The smallest SUV in the Mercedes-Benz lineup has a sporty soul, as evidenced by its aerodynamic silhouette and wheel selection ranging from 18 to 20 inches. Delivering 208 horsepower with the help of standard 4MATIC all-wheel drive, the GLA morphs into the most powerful four-cylinder SUV on the market in AMG 45 trim, which is rated at 375 horsepower. What about cargo? An available power liftgate gives access to a 421-litre trunk that triples in size when folding the rear seats.
