There are some odd-looking solar cars racing across Australia now

Being cooped up inside one of the cars racing in Australia’s biannual World Solar Challenge from Darwin to Adelaide looks like the most uncomfortable experience ever for those behind the wheel. You can imagine the drivers having to be lifted out of the vehicle by a small crane once they cross the finish line, their limbs having seized up somewhere south of Uluru.

Aimed at inspiring research and development work in sustainable road transport, the 30th anniversary of the 1,860-mile race kicked off on Sunday with 42 solar-panel-laden cars from 40 countries hitting the road across three classes of vehicle.

The Challenger category tends to get the most attention thanks to the cars’ often striking designs that allow them to reach speeds of just over 60 mph using only the power of the sun.

This year the race organizers decided to make things a little tougher for the designers and engineers who create the cars by decreasing the permitted size of the solar collector area on each vehicle.

The favorite to reach the finish line first is Nuna9 from the Dutch Nuon Solar Team, which is aiming for its eighth World Solar Challenge win. The team says it has tweaked Nuna9’s design for this year’s event by removing its overhanging nose to reduce aerodynamic drag.

“With our successes in previous years, every year is harder to get a great result,” the team said. “This means our students have to become more innovative every year.”

U.S. participation includes the Sundae solar car from Stanford University. The team said its design aims for “reliability and safety … rather than focusing primarily on speed, paying special attention to car handling when possible,” adding that the race is “a unique opportunity to exercise our car in the most intense way possible, truly proving its mettle and testing our team at the same time.”

Racers in the Challenger class will be out to beat the fastest time to date, set by a Japanese team from Tokai University, which crossed the line with a driving time of 29 hours and 49 minutes in 2009.

Besides the Challenger class, the Cruiser category focuses more on practical designs that you might actually want to ride in for more than a few minutes, and includes at least two seats. The Adventure class, meanwhile, comprises cars from previous races and could include those that don’t quite meet the requirements for the other two categories.

The vehicles, which make several stops along the route through Australia’s barren outback, are expected to cross the finish line in Adelaide on Thursday, October 12.

Rivian R2 vs R1S: How will Rivian’s cheaper SUV compare?
The front three-quarter view of a 2022 Rivian against a rocky backdrop.

Rivian has finally unveiled the R2, its long-awaited attempt at a more affordable electric SUV. The new vehicle may not be available just yet, but fans of Rivian's design aesthetics and feature set are already looking forward to being able to order the new car. The R2 is targeted at being a more affordable take on the electric SUV and will sit alongside the flagship-tier R1S.

Let's get this out of the way right now: The R1S is most likely going to be a better vehicle than the R2. Rivian isn't replacing the R1S with the R2 — it's releasing the R2 as a more affordable alternative, and there will be some compromises when buying the R2 over the R1S.

We’re finally getting to the fun part of automakers’ methodical quest to replicate their lineups with electric cars.

Performance versions of ordinary cars have been a staple of the auto industry for decades. But while we’ve already seen some variants of EVs boasting more power and more impressive stats — think Tesla Model S Plaid or Lucid Air Sapphire — the 2025 Hyundai Ioniq 5 N is the first to truly apply that format to an EV.
