Edmunds tests hundreds of vehicles a year. Cars, trucks, SUVs, we run them all, and the numbers always tell a story. With that in mind we present "Edmunds Track Tested," a quick rundown of all the data we collect at the track, along with comments direct from the test drivers. Enjoy.
Enthusiasts will tell you that the BMW 3 Series has lost its way; that the new car is too big, too powerful, too plush and certainly far too expensive. But it doesn't have to be.
Tucked neatly into the bottom rung of BMW's 3 Series lineup is the $33,475 2013 BMW 320i. Like the 328i, the 320i uses a turbocharged, 2.0-liter four-cylinder engine, but in the 320i it's tuned to develop 180 horsepower and 200 pound-feet of torque instead of the 328i's 240 hp/255 lb-ft output.
Available with either an eight-speed automatic or a no-cost six-speed manual, the 320i also returns 28 mpg in combined driving compared to the 328i's 26 mpg combined.
So it not only saves you some gas, it also saves you about $4,000 to start versus the 328i. Of course, the big question is, does it still feel like a real 3 Series with only 180 hp on tap? We took it to the track to find out.

RPM @ 70: 1,900
Acceleration: There's nearly a full second between slowest (default Comf + Drive) and quickest (Sport + Auto-upshift manual) modes, and yet not quite enough power to spin the rear tires with traction control shut off. Upshifts in any mode are exceptionally smooth and reasonably quick. The car will still upshift at redline, even in Manual mode. The turbocharger doesn't make itself known at all: no lag, no swell of torque and no whine/whistle. Most folks would never know.
Braking: Medium-firm pedal from first to last stop. Good heat capacity in the brakes, as the best stop came on the third stop. Arrow-straight, little dive, no drama.
Slalom: While this isn't an analogous experience to every 3 Series that preceded it, it is a nimble car with high limits and quick reflexes. It retains only a modicum of feedback for driver involvement: The steering isn't what it once was in terms of feel, nor does one "drive it off the rear tires" like before. What it is now is well-balanced and competent rather than invigorating and involving.
Skid pad: The throttle offers just enough response to be useful in transferring weight front/rear and the steering is surgically precise. Highly polished and poised.
