Huh?
Ford Mustang Mach-E Owners Are Puzzled by Low Trap Speeds at the Drag Strip (thedrive.com)
Excerpt:
The latest consternation comes from a timeslip from a base Mustang Mach-E GT. Running at a 72% state of charge and rated at 480 horsepower, the vehicle laid down a 12.685 quarter-mile time while trapping only 100 mph. The owner also noted a significant reduction in perceived acceleration beyond the 80mph mark. Notably, the times are only a hair slower than those achieved by the owner of GT Performance Edition, which we covered in August—the uprated model achieving a 12.657 second quarter-mile while again only trapping 100mph.
The thing that has the community all riled up is that the trap speeds recorded are a good 5-10 mph slower than would be expected for a mid-12s quarter-mile. Further complicating the issue, tests by Car and Driver had the lower-tier Mustang Mach-E Premium AWD model, with just 346 hp, deliver a 13.8 second quarter-mile at a faster trap speed of 101 mph. It's left owners scratching their heads as to the real issue at play.
Thus, for a single-speed electric vehicle using permanent-magnet motors with field weakening, a drop-off in acceleration is expected as the power available flattens out while aerodynamic drag increases. The issue with the Mustang Mach-E GT models, however, seems to be that this drop-off is happening sooner than owners would otherwise appreciate. Comparisons, whether fair or not, have regularly been made with the Tesla Model Y Performance. With slightly less power but also less weight, the Tesla rival has delivered 11.91 second quarter miles with a trap speed of 116 mph as reported by AutoEvolution.
This has left some owners of the Mach-E frustrated, questioning why their more powerful vehicle isn't closer to the Tesla in a quarter-mile despite similar 0-60 times in the 3-second range. However, a look at their relative top speeds may shed some light on the matter: the Mach-E GT tops out at 130 mph, while the Model Y Performance quotes 155 mph in comparison.
It suggests Ford may have tuned the Mach-E GT models for great off-the-line starts and 0-60 times, while making a trade-off in top-end performance. It also bears noting that times posted on forums have often been recorded by owners in the Unbridled Extend drive mode, which aims to maintain consistent performance lap-to-lap on a track rather than giving everything for one big pass down the drag strip.
