The 428i is powered by a 2-liter turbocharged four-cylinder engine that produces 240 horsepower and 258 pound-feet of torque. It provides excellent acceleration -- 0 to 60 mph zips by in as little as 5.6 seconds for the xDrive Coupe -- while also providing excellent fuel economy.
A 428i rear-wheel drive coupe equipped with the eight-speed automatic returns 23 mpg city and 35 mpg. Even the heavier all-wheel drive 428i xDrive convertible makes 21 mpg city and 33 mpg highway, which represents the worst mileage of all the 428i trim levels.
I spent a very pleasant week driving the 428i Convertible and can attest to handling and braking that are in a league with very few competitors, especially if you opt for the relatively inexpensive Track Handling Package. The adaptive M suspension and M sport brakes give the 428i an enthusiast-pleasing driving dynamic that few other cars offer.
Unlike many manufacturers, the 428i still offers a manual gearbox in the two-door coupe. While the eight-speed automatic is truly marvelous, the connection of driver and machine that manually shifting through the gears offers in the 4 Series is unforgettable.
My review vehicle, the all-wheel drive 428i xDrive convertible, might qualify as the Swiss army knife of cars. It's a great all-weather vehicle that handles copious amounts of snow and sunshine with equal grace.
