Powerful Efficiency: 20 Sporty Turbos

2018 BMW 230i Coupe
Starting MSRP: $34,800
You don’t need a BMW with an M in its name to get a furious fully-boosted ride. The 2 Series base trim is called Sport Line, and it includes an intoxicating twin-turbo 248-horsepower 2.0-liter TwinPower four-cylinder powerplant. The big fork in the road is the transmission. The 230i comes with an 8-speed automatic with plenty of pushbutton sport modes. It returns 24 mpg city /35 mpg highway / 28 mpg combined fuel economy. Work the gears yourself via the no-cost option 6-speed manual transmission and give up 3 mpg (21 / 32 / 25). Manual gearboxes used to deliver better mpg, but advanced computer-controlled automatics have taken the lead in many cases.
