Mercedes-AMG’s GT3 racecar employs 6.3-liters of free-breathing V8 muscle

Turbo? We don’t need no stinkin’ turbo.

Following a bit of teasing last week, Mercedes-Benz has unveiled the Mercedes-AMG GT3 racecar ahead of the 2015 Geneva Motor Show. Instead of using the 4.0-liter biturbo V8 from the AMG GT as predicted, the AMG GT3 does things the ‘old-fashioned way,’ equipping the 6.3-liter, naturally aspirated V8 from the SLS AMG GT3.

Performance specs for the track-only racecar haven’t been released yet, but the GT3 of 2011 produced 548 horsepower and weighed just 2,980 pounds. Like the old car, the new version was developed in accordance with FIA GT3 specifications, and is sure to be a stout competitor.

“We are entering a hard-fought and hotly contested competitive environment with the new Mercedes-AMG GT3,” said Tobias Moers, boss of Mercedes-AMG. “The high technological standard and fair race rules are spurring us on to push to take pole position with our new customer racing car. You can only give credible proof of your ambition to lead if you’re beating the very best in the game.”

In true AMG fashion, bold claims are backed up by bold capabilities.

Like the AMG GT from which the vehicle is based, the GT3 employs near perfect weight distribution, a low center of gravity, and a wide track width. It also equips double-wishbone suspension, which is made entirely of aluminum, as well as a 6-speed sequential gearbox.

The racing car has received the carbon fiber treatment throughout, as the engine cover, doors, front wing, front and rear aprons, sidewalls, side skirts, diffuser, boot lid, seat pan and the enormous rear wing are all made from the high-strength weave. The interior is carbon fiber-laden as well, and the driver will be protected by a roll cage made from high-strength steel.

Mercedes will open reservations for the AMG GT3 soon, with pricing being released closer to the on-sale date.

Your next ‘cheap’ new EV isn’t coming – unless you buy used

The global electric-car market is in a weird pricing flux. In Britain, Hyundai has opened orders for the Ioniq 3, a compact electric hatchback that starts at £22,245, or £18,495 after the country's £3,750 Electric Car Grant. The 61kWh version can travel up to 308 miles (WLTP range), while higher-end trims add features such as Matrix LED headlights and Hyundai's new Pleos Connect infotainment system, based on Android Automotive OS.

Cross the Atlantic, however, and that particular proposition disappears. Hyundai has no current plans to bring the Ioniq 3 to the U.S. Meanwhile, Cox Automotive put the average U.S. new-EV transaction price at $54,754 in August 2026. The gap is not simply about one car. It highlights a broader problem: while other markets are producing increasingly affordable electric cars, the U.S. still has remarkably few mainstream EVs around the 20,000-25,000 mark.

BMW iX4

BMW has officially revealed the iX4, and while the swooping coupe-SUV shape will probably get most of the attention, the numbers under the hood are what's really impressive. The BMW iX4 50 xDrive is rated for a preliminary maximum of 428 miles of EPA range, powered by a 112.2kWh usable battery and dual electric motors producing 463 horsepower.

The company claims it can sprint from 0-60 mph in 4.7 seconds. Just like the BMW iX5, the iX4 is a redesign of the brand's X4.
