It's one of the world's dream routes: from San Francisco to Los Angeles, hugging the coastline. And, what's more, in a BMW 335d with Variable Twin Turbo and output of 286 hp. The Americans were amazed; they've never experienced a diesel like this - clean, sporty and fast. Autumn will see its launch on the US market. We gave the Californians a taster of what is to come. Connoisseurs and trade experts alike were thrilled: "Great car!"
