22nd generation. For over forty years, from 1975 to the present day, twenty-two versions of the BMW 3 Series Sedan have been replaced to meet the needs of a crowded market segment. It is the D segment, the one where the medium-large sedans find their place. A sector in which the three volumes has always been at ease, often acting as a protagonist.
BMW 3 Series Sedan: design and interior
The BMW 3 Series Sedan is a sedan with elegant shapes and overall dimensions. Less than five meters long (471 cm) for about 1,500 kg of weight, but still comfortable, especially if you travel in four and not in five. The trunk has a capacity of 480 liters but, if necessary, lowering the three seats of the rear seat, space increases consistently.
Externally, the three Bavarian volumes are characterized by elegant lines and six different versions: Base, Advantage, Business Automatic, Sport, Luxury and MSport. Versions that differ mainly from the front (the more aggressive is the MSport, the rich and luxurious the Luxury) which however does not renounce the double kidney grille, a trademark in BMW. The double adaptive LED headlights with Cornering Light, with a sharp cut and with horizontal development are also very beautiful, also available with Laser light technology.
The interior of the BMW 3 Series Sedan is characterized by the extensive use of Vernasca leather for the seats, which can alternatively be replaced with fabric, eco-leather or Alcantara (exclusively for the MSport version). For the rest, the dashboard reflects the clean style that BMW has chosen for its most recent cars. As well as the screens, always two and in sizes of 12.3 and 10.25 inches.
The BMW 3 Series Sedan is available on the market with five different engines, two petrol and three diesel. Starting from the petrol-powered engines, 320i and 330i, we note that they are characterized by an identical number of cylinders (four) and displacement (1,998 cubic centimeters). The main differences are in the horsepower: the 330i takes the 320i 258 hp to 185, and the maximum torque, 400 Newton meters to 300, always at the expense of the 320i. If then the top speed values are almost identical (the 330i reaches 250 km per hour while the 320i stops at an altitude of 240), the same cannot be said for the acceleration capacity: from 0 to 100 in 7.1 seconds for the 2.0-liter 320i, while 5.8 are those used by the four-cylinder 330i.
Some differences also between the diesel engines, 318d, 320d and 330d. If the first two can boast four cylinders and 1,995 cubic centimeters of displacement each, the 330d is characterized by a higher number of cylinders (six) and by a displacement that reaches 2,993 cubic centimeters. Differences even on horsepower and maximum torque: we start from the 150 hp and 320 Nm of the four-cylinder 318d, to reach the 265 hp and 580 Nm of the 3.0-liter 330d. In between, the 190 hp and 400 Nm of the other four-cylinder, the 2.0-liter 320d.
Not surprisingly, the BMW 3 Series Sedan with 330d diesel engine is the most powerful of the lot powered by diesel (250 km / h top speed and 0-100 acceleration in 5.5 seconds). The performance of the two four-cylinder engines is more similar (226 km/h and 240 km/h top speeds for 318d and 320d, while accelerating from 0 to 100 respectively in 8.4 and 7.1 seconds).
Price and consumption
So much variety in prices. It starts from the basic version (with 318d engine), on the market starting from 38,700 euros. More expensive the other versions, with a price ranging between 41,650 euros for the Advantage and 47,750 for the MSport. The same goes for the engines. Compared to the 318d, we need to add “only” 3,750 euros to get the 2.0-liter 320i, but a good 11,400 euros to enjoy the performance of the 330d six-cylinder.
The same applies to fuel consumption and emissions, where it goes from 5.8-6.0 liters of petrol per hundred kilometers (and 132-136 grams of carbon dioxide per thousand meters) of the 330i, to 4.2-4.5 liters of diesel per hundred kilometers (and 113-122 of carbon dioxide per thousand meters) of the 318d.
