Mercedes-Benz has unveiled a new generation of the S-Class. The big sedan lands at dealerships next spring in S500 and S580 guises, and with more technology than you'll ever need.

Nissan's next-generation Frontier has been spotted for the first time. It's coming later this year and at launch will exclusively offer the 3.8-liter V-6 that Nissan added to the 2020 Frontier. No, the engine isn't related to the 3.8-liter twin-turbocharged V-6 in Nissan's GT-R.

Ram has only just unveiled the 702-horsepower 1500 TRX, but Hennessey has already announced a much wilder version. Hennessey's TRX will feature a Hellephant engine spitting out over 1,200 horsepower and spinning six wheels.
