RDSport RS35 Biturbo Here is a good alternative to a V8 powered BMW M3. RDSport offers now extra power to already well performing BMW 335i. Engine upgrades include electronic modifications, free flowing intake and a larger intercooler for more air.

These modifications increase the horsepower to 414 horsepower and 404 lb-ft of torque. That’s more than the V8 powered M3.

RS35 Biturbo sits 25 mm lower in the front and 20 mm in the rear. Exterior upgrades include carbon front bumper with larger air intakes and new fog lights. Side skirts and revised rear apron with quad exhausts add a more aggressive look.

Interior is also upgraded with aluminum pedals, aluminum hand brake cover, logo carpet set and upgraded speedometer with logo. No information on the pricing or performance numbers. More details below in the press release.

Press release:

or those wishing to increase the performance of an already stellar platform, RDSport offers the RS35 Biturbo.

The first impression you get of the car is its lower, more aggressive stance courtesy of a Chassis Kit consisting of new custom-valved Bilstein struts, stiffer springs and anti-roll bars. The vehicle now sits 25 mm lower in the front and 20mm lower in the rear with a decidedly more stable ride. Filling the fenders are lightweight, 20″ RD2 Monoblock wheels or the optional 20″ RS2 multi-piece wheels, shown. Tires are P Zero Nero’s supplied by Pirelli, our development partner.

Engine performance includes electronic modifications to increase boost and optimize fuel and timing. A free-flowing intake and a larger, more-efficient intercooler help supply enough air. Exhaust gasses run through a larger exhaust that terminates in stainless sport silencers with quad tips. These modifications result in an increase in horsepower and torque to 414 bhp and 404 lb/ft - more than the V8 powered M3!

The under hood area is finished with a blue engine cover with RDSport crest. These numbers are merely the result of a long development period including TUV homologation. Any tuner can offer a black box upgrade for the vehicle, but how many can say that their modification has been tested and can include the upgraded speedometer and wheels and tires that the homologation requires.

Bodywork is an evolution of RDSport’s signature Tornado aerodynamics. The revised carbon front bumper offers larger openings for better engine and brake cooling with an exposed carbon housing for fog lights. Deeper side skirts and revised rear apron with quad exhaust cut outs add to the aggressive look while a roof and trunk spoiler smooth out the airflow over the car.

Interior upgrades include the RS Pedal Set in machined aluminum, aluminum hand brake cover, logo carpet set, the aforementioned upgraded speedometer with logo and RDSport crests in the steering wheel and shift knob.
Each complete vehicle built by RDSport includes a vehicle ID badge and VIN specific build sheet.
