Mercedes calls the GLS the S-class among SUVs—its rich appointments and power earn it a 2017 10Best award. Its three rows offer room for seven; the interior has leather, wood, and options such as an air-ionization system. The GLS450 has a 362-hp twin-turbo V-6; the GLS550 has a 449-hp twin-turbo V-8. For economy, the GLS350d has a 255-hp diesel V-6. Each model has all-wheel drive and a nine-speed automatic. Safety tech includes cross-wind assist, collision-prevention assist, and brake assist.

Normally, stating that a new or updated car is just like its predecessor kind of saps the life out of its “newness.” Take the 2017 Mercedes-Benz GLS450, for example. Its close kinship with last year’s GL450 may not be exciting, but it is a good thing, as that model represented the ideal intersection of price, performance, and fuel economy in the four-model GL-class lineup.

The GLS450’s new transmission is dubbed 9G-Tronic. Its first seven gears sport shorter ratios than all seven speeds in the old transmission.

The GLS450’s spicier gearing enabled it to reach 60 mph 0.2 second quicker and post snappier 30-to-50-mph and 50-to-70-mph passing times. Some credit for this specific GLS450’s extra zip could be attributed to its lack of optional extras, which made it weigh 207 pounds less than that 2015 GL450.

A straighter line can be drawn between the new transmission and the GLS450’s enhanced fuel economy. The two extra gears, both of which are taller than seventh gear in the old transmission, are responsible for nudging the GLS450’s EPA highway fuel-economy estimate northward by 1 mpg, to 22 mpg. (The city estimate remains 17 mpg.) We saw a bigger improvement, as the 18 mpg our GLS450 notched over a few hundred miles topped the 2015 version by 2 mpg. Better still, the 9G-Tronic’s tall gearing keeps engine revs low at highway speeds, and it behaves nearly flawlessly in the default Comfort mode, save for a tendency to select too high a gear when downshifting unless the throttle is really booted. There is a Sport mode, but it’s slightly too eager, waking up the transmission as though one of those jitter-inducing energy drinks often found at minimarts were poured into the electronics. Lower gears are feverishly held, even at a steady cruise, and first gear is used when accelerating from a stop (second is used in Comfort mode in the interest of smoothness). If you absolutely have to make it to soccer practice on time, use this setting.
