I love fire-breathing, octane-swilling big blocks as much as any red-blooded car nut, but I know that dino juice won’t last forever. Ford knows it, too. That’s why they have their engineers slaving away to make the fleet more fuel efficient. The Start concept puts fuel economy above all else. The funky little jellybean rocks a 1-liter, three-cylinder EcoBoost engine that will soon appear in production vehicles. According to Ford, the engine will offer the same horsepower and torque of a larger four-cylinder, but will sip less fuel. The car itself is an experiment in creating a simple, endearing design. I like it. Hit the jump for more photos.
