The old twin-turbo inline-6 lives on, however, in the new 335is coupe and convertible. This sport-tuned version produces 320 horsepower and 332 pound-feet of torque, with an overboost function that can briefly bump torque up to 370 lb-ft. We're guessing that the 335is will hit 60 mph in just a hair under 5 seconds. In many ways bridging the gap between 335i and M3, the 335is also features a sport-tuned suspension and exhaust, an aerodynamic body kit, sport seats and a chunkier steering wheel.
Otherwise, the 3 Series remains one of the most desirable vehicles on the road. Quite simply, no other entry-level luxury model can match the Bimmer's exquisite combination of athletic handling and premium ride comfort. Even the base suspension setup is more capable than most, while the Sport package gives it sports-car-grade cornering capabilities without the slightest hint of impact harshness. This sophisticated dual nature has often been imitated, but never duplicated.
Standard equipment on the 328i models includes 16-inch wheels, heated side mirrors, rain-sensing wipers, automatic headlights, foglamps, "leatherette" premium vinyl upholstery, automatic climate control and a 10-speaker sound system with CD player, HD radio and an auxiliary audio jack. The coupe comes with a sport-tuned suspension, while the convertible gets a power-retractable hardtop, an upgraded stereo and power front seats with driver memory. Both two-door 328i's get 17-inch wheels and adaptive xenon headlights.
In addition to their different engines, the 335i and 335d add 17-inch wheels, adaptive xenon headlights (sedan and wagon), a sunroof (not convertible) and power front seats with driver memory. The 335is coupe and convertible get a more powerful engine, a sport-tuned suspension, 18-inch wheels, a special body kit, sport seats and a sport steering wheel.
The Premium package adds leather upholstery (heat-reflective in the convertible), auto-dimming mirrors, Bluetooth connectivity, BMW Assist telematics and, on 328i models, a sunroof and power seats with driver memory. The Sport package (all but 335is) specifies the sport-tuned suspension for convertibles, sedans and wagons (the coupe already has this as standard) and all get larger wheels, the sport seats and steering wheel, and special "Shadowline" exterior trim. The M Sport package adds many of the 335is features.
The Cold Weather package adds heated front seats, retractable headlight washers and fold-down rear seats (though the latter are unavailable in the convertible). The Convenience package adds adaptive xenon headlights (328i), front and rear parking sensors, power rear sunshade (not convertible or wagon), keyless ignition/entry and manual side window shades (sedan and wagon).
The 328i features a 3.0-liter inline-6 that produces 230 hp and 200 lb-ft of torque. A six-speed manual is standard and a six-speed automatic is optional. In performance testing, we clocked a 328i sedan with the manual from zero to 60 mph in 6.4 seconds, while the heavier convertible is a few tenths of a second slower. According to the EPA, fuel economy is an estimated 18 mpg city/28 mpg highway and 22 mpg combined. The wagon and/or all-wheel-drive models are a smidge worse.
The 335i features a 3.0-liter turbocharged inline-6 that produces 300 hp and 300 lb-ft of torque. It gets the same transmission choices as the 328i. Although this engine is new, its power numbers are the same as before, so we doubt its 0-60 times would be much different than the approximate 5-plus-second times we recorded in the past. Fuel economy is now actually slightly better than the less powerful 328i, at 19 mpg city/28 mpg highway and 22 mpg combined.
The 335is features a more powerful version of the 335i's previous twin-turbocharged inline-6, and produces 320 hp and 332 lb-ft of torque. There is a temporary overboost function, however, which bumps torque up to 370 lb-ft. A six-speed manual is standard, and a seven-speed automated dual-clutch manual known as DCT is optional. The 335is should be even quicker than the 335i. BMW's estimated fuel economy is 18/26/21 with the manual and 17/24/19 with DCT.
Most of the upper trim and package add-ons are also available as à la carte options. Other items include a hard-drive-based navigation system with the iDrive controller, active cruise control, an active steering system (335i and 335is only), a heated steering wheel, paddle shifters for the optional automatic transmission, satellite radio, an iPod adapter and a Harman Kardon surround-sound audio system.
In government crash tests, the sedan and wagon received four out of five stars for frontal collision protection and five stars for side protection. The Insurance Institute for Highway Safety gave the 3 Series the top rating of "Good" in its frontal-offset crash test. The 3 Series also scored a "Good" for side crash protection except for the convertible, which received the second-lowest "Marginal" score.
