Ferrari has entered the hybrid arena at full throttle. LaFerrari (www.ferrari.com), which was unveiled at the Geneva Motor Show in March, is powered by a 6.3-liter, 789 hp V-12 engine and an electric motor that produces an additional 161 hp. That is a total of 950 hp for a car that is said to weigh less than 2,800 pounds. LaFerrari has a top speed of more than 217 mph. On the company’s test track, this successor to the Enzo posted the fastest lap time of any Ferrari road car ever. Ferrari plans to build only 499 examples, and each is expected to be priced at more than $1 million.
