TESLA’S BIG TEST: Tesla Motors will start selling its all-electric Model S sedan Friday. It’s a make-or-break car for the company, which is aiming for a mainstream customer. Tesla’s only previous model was a high-end sports car.
THE DETAILS: The Model S is a five-seat sedan that can go up to 300 miles on an electric charge. It has no backup gas engine.
WILL IT SELL?: Tesla says it expects to sell 5,000 Model S sedans worldwide this year and 20,000 next year. But some analysts say its price tag — starting at $49,900 — will limit sales.
