Mercedes-Benz GLA 250 4MATIC 225 vs Mercedes-Benz GLS 450

Over a standing quarter mile on dry asphalt the Mercedes-Benz GLS 450 is the quicker car, covering it in 14.19 s at 99.6 mph against the Mercedes-Benz GLA 250 4MATIC 225’s 14.51 s — a margin of 0.31 s. To 60 mph the Mercedes-Benz GLS 450 takes 5.69 s and the Mercedes-Benz GLA 250 4MATIC 225 6.00 s.

Simulated, not measured — computed from each car’s published kerb mass, rated power and drivetrain, then fitted to its own published acceleration figures. Dry asphalt, 20 °C, sea level, 1 ft rollout.

Questions

Is the Mercedes-Benz GLA 250 4MATIC 225 or the Mercedes-Benz GLS 450 faster?
The Mercedes-Benz GLS 450. Over a standing quarter mile it runs 14.19 s to the Mercedes-Benz GLA 250 4MATIC 225's 14.51 s, a margin of 0.31 s, and it reaches 60 mph in 5.69 s against 6.00 s. These are theoretical times from a physics simulation, not measured runs.
What is the Mercedes-Benz GLA 250 4MATIC 225 0-60 time?
The Mercedes-Benz GLA 250 4MATIC 225 reaches 60 mph in 6.00 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 14.51 s at 94.0 mph.
What is the Mercedes-Benz GLS 450 0-60 time?
The Mercedes-Benz GLS 450 reaches 60 mph in 5.69 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 14.19 s at 99.6 mph.
What trap speed does each car run?
The Mercedes-Benz GLA 250 4MATIC 225 trips the lights at 94.0 mph and the Mercedes-Benz GLS 450 at 99.6 mph at the end of the quarter mile. These are theoretical times from a physics simulation, not measured runs.
Are these real measured times?
No. Every time on this page is produced by a physics simulation, not by a stopwatch at a drag strip. Each car is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it matches its own published acceleration figures — 2 of 2 for the Mercedes-Benz GLA 250 4MATIC 225 and 7 of 7 for the Mercedes-Benz GLS 450. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
