A hundred or 120 miles, you say? Isn't that peanuts compared with the Tesla Model S, which will offer perhaps 160 miles with its base version, and 300 miles for the premium model? Yes, of course -- but the Tesla is a much more expensive car. The 160-mile base Tesla is $57,400, and the 300-mile version is $77,400. Add all the options and we're talking around $100,000. In other words, the Chevy Spark, while obviously being a much smaller and simpler car for sure, will arrive at approximately half the price of the most basic Tesla Model S. Then subtract the same $9,000 in tax incentives, and we may be comparing a $20,000 car with a $50,000 car. That's 60% less. These two cars have something in common, but they aren't the most direct competitors.
