Ford Mustang Mach-E 1400 First Drive: An Insane, 1,400-hp Electric Frankenhorse
Drift-ace Vaughn Gittin Jr.'s RTR and Ford Performance created an EV track shredder.Vaughn Gittin Jr. is a great passenger. You might know him better as a superlative driver and a peer to hard-charging, energy-drink-hawking drift kings such as Tanner Foust, Ken Block, and Travis Pastrana. But should you ever find Gittin in your passenger seat, know that he's cool as a cucumber. I learned this when I spun his electric, seven-motor, 1,400-hp mutant version of the Ford Mustang Mach-E on the infield track at Charlotte Motor Speedway.
The turn was a tight left up a crest, and although Gittin had already warned me there was a real possibility of lift-off oversteer, I still spun the crazy "SUV" off the track and onto the lawn. "Don't worry about it," he said, easing my embarrassment. "I did the same thing earlier." That's probably how he knew his monster might do that.
What Is It?
We've of course covered the Ford Mustang Mach-E 1400 prototype before; please click that link if you want all the nitty gritty details. The 10,000-foot view is that Gittin's Ford tuning house, RTR Vehicles, collaborated with Ford Performance to build an over-the-top, all-purpose hooning machine. Instead of two east/west motors as found in a normal Mustang Mach-E, the Mach-E 1400 hasseven: three in front, four in back. Unlike most electric vehicles, the Mustang Mach-E 1400's motors reside on a driveshaft and face north/south. Why? Turns out if you want to go drifting, you need to run all the power and torque through a differential. Additionally, with a diff, the gear ratios can be swapped out easily. This makes the car more than just a one-trick drift pony. For instance, the track configuration I drove had the rear diff set up with 130-mph gears, while the front diff was at 150 mph. More on that later. For drifting, Gittin runs only the rear motors through an 85-mph set of gears. Also, the Mustang Mach-E 1400 uses an 800-volt electric architecture.
A Weighty Challenge
What's one of the two big problems with performance EVs? Batteries are heavy, for one. The other combined issue is that batteries run out of juice relatively quickly when driving flat out, and they take too long to recharge. Nobody has cracked the latter challenge yet, but RTR and Ford Performance came up with something novel to address the first one.
The Mustang Mach-E 1400's battery chemistry was chosen because it discharges as quickly as possible. When electricity discharges from a battery, it generates a relatively small amount of heat. However, when you flow electricity back into a bunch of cells, a lot of heat is created and the battery typically needs to be cooled, especially when we're talking high (800V) voltage.
How do you cool a lithium-ion battery pack? With Gatorade! Fine, with electrolytes—salty, mineral-enriched water. But if you only need to cool the battery while the car is charging, why bother carrying the water and its weight on board? Instead, RTR and Ford Performance plug in a liquid-cooling pump while the Mache-E 1400 charges. That way, the cooling liquid is never in the vehicle while it's driving. That said, even with a relatively small (and liquid-free) 57-kWh battery, the Mustang Mach-E 1400 still weighs about 5,000 pounds.
