Today, the National Highway Traffic Safety Administration (NHTSA) investigates Tesla Autopilot after a fatal crash, we look at buyback amounts for Volkswagen TDI diesel cars, and Elio Motors builds its first test car. All this and more on Green Car Reports.

How does a new 2016 Tesla Model S compare with an original version in terms of price, features, and overall value?

What will owners get for illegal Volkswagen diesel cars in buybacks? The answer depends on several factors.

Mercedes-Benz is reportedly considering its own sub-brand for electric cars, similar to BMW i.

Elio Motors finally builds a car. A test car, that is.

Volkswagen thinks it can fix the 85,000 illegal diesels equipped with 3.0-liter V-6 engines relatively easily.

The National Highway Traffic Safety Administration will investigate Tesla Autopilot after a fatal crash in which a Model S running the system hit a semi trailer.

The NHTSA is also urging drivers of 313,000 Honda and Acura cars to park their vehicles immediately, due to extremely high risk of exploding Takata airbags.
