I’m not really a motoring journalist, never written a test drive report, never had a long-term test car to swan around in. But I have written quite a lot about fuels, especially alternative fuels, and more recently written several pieces for Diesel Car magazine.
Most of these have been for the EcoCar pages in the magazine, and all are about some aspect of technology used in cars, rather than about the whole vehicle. Samples below:
Used EVs (PDF)
Car Hacking (on Diesel Car website)
