The 2021 Chevy Trax subcompact crossover integrates a capless fuel fill system, a new feature for the subcompact crossover vehicle.
Capless fuel fill makes refuelling at the pumps a little bit easier by doing away with the traditional screw-on cap in favor of a small spring-loaded flap in the filler neck. The flap automatically pushes inward when the user goes to insert the fuel nozzle, saving them the trouble of unscrewing a fuel filler cap.
The spring-loaded mechanism also prevents fumes from evaporating from the fuel tank once the user is done filling up. In fact, capless fuel fill can actually reduce fumes lost over a traditional cap, as it immediately seals the passageway to the fuel tank once the nozzle is removed. A traditional cap, by comparison, takes longer to screw back on – especially if it is not on a tether and must be fully removed before filling up.
The majority of GM vehicles now feature capless fuel fill like the Chevy Trax now does, with virtually all of the automaker’s new or redesigned vehicles featuring this system. We imagine it will become more commonplace throughout the industry in the coming years, as capless fuel fill is simpler from a manufacturing standpoint and makes life a little bit easier for vehicle owners. Anyone who has left their gas cap behind on a fuel pump or driven away with it on their roof will be happy to see this feature implemented industry-wide.
GM has only applied minor changes to the 2021 Chevy Trax, including deletion of the Premier trim level, new exterior colors, new interior options, an equipment reshuffle, and new packages. Trim levels include the LS FWD, LS AWD, LT FWD, and LT AWD. Additionally, just one engine choice is offered, the turbocharged 1.4L LUV four-cylinder gas engine up until November 2020, which was replaced by the turbocharged 1.4L LE2 engine. Both are paired with a GM six-speed automatic.
