The first day of the 2018 North American International Auto Show is in full swing and there's been plenty of debuts already. One of the big reveals was the next-generation Ram 1500. This is one of the most important vehicles for Fiat Chrysler Automobiles, and so far it's managed to impress the audiences in Detroit.

Another star has been the slightly smaller Ford Ranger pickup. Sitting in the mid-size category, the new pickup will soon be battling it out with the likes of the Chevrolet Colorado, GMC Canyon, Honda Ridgeline, Nissan Frontier and Toyota Tacoma.

There was luxury on show, too. Mercedes-AMG introduced the first models from its new 53 series: the CLS53 and E53 Coupe and Cabriolet. Each of them come with a powertrain delivering V-8 power coupled with the fuel consumption of a 6-cylinder.
