Hot on the tail of the VW emissions scandal, Australia will next year tighten diesel emissions standards.
Diesels typically have good fuel economy, but hot on the heels of the Volkswagen affair, Australia is set to tighten the rules for diesel car emissions - which will put a dent in engine performance.

The VW emissions scandal is an opportunity to forge ahead with fuel cell technology for cars.
The emissions scandal has already taken its toll on Volkswagen.
It's likely that many people knew Volkswagen was cheating on emissions tests, including the engineers who built the 'defeat device'. But why did no-one at the car maker blow the whistle?

Eleven million cars worldwide could be affected by the scandal.
Volkswagen's cheating allowed its vehicles to pass rigorous emissions testing, giving customers maximum driving performance at the cost of the environment and our health.
