Who builds the strongest engines - Toyota, Land Rover, or Mercedes?

Well, to find out, we’re pushing our £2,000 Toyota Land Cruiser, Land Rover Discovery and Mercedes ML to the limit to see which lasts the longest.

They’re no longer road-worthy, but which can last the longest when pushed to full throttle? First off, let’s take a closer look at the contenders:

Starting with the Discovery 3, it’s powered by a 2.7-litre V6 that produces 190hp and 440Nm. It’s equipped with a 6-speed manual and weighs 2,419kg. It was first released in 2005, we bought it for £1,500, and it currently has 256,000 miles on the clock.

Up next is the Mercedes ML. There’s a 2.7-litre inline-5 turbo diesel under the bonnet, and this produces 163hp and 400Nm. It’s equipped with a 5-speed automatic gearbox, weighs around 2,100kg, and was released in 2005. We bought it for £1,800, and it has 140,000 miles on the clock.

Finally, we come to the Land Cruiser. It’s powered by a 4.7-litre V8, and this puts down 235hp and 434Nm. It rolls up with a 4-speed automatic gearbox, and it weighs 2,260kg. It was originally released in 2002, and although it was originally bought for £5,000, it’s only worth around £2,000 now. To date, it’s run around 282,000 miles.
