The most similar vehicle to the 2016 BMW i8 may be the now-discontinued Porsche 918 Spyder, which cost about eight times as much as BMW's $135,000-and-up coupe.
Other competitors differ in significant ways, though they have to be fast and expensive.
More traditional sports cars include the many models of Porsche 911 and the raucous, heavier Audi R8.
Perhaps BMW's own 6-Series coupe, with capacity for four—perhaps even its Z4 two-seater—may compete across the showroom floor.
But all are considerably larger and heavier, and their conventional powertrains may rule them out for some buyers.
The most likely competitor is actually the Tesla Model S, a five-seat, four-door electric luxury hatchback that runs on battery energy alone.
Still, Tesla buyers are likely more attuned to a light, forward-looking plug-in hybrid coupe with high energy efficiency than are those of more traditional sports and luxury models.
