Today on Green Car Reports: An executive's statement sparks conflict between Hyundai and Tesla, the EPA wants carmakers to verify gas mileage with road testing, and BMW and Samsung plan to share battery tech with other companies. All this and more on Green Car Reports.

Apparently sick of "range anxiety," a Chinese Tesla Model S owner buys a series of charging stations, and seeks sites to install them using social media.

Audi celebrates 25 years of fuel-efficient TDI diesel engines.

BMW and Samsung plan to share electric-car battery technology with other companies.

The EPA wants carmakers to verify gas mileage with road testing, too.

Hyundai expects gasoline suppliers to invest in hydrogen infrastructure.

That's not all that was said on the subject, though. A Hyundai executive suggested the U.S. government was funding Tesla's Supercharger stations, provoking an angry response from the electric-car maker.

As we previously suspected, the 2014 model year will be the last for the Nissan Cube tall wagon.

Finally, a car seat that monitors the driver's heart rate and determines whether a driver is falling asleep. That's not creepy at all.
