The BMW i8 occupies a unique niche in the market; no other sport coupes blend sexy styling with up to 15 miles of all-electric running along with their performance credentials.
Other competitors, while equally pricey and fast, differ significantly.
The Tesla Model S offers superior performance in its highest models, but while sleek, it's a four-door hatchback sedan, not a sport coupe (let alone its lack of gull-wing doors).
Still, Tesla buyers may be more attuned to a light plug-in hybrid coupe with electric running than are those who opt for more traditional sports and luxury models.
Two examples are the Audi R8 and Porsche 911, in all their various permutations, which are heavier and offer only combustion engines.
Similarly, BMW's own four-seat 6-Series coupe—perhaps even BMW's Z4 two-seater—may compete across the showroom floor.
But the i8 remains largely a one-of-a-kind coupe.
