2011 BMW 335is
The is ("i" for injection, as in fuel, and "s" for sport, as in fun) follows a tradition of s-badged sport-enhanced models, including the 320is, 325es, 325is, 535is, and most recently, the X5 4.6is and 4.8is.
This 335is features a massaged version of the N54 turbocharged inline six and an array of M Sport accoutrements to put it on a tier above the current 335i.
In spite of the recent revelation of BMW's next-generation turbo six (the single-turbo N55), the 335is will employ the more familiar N54 twin-turbo. Precision fuel injection, Double-VANOS stepless valve timing, and an advanced Digital Motor Electronics (DME) control system collaborate to push peak power from 300 to 320 hp, and torque from 300 to 330 lb-ft. There's also an overboost function that briefly kicks the peak torque to a massive 370 lb-ft under hard acceleration in "certain circumstances." (We love those kinds of circumstances.)
Other engine upgrades are placed to compensate for the increased performance, like an additional radiator behind the left side bumper intake, an oil cooler behind the other intake, and stiffer engine mounts.
The 335is comes with a standard six-speed manual transmission, or, for the first time on a non-M car, the seven-speed DCT automated manual (which includes a launch control function) as an option.
While all 3 Series coupes and convertibles have received a midlife facelift for the coming model year-including massaged body panels and front and rear light clusters-M Sport styling cues vistually set the 335is apart from its more pedestrian siblings, including a front fascia and side skirts designed to move more air to critical locations, a rear fascia with diffuser, standard Shadowline window trim, gloss-black side mirrors, 335is badges on the front quarters, and standard 18-inch wheels (19s are optional). On the inside, the M Sport upgrades include the steering wheel, sport seats, an anthracite-colored headliner, stainless steel pedals, 335is branding on the dashboard and tachometer, and M-branded sill plates, dead pedal, and gearshift knob.
