It would be a mistake to count out the internal-combustion engine as yesterday's technology, soon to expire in a puff of exhaust gas. Electrification is coming, but meanwhile engineers have offered more innovation for the venerable gas engine in the last three years than they did in the previous 20. The result is 40 mpg on the highway, from four-cylinder power plants with the same performance as older V-6s or even V-8s.
