The 2018 Mercedes-AMG GLA45 is a mildly-refreshed pocket rocket

If the standard GLA250 doesn't do it for you, perhaps the GLA45 is more your speed.

Power comes from a 2.0-liter I4, like the GLA250, but that's where the similarities end.

Here, output is a whopping 375 horsepower and 350 pound-feet of torque.

Thanks to all-wheel drive and a seven-speed transmission, the GLA45 rockets to 60 mph in just 4.3 seconds.

Like the GLA250, the GLA45's updates include small aesthetic tweaks inside and out.

Top speed is 155 mph, but the AMG Dynamic Package Plus can bump that up to 167.

The inside remains a positively sporty affair, with standard sport seats and plenty of AMG badging throughout.

You can add even more color and doodaddery to the GLA45 with the new AMG Performance Studio Package.

The GLA45 goes on sale this summer. Pricing has not yet been announced.
