Diesel

Diesel has traditionally been the fuel of the maritime industry, which makes the absence of a diesel outboard engine even more puzzling. Production of the 50 hp Yanmar Dtorque 111 turbo-diesel has begun and the benefits over traditional outboard engines seem overwhelming.

The Land Rover Discovery might look like a softer car than the one it replaces, but a stunt has proved it's still a capable vehicle. A standard Discovery has pulled a 110-tonne road train through the Australian Outback, upping the ante over the train-towing stunt from Land Rover last year.

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 new Hyundai i30 hasn't been around for long, but engineers in Seoul have frantically been working to expand the range. Along with the first N Performance model, the i30 has been turned into a slick, four-door Fastback, designed to mimic more expensive four-door coupes from Audi and BMW.

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?

Recent setbacks haven't stopped Volkswagen from improving its impressive lineup. Having treated the Golf to a tech injection, it has overhauled the Polo. It might serve as an entry point to the VW range, but the Polo packs a range of features passed down from its big brothers.

GM has come under fire for allegedly installing defeat devices on over 700,000 vehicles with Duramax engines. A class action lawsuit argues GM and Bosch knowingly sold cars tuned to emit illegal amounts of nitrogen oxide when outside the test environment.

"Dieselgate" might be winding up for VW, but investigations into diesel emissions cheating are just getting started elsewhere. Following news Daimler is being investigated in Germany, the US DOJ has filed a civil suit against Fiat Chrysler for failing to correctly disclose emissions control devices.
