The 135i Convertible, on sale later in 2008, features BMW's twin-turbocharged 3.0-liter inline six-cylinder engine producing 300 horsepower and 300 lb-ft of torque from as low as 1,400 rpm. With its direct piezo gasoline injectors, twin low-mass turbochargers and air-to-air intercooler, optimum performance and economy is achieved with no loss in engine response. For the 135i Convertible, acceleration from 0-62 mph is accomplished in 5.6 seconds and top speed is electronically limited to 155 mph. Both engines feature on-demand engine coolant pumps that improve fuel economy and reduce parasitic losses for increased efficiency.
Distinctive BMW Convertible appearance
In a mere 22 seconds-even on the move at speeds up to 25 miles per hour-the occupants within the 1 Series Convertible can go from encapsulated comfort to top-down exhilaration. If conditions dictate, the electro-hydraulically-operated softtop can be raised within the same 22 seconds, producing a distinctive silhouette enhanced by long frameless doors. The characteristic features of the BMW kidney-shaped grill, front skirt, door sills and rear skirt are identical to those of the 1 Series Coupe.
The standard softtop is available in either black or taupe cloth, but it is the optional Moonlight Black version which is unique to the 1 Series Convertible. Interwoven with fine shiny metallic fibers, this distinctive top produces a shimmery metallic silver appearance in sunlight. The visual effect enhances the convertible's exciting range of nine colors which includes an exclusive hue: Cashmere Silver Metallic.
A distinctive feature of the 1 Series Convertible is the flared shoulder line which runs parallel to the road. This shoulder line flows from the hood past the A pillar to the trunk lid, forming a surface which encompasses the entire interior, giving the impression of a boat deck.
The view from the rear is influenced by the position of the softtop: with the top lowered, completely concealed in the tail, the look is flat and elegant; the appearance with the top up is broad shouldered. The trunk lid has an integrated spoiler chiseled into the rear end of the car to accentuate the short rear section. On the 135i, an additional lip spoiler provides greater downforce on the rear end at high speeds.
Spacious trunk supplemented by folding seat backs and storage bag. An active couple can carry their gear, regardless of the season, thanks to the generous trunk space offered by the 1 Series Convertible. Two golf bags will fit in the trunk of the new 1 Series Convertible - even with the top down! Lowering the soft top produces a storage space that is 8.48 cubic-feet, which does not include the optional large storage bag that extends into the passenger compartment and can accommodate two snow boards or a golf bag without soiling the upholstery. A zippered opening allows access into the storage bag from within the passenger compartment.
The four standard airbags in the new BMW 1 Series Convertible are designed for the optimum protection of the car's occupants. The advanced frontal airbags are activated in stages in relation to impact severity while the side airbags integrated into the sides of the front seat backrests reduce the risk of injury at chest, hip and head levels in side impact situations. The new BMW 1 Series Convertible also comes with crash-optimized seats with specially padded headrests and backrests designed to reduce the risk of injury in an impact from the rear.
All seats within the 1 Series Convertible are fitted with three-point inertia-reel seat belts and headrests, with the front seat belts str fastened on the frames of the driver's and front passenger's seats, keeping the belt in an optimum position around the occupant's hips regardless of seat height or fore-aft placement. Also, the driver's pedals move back automatically with a predetermined amount of deformation in the event of a frontal collision so that the risk of driver foot injury is reduced. And last but not least, the rear seats come standard with LATCH attachments for child seats.
The new BMW 1 Series Convertible is equipped with a roll-over sensor, which continually monitors the vertical and horizontal movements of the vehicle. As soon as the sensors register the danger of the vehicle rolling over, two roll bars are extended in fractions of a second from their storage areas behind the rear headrests. Simultaneously, the front-seat-belt tensioners and the head airbags are activated. Further roll-over protection is offered by the optimized stability of the A pillar and windshield frame.
