Alpina takes a unique approach to performance. Rather than sacrificing itself at the altar of handling, the tuning house takes a more relaxed approach, putting comfort before hot-lap dominance. The latest product of that formula is the D5 S, the fastest diesel production car in the world.

Chevrolet has revealed its 2018 Equinox will be offered with three engine options, including a new 1.6-liter diesel. That diesel option will have a cruising range of up to 577 mi (928 km) per tank​ and be EPA rated at up to 39 mpg (6 L/100km) on the highway.

​Siemens first revealed its eHighway concept back in 2012, where a hybrid diesel/electric truck moving down a stretch of road could raise its pantograph to overhead power lines and roll along on electric power only.

The folks Down Under are partial to a pickup, and Ford would argue the range-topping Ranger Wildtrak is the best pickup you can buy. With a luxurious interior, plenty of off-road gear and a ruggedly handsome face, it certainly looks good on paper. But does it deliver in the real world?

BMW has announced the new M550d xDrive. With four turbochargers boosting its six-cylinder engine, the flagship of the 5 Series range is the most powerful production six-cylinder diesel car ever built.

It might be under French control now, but the move from General Motors to Peugeot ownership hasn't slowed the product offensive from Opel. The Crossland X aims to cash in on the massive compact SUV market, with plenty of customisation options and a range of compact, efficient turbocharged engines.

When it comes to delivery vans, there isn't usually much to get excited about. The one-off Nissan NV Cargo X is an exception to the rule. With a proper off-road suspension, Cummins diesel engine and bright sticker kit, it'll get your package delivered – no matter the destination.
