the Volkswagen ID.R Pikes Peak Was a Different Beast

You’ve gotta understand why gas cars struggle here. As you climb, the air gets thin. Engines need oxygen to burn fuel. By the top, a normal engine loses about 30% of its power. It’s like trying to run a marathon while breathing through a cocktail straw.

The Volkswagen ID.R Pikes Peak didn't care.

Electric motors don't need to breathe. Whether you're at sea level or on the moon, you get 100% of that torque the moment you touch the pedal. But power is only half the story. The car weighed less than 2,500 pounds including the driver. That’s absurdly light for an EV carrying a massive battery pack.

The Aerodynamics of a "Park Bench"

If you look at the ID.R, the first thing you notice is the rear wing. It’s massive. François-Xavier Demaison, the technical director for the project, famously compared its size to a park bench.

Because the air is 35% thinner at the summit, you lose 35% of your downforce. To fix this, VW's engineers went overkill. The wing and body were designed to generate more downforce than the actual weight of the car. In theory, if you drove it fast enough upside down on the ceiling, it would stay there.

  • Acceleration: 0-60 mph in 2.25 seconds. Faster than a Formula 1 car.
  • Power: Two electric motors producing a combined 500 kW (680 PS).
  • G-Forces: Dumas was pulling over 3.5g in some corners.

The Battery Secret

They didn't use a massive "long-range" battery. That would be too heavy. Instead, they built a 43-kWh lithium-ion system specifically for a 12.4-mile sprint. It was all about power density, not endurance.

Interestingly, they charged the car using generators running on glycerol. Basically, a sugar alcohol by-product of biodiesel. It burns almost entirely clean. They had a rule: if the race was red-flagged, they had to be able to fully charge the car in under 20 minutes. It was a logistical nightmare that they handled with clinical German precision.

It Wasn't Just About the Specs

Specs are great, but Pikes Peak has 156 corners. If you miss one, you aren't hitting a tire wall—you're falling off a cliff. Dumas later said the ID.R was the most impressive car he had ever driven, but he also admitted the pressure was immense. You only get one shot. If a cloud rolls in (which it did during his run), or the temperature drops, your months of work go up in smoke.

Dumas mentioned that even with the fog and some damp patches, the car felt glued to the asphalt. That’s the magic of torque vectoring. Since there’s a motor on each axle, the car can computer-manage exactly how much power goes to the front versus the back in real-time. It’s essentially "cheating" the laws of physics.

What This Changed for You

You might think a multi-million dollar prototype has nothing to do with the electric SUV in your driveway. But the ID.R was the laboratory. The thermal management systems—how they kept those batteries cool while dumping massive amounts of energy—directly influenced the ID.4 and ID. Buzz.

The record proved that EVs weren't just "golf carts" or "commuter cars." They were the new performance ceiling. After Pikes Peak, the ID.R went to the Nürburgring and smashed the electric record there too (6:05.336). It was a world tour of dominance.

Actionable Insights for the Tech-Curious

If you’re looking at the future of performance, here’s what the Volkswagen ID.R Pikes Peak taught us that still applies today:

  1. Weight is the Enemy: Even with 680 horsepower, the car only worked because it was light. If you're looking at performance EVs, check the curb weight. Heavy batteries kill cornering.
  2. Altitude is the Great Equalizer: If you live in a high-altitude area (like Denver or Mexico City), an EV will objectively outperform an equivalent gas car because it doesn't suffer from oxygen starvation.
  3. Thermal Strategy over Capacity: A smaller battery that can discharge and charge quickly is often better for performance than a huge battery that gets heat-soaked and throttles your power.

The ID.R project was eventually mothballed as VW shifted focus away from factory-backed internal combustion and prototype racing, but the 7:57.148 mark still stands as a ghost on the mountain. It’s a reminder that sometimes, the quietest car in the room is the one you should be most afraid of.
