Feature Showdown
Both come with modern infotainment systems. Apple CarPlay and Android Auto are standard across both.
The Mercedes-Benz GLA stands out with wireless Apple CarPlay/Android Auto — features our data doesn't list for the Mercedes-Benz GLB. The Mercedes-Benz GLB counters with Apple CarPlay, head-up display, wireless charging, panoramic roof, heated front seats and power tailgate. Which feature set matters more depends on your daily routine and priorities.
Interior trim differs: the Mercedes-Benz GLA gets synthetic leather upholstery while the Mercedes-Benz GLB offers black artico man-made leather.
Equipment few rivals have, on either carShowHide
Drivetrain
The Mercedes-Benz GLA uses a Petrol producing 120kW and 270Nm of torque, sent through a automatic to a FWD layout. It covers the 0-100km/h sprint in 9.1 seconds.
The Mercedes-Benz GLB lines up making 120kW, paired to a 8g-edct dual clutch transmission, 8-speed automatic driving the front wheels. It gets to 100km/h in 8.7 seconds.
Power output is identical on paper, so the difference comes down to tuning, weight distribution, and suspension. In the 0-100 sprint (manufacturer-claimed), the Mercedes-Benz GLB is 0.4s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Space & Comfort

Warranty: 5 years / Unlimited (Mercedes-Benz GLA) and 5 years / Unlimited (Mercedes-Benz GLB).
Where each one leads
The Mercedes-Benz GLA: lower fuel or energy costs on our assumptions ($1,767 a year against $2,138).
The Mercedes-Benz GLB: nothing in the figures we hold puts it ahead of the Mercedes-Benz GLA.

How to read this page. Prices, specifications, ANCAP ratings, warranty, the CarSorted Score and the verdict come from our records for the grades shown, sourced from the manufacturers' Australian documents, and change when those records change; the date each was last checked is printed under the headline. Prices are recommended retail prices before on-road costs unless marked drive-away. A plug-in hybrid's fuel figure is labelled with its basis: with a full battery (the certified combined figure) or as a hybrid (battery depleted). Charging and running costs are estimates on the stated assumptions. Always confirm price and specification with the manufacturer or dealer before you buy. CarSorted does not accept payment for recommendations.
