"         The character of BMW&amp;#039;s 335is is decidedly different from that of the 335i. It starts with the older but more potent N54 twin-turbocharged inline-6 powerplant (the standard 2011 335i is equipped with a single twin-scroll turbo). Power is increased thanks to direct injection and VANOS, BMW&amp;#039;s name for variable valve timing, on both the intake and exhaust cams. With these technologies, engineers were able to raise the compression ratio to a rompingly high 10.2:1.   To combat heat during track driving, the &amp;quot;is&amp;quot; is fitted with a heavy-duty radiator fan and two extra heat exchangers. One, an engine oil cooler, and the other, a secondary coolant radiator. They are located ahead of each front wheel. This necessitated a new M3-esque front fascia with larger air openings.   A performance-oriented tune adds launch control to cars equipped with the dual-clutch transmission, and both it and the 6-speed manual-equipped version (like our test car) receive an overboost function that will temporarily raise torque from 332 lb.-ft. to 370. Full throttle runs sound especially choice thanks to a revised, high-flow exhaust system.   Along with these mechanical changes, the 335is is equipped with a smattering of &amp;quot;M&amp;quot; parts, such as the steering wheel, seats, shift knob and pedals.   Driving the car, you quickly notice the added power and throatiness of the exhaust. Steering is heavy, but becomes transparent when driven through a favorite set of turns. The starting price may be high for the casual driver, but is a deal when compared to the M3. To the layperson, the changes and the extra letter in the 335is&amp;#039; designation wouldn&amp;#039;t be obvious, and that&amp;#039;s just fine. Its differences are meant for someone who&amp;#039;ll properly exercise it on the track and twisty roads.       2011 BMW 335is       List price     $49,650       Price as tested     $57,450       Curb weight     3560 lb       Engine     3.0-liter twin-turbo I-6       Transmission     6-sp manual       Horsepower     320 bhp @ 5900 rpm       Torque     332 lb-ft @ 1500 rpm       0-60 mph     4.6 sec       0-100 mph     11.2 sec       0-1320 ft (1/4 mile)     13.2 sec @ 106.2 mph       Top speed     150 mph*       Braking, 60-0 mph     116 ft       Braking, 80-0 mph     204 ft       Skidpad     0.93 g       Slalom     69.0 mph       Our mileage     est 19.0 mpg       EPA city/hwy     18/26 mpg       * Electronically limited.
