It’s encouraging to see car manufacturers look for alternative fuel sources to power their vehicles. This particular concept by Saab comes equipped with an ethanol guzzling 2.8L twin-turbocharged V6 that can get you from 0 to 100kph/60mph in 4.2 seconds. Even cooler, the car has no doors, rather, the entire top canopy section of the car opens up, making it one of the most unique designs out there. Sadly, the car is still on concept stage. But one can still dream.
