Nico Rosberg reveals insane way they test electric hypercar batteries

While traditional gasoline or diesel-powered cars are simply crash-tested for safety, the electric motors in EVs are a lot more complex. While visiting Rimac to see his all-new hypercar, F1 ace Nico Rosberg discovered the dramatic way that manufacturers safety-check EV batteries.

If we said to you that testing EV batteries involved a lot of fire, many people wouldn’t believe us. Well, it’s true, as F1 star Nico Rosberg discovered while visiting the Rimac factory in Croatia, Europe.

Gasoline-powered cars are crash tested in a very conventional way. Cars are mocked-up, and put through a series of scenarios to test their structural integrity, including the safety of the gas tank.

With electric vehicles (EVs) having complex battery packs in place of gas tanks, the testing process is a lot more involving, and certainly just as dramatic to watch.

While visiting the Rimac factory to see the progress of his all-new 1900hp C_TWO electric hypercar, Nico was treated to a tour by owner Mate Rimac. They discovered a number of fascinating insights into how the C_TWO is being built and tested, but the safety checks for the batteries seem like something out of this world.

To ensure the batteries are safe (homologated) for use in EVs, they are literally set on fire. Since the lithium-ion inside the batteries is so flammable, they have the potential to burn for days on end. Therefore, they need to be tested substantially before they are approved for use.

The test process itself is wild. A fully-charged battery is placed above a vat of burning fuel, and passed through the flames a number of times on a mechanical rack. After 30-seconds in the flames, the battery is removed, and the flames must extinguish themselves within five seconds to pass the test.

As Mate Rimac says in the video, the extensive testing is partly due to people being “very cautious” of such new technology.

Thankfully, the batteries used inside the Rimac C_TWO passed the test with flying colors, but not every test goes so smoothly. With the recent legislation brought out in both the state of California and England to move forward the deadline of all new cars on sale being electric, we will likely see more and more EV hypercars in the years to come.

Petrolheads around the world will recognize the name Jeremy Clarkson. Once part of BBC’s Top Gear and now the host of the legendary Amazon Prime show The Grand Tour alongside May and Hammond, Jeremy Clarkson naturally owns quite a sizable car collection, along with a few surprises.

Jeremy Clarkson will go down in history as one of the biggest personalities that any car-based TV show will ever be linked to. Naturally, his years at the helm of various car shows, along with his history in journalism, has led him to owning an impressive collection of cars.

It’s not just cars in Jeremy’s garage, though. Having taken on his farm during 2019, he also owns a number of unusual machines, including a rather strange Lamborghini. Here are our highlights from Clarkson’s incredible collection.

Jeremy Clarkson’s supercars

Of course, Clarkson has a number of performance cars and supercars in his car collection. One of the most famous cars in his collection was the Ford GT, which he actually sent back to Ford after a well-documented issue with the alarm.

He also has a well-known love affair with AMG’s products. His first was an SL55 AMG roadster, though it wasn’t to be his last. Clarkson has also owned a number of other AMG-badged cars, including a CLK63 Black Series.

Given his history around supercars, Clarkson has owned more than most people would ever dream of having. These include, but are not limited to:

  • Ferrari 355 GTS
  • Mercedes-Benz AMG SL55 AMG Roadster
  • Mercedes-Benz AMG CLK63 Black Series
  • Aston Martin Virage
  • Lamborghini Gallardo Spyder
  • McLaren 675LT
  • Ford GT
  • Lotus Elise 111S

Classic Cars in Jeremy Clarkson’s collection

It’s not just the latest-and-greatest cars that are in Jeremy’s collection. There are also a number of classic cars in his fleet, including one of the most iconic BMWs ever made, as well as some vehicles from his time on Top Gear and The Grand Tour.

The most unusual car in Clarkson’s collection is undoubtedly ‘The Excellent.’ Created as part of a challenge on The Grand Tour, it is a lifted Mercedes SL convertible mated to a Land Rover chassis.

Alongside ‘The Excellent’ he also owns the gorgeous Alfa Romeo GTV6 that featured on the Scottish special episode during Season 2. He even knew that he’d own it after filming, saying during the show “generally when we finish these jobs these cars end up, I don’t know where. But I know where this will end up; At my house.”

The most iconic classic in Clarkson’s collection is the BMW 3.0 CSL.

Finally, the standout car from the collection is one of the most iconic BMW’s ever designed – the 3.0l CSL. Nicknamed ‘the Batmobile’ due to its massive rear wing, the CSL is the first true performance BMW, and is an appreciating classic.

While he doesn’t own all of them anymore, the full list of classics that Jeremy is known to own is impressive:

  • BMW 3.0l CSL
  • Alfa Romeo GTV6
  • Mercedes SL ‘The Excellent’
  • Ford Escort Cosworth RS
  • Mercedes-Benz 600 Grosser Limousine
  • VW Golf GTI
  • VW Scirocco

The weirdest car in Clarkson’s collection

While his crazy Grand Tour creations are certainly odd, most people wouldn’t expect Clarkson to own a certain Lamborghini. In this case, it’s a tractor for use on his farm – how very un-clarkson!
