The Ram 1500 now has a twin-turbo 3.0-litre inline six-cylinder engine, available in two tunes.

The Standard Output engine makes 313kW and 635Nm, while the High Output tune is good for 403kW and 707Nm.

Both utilise an eight-speed torque converter automatic transmission and a part-time 4WD system.

The Ram 1500's interior is extremely spacious, with generous seat sizing and large storage spaces in true American style.

Materials range from cloth to leather and involve styled trim in higher variants, but Australian models get upmarket versions of much of the 1500's trim regardless of variant.

The Ram 1500 has a generous seating arrangement with two large, comfortable seats in the front in a traditional layout, while the second row is a wide bench seat with space for three.

The second-row seat can be folded up to make space for storage, too.

The Ram 1500 has two engine options, a Standard and a High Output version of the Hurrican inline six.

With the Standard Output, the Ram 1500 should hit 100km/h in about six seconds, but the High Output should knock about half a second off that.

Top speed should be not much more than 160km/h, but hitting those speeds on anything other than a drag strip or autobahn would be anxiety-inducing.

The Ram 1500 has a 98-litre fuel tank in most variants, able to be filled with regular unleaded petrol and consumed at a claimed 10.7L/100km rate.

Theoretically that should mean around 900km on a tank, but realistically you should plan for between 700km and 800km.

The top-spec Limited version of the 1500 has a larger 125L tank, and needs premium unleaded for its more powerful engine. It sips more fuel at 11.8L/100km but should still manage close to 1000km per tank.
