Lots of cars share components. But for these ostensibly different cars, the differences are only skin-deep. Born out of platform-sharing partnerships or badgineering, underneath the sheet metal these 10 pairs of cars are alike.
Subaru BRZ / Scion FR-S
The most hyped twins today are the new sport coupes built through the collaboration of Subaru and Toyota. You have to study these cars closely to find anything but a name badge to tell them apart: Their front bumper covers are slightly different, and the Scion's got a little badge that says "86" on the front fenders (a nod to the AE86 rear-drive, ultrafun Toyota Corolla coupe of 1983 to 1987). Inside, the auxiliary gauges are slightly different sizes, but the cars share a unique flatter version of Subaru's 2.0-liter flat-four engine that makes 200 hp with Toyota's fuel-injection system.
Actually, this one is a three-part rebadging job. Overseas, the Scion is called the Toyota GT-86, or just Toyota 86.
