Mercedes-Benz's most-affordable SUV option is getting an update. The GLA will get a minor makeover for 2019, in line with the rest of the refreshed range. Expect the A-Class's 1.3- and 2.0-liter engines to carry over – with an A45 option rumored to produce up to 400 horsepower. Expect to see the new GLA before the end of the year.
