The new, not-for-US Ford Ranger Raptor borrows its 10-speed automatic gearbox from its bigger brother, the F-150 Raptor. that Ford Performance actually considered using even more gears, as if 10 wasn't more than enough. Car Advice got the low-down on the Ranger Raptor's gearbox John Fallu, the transmission and driveline engineering manager for Ford Asia.
"We actually did simulations during the exhaustive testing process for the optimum number of gear ratios for a rear-wheel drive truck of this size and power," Fallu said. "We looked at seven speeds, nine speeds all the way up to 12 and 13 speeds, to see, from a performance perspective and an efficiency perspective, what truly is optimal for the design."
Ford isn't the only automaker to experiment with 10--speed gearboxes: Back in 2016, we reported about a Honda patent for an 11-speed triple-clutch gearbox. Right now, a number of automakers offer 10-speed gearboxes, though no passenger car exceeds that number of ratios.
