<< Prev Page 3 of 3  The interior of the BMW 4 Series Convertible blends sporting intent and exclusivity to stylish effect. An approach known as layering - the clever utilization of space through the structuring of lines and surfaces into layers - provides a natural canvas for the hallmark BMW driver focus, but is careful not to exclude the front passenger from the action. All of the controls are arranged ergonomically around the driver to provide optimum access to all functions. A sports steering wheel, crystal-clear circular instruments in black panel look and the freestanding, flatscreen iDrive monitor, the iDrive Touch Controller - all within easy reach on the center console - underline the sense of functional elegance. The dynamic horizontal lines of the instrument panel extend into the optional two-tone door and side panel trim. This is enhanced by the retractable hardtop cover to create an exclusive "boat deck" look. The interior design wraps around the driver and front passenger in an unbroken sweep and lends the interior an engagingly dynamic feel while showcasing the typically long doors. The interplay of surfaces and lines in the car's side panels, plus the continuation of the accent strip, creates a visual connection between the front and rear of the interior.The completely new design of the electrically adjustable front seats in the new BMW 4 Series Convertible includes integrated retractable seat belts - a feature not available on any other vehicle in this class. If desired, the standard seats and the sport seats, included with the Sport Line and M Sport, can be equipped with neck warmers for the driver and front passenger as part of the Cold Weather Package in the US. The dynamic character of the 4 Series Convertible can also be seen in the rear compartment. The bench design is contoured to form two individual seats, with cup holders and a storage tray for small items between them. The rear head restraints are separated from the concealed roll bars and can be removed if desired. The roll bars are comprised of two massive steel elements hidden behind the rear seats - in critical situations, sensors trigger the system and the roll bars are extended in less than 200 ms. High-class material combinations, exclusive colors and opportunities for personalization define the premium feel inside the new BMW 4 Series Convertible. As well as the basic trim level, whose material and color concept accentuates the car's classic character; customers have a choice of two BMW Lines as well as the popular M Sport to add individual touches to the car's exterior and interior. The Sport Line and Luxury Line embody different takes on the car's character, adapting the design and color scheme for the kidney grille and air intakes, exterior mirror caps, Air Breathers, trim strips in the front and rear apron, door sill strips and range of wheel rims to set the car apart externally from the basic trim level. The Sport Line adds extra depth to the BMW 4 Series Convertible with a selection of exterior body features in high-gloss black. A sport suspension is included for rear-wheel drive models, setting an exciting tone for the driving experience. The standard high-gloss black B-pillars and black wrap-around window strip give the car an even sportier look, along with nine molded high-gloss black kidney grille slats in a chrome-colored surround. The three black air intakes in the front apron and the likewise black Air Breathers draw the eye to the car's aerodynamic features. 18-inch or optional 19-inch light-alloy wheels (435i only) in twin-spoke design provide a more performance-oriented look. From the rear, the BMW 4 Series Convertible with Sport Line can be identified by the black trim strip level with the rear apron and the black exhaust tips. Inside the car, black and red accents, such as the red trim rings in the inner circle of the instrument dials and red stitching on the sport steering wheel, provide a pronounced contrast. Sports seats are included. The available Coral Red interior includes Coral Red leather sport seats, red door panel trim and a red lower section for the instrument panel. High-gloss chrome touches give the exterior of the BMW 4 Series Convertible a particularly elegant and exclusive appeal. 11 kidney grille slats with chromed fronts and matte black sides, two high-gloss double bridges in the front apron's outer air intakes and chromed Air Breathers all offer elegant touches. The chrome window surround is another visual highlight, with special 18-inch or optional 19-inch light-alloy wheels (435i only) available. The BMW 4 Series Convertible Luxury Line is recognized from the rear by a high-gloss chrome strip in the rear apron and the chrome exhaust tips. The interior also stands out with various chrome elements, such as the surround for the audio and air conditioning system. High-gloss wood strips, leather seats with stitching and a choice of two upholstery variants in four colors highlight the possibilities in the Luxury Line. Exclusively available for the BMW 4 Series, Ash Grain anthracite fine wood trim surfaces and a Pearl Gloss Chrome metal inlay round off the Luxury Line features. Customers wishing to endow their new BMW 4 Series Convertible with as much of the traditional Ultimate Driving Machine character as possible may opt for M Sport. It includes an M aerodynamic package including numerous body components (front apron with large air intakes, rear bumper with diffuser, side skirts) and high-gloss Shadow Line trim. The exterior paint shade Estoril Blue Metallic is available only with M Sport on the 4 Series Convertible. M Sport is further distinguished by 18-inch or optional 19-inch light-alloy wheels (435i only) in M design. Inside, features such as M door sill finishers, an M leather steering wheel and an M driver's footrest complete the atmosphere. Technical features of this package include M Sport suspension (rear-wheel drive models only) and M Sport Brakes (also a stand-alone option on all 435i Convertibles and an optional upgrade on 428i Convertible when M Sport is chosen) which includes calipers painted in blue finish. The new BMW 4 Series Convertible benefits from BMW's customary approach of splitting steering and drive forces between the front and rear axles, which is the ideal platform for balanced driving characteristics, directional stability and agile handling. It also has a 50:50 weight distribution, which sets it apart from its competitors. Taking into account its low center of gravity, unique chassis set-up and lightweight construction, the 4 Series Convertible is an exceptionally dynamic overall package which will satisfy every type of driver. The chassis construction of the new BMW 4 Series Convertible is based on that of the new BMW 4 Series Coupe. However, the springs and damping, axle kinematics and elastokinematics have all been tailored precisely to the character of the new convertible. Indeed, the chassis engineers have managed to make further improvements to the agility and accuracy offered by the chassis, thanks to modification and fine-tuning of variables such as the camber angle, the track and the roll center. Last but not least, special body strengthening elements in the front section and the undercarriage of the car help to further enhance steering precision and feedback. The front suspension of the new BMW 4 Series Convertible combines maximum stiffness with minimum weight. Aluminum torque struts, wishbones and swivel bearings bring a reduction in unsprung weight. At the same time, the engineers optimized the kinematics of the double-pivot suspension for agility and precision. Adjusting the position of the control arms in the swivel bearings from their arrangement on the latest BMW 3 Series Sedan gives the car a .7-inch (19-mm) lower roll center, which has a positive effect on driving performance. An additional strut between the front axle subframe and body sill creates a stiffer overall connection between the front wheels and the car's main structure, so the transverse forces generated on entry into corners are transferred to the car more directly. The BMW 4 Series Convertible responds more directly to the driver's steering commands and displays more sporty characteristics and greater agility. And that means it carves through corners with ease and precision. The rear axle of the new BMW 4 Series Convertible is a key component in its driving characteristics, but that does not mean comfort has been overlooked. This construction is based on the five-link concept, and its elastokinematics have been tuned specially for this sporting convertible. In addition, extra-wide mounts and supports on the wheel carriers for track and camber, slightly repositioned pivot points, stiff control arms and suspension subframes, and the use of thrust arms to connect the suspension with the body all provide an excellent basis for a sporty and dynamic overall set-up. The result is precise and assured wheel location, directional stability in any driving situation. Aerodynamic features around the rear suspension also contribute to driving precision. A standard feature of the new BMW 4 Series Convertible is the Servotronic system which provides speed-sensitive power assistance. The system's precise programming results in sharper steering feel, feedback, precision, accuracy and immediate response. The new BMW 4 Series Convertible can also be equipped with Variable Sport steering as part of the optional Dynamic Handling Package. This provides a somewhat "quicker" on-center steering ratio which then varies depending on the amount of steering "lock" (angle) applied by the driver. The result is even more-lively steering during the "turn-in" phase of cornering, and excellent stability mid-corner and on corner exit. The new BMW 4 Series Convertible comes equipped with powerful swing-caliper or fixed-caliper brakes and large, inner-vented brake discs. The calipers on the front brakes are made of aluminum. As well as low unsprung weight, the brakes also stand out with their high heat tolerance, excellent wet braking performance, ease of use and excellent feel. A brake pad wear indicator and the Brake Drying function are standard on all models. Dynamic performance and handling is significantly influenced by vehicle weight. The new BMW 4 Series Convertible's intelligent lightweight construction concept makes a major contribution to the car's dynamic qualities. The use of high- and ultra-high-strength multi-phase steels and tailored blanks, customized precision components for specific applications, maximizes the body's strength. The torsional rigidity has been increased by 40 percent compared with its predecessor. The top also plays a decisive role in a convertible, because the car does not have a roof serving as a permanent support element. The BMW 4 Series Convertible is up to 44 lbs. (20 kg) lighter than its predecessor, depending on the model, even though the new vehicle is larger and complies with more stringent safety standards. When the hardtop is up, the new BMW 4 Series Convertible highlights its aerodynamic qualities with a Cd (drag coefficient) of 0.28 - which is the same figure as for the new BMW 4 Series Coupe. The convertible achieves a Cd of 0.33 when the top is down. This is possible due to the optimization of the front apron and the rear of the car. The BMW Air Curtains in the front apron generate a veil of air which reduces turbulence - and therefore drag - around the front wheels. The new Air Breathers positioned rearwards of the front wheel arches divert some of the air flowing through the wheel arches, thereby reducing air resistance. These innovations serve to optimize fuel efficiency and - at the same time - enhance the lift coefficient. The M Sport suspension included is part of the Sport Line and M Sport. It works with a firmer spring/shock absorber set-up and stiffer anti-roll bars, and its kinematics/ elastokinematics (bushings and bearings) have also been tweaked to suit the new BMW 4 Series Convertible. The M Sport suspension also includes 18-inch or optional (435i only) 19-inch light-alloy wheels. Alternatively, customers can select a lowered (non-xDrive models) Adaptive suspension, included in the Dynamic Handling Package, which adjusts the electronic damper mapping to each road surface and driving situation. The driver can also use the Driving Experience Control switch to vary the basic suspension settings between comfort and sport, according to personal preference. For performance-minded customers, BMW offers the M Sport Brakes. The aluminum fixed calipers (four-piston at the front, two-piston at the rear) and large discs combine low weight with short stopping distances. The new BMW 4 Series Convertible also offers drivers the ability to change between sporty, eco or comfort settings, depending on mood or preference. Using the Driving Experience Control switch with ECO PRO mode on the center console, drivers can select between ECO PRO, COMFORT, Sport or Sport+ (most models). Each of these selections will activate different settings for the powertrain and suspension components. In Sport mode, throttle response is improved and the steering becomes more direct. If the automatic transmission is fitted, the gearshift points are also altered for sportier driving. Depending on the car's specification, different settings can be selected for the powertrain and chassis components. In Sport+ mode, the Dynamic Stability Control thresholds are raised and Dynamic Traction Control (DTC) is activated. The electronic limited-slip function for the rear differential can then provide better acceleration out of corners or sharp bends. Owning a Convertible reflects a driver's passion for elegant lines and top-down motoring, but it does not rule out performance driving and high-class dynamics. The state-of-the-art powertrain technology under the skin of the new BMW 4 Series Convertible ensures it delivers an engaging driving experience that satisfies even the most demanding expectations. Longitudinally front-mounted, inline engines powering the rear wheels continue BMW's tradition in creating a drive concept that delivers great driving pleasure. Both engines available for the new BMW 4 Series Convertible use BMW TwinPower Turbo technology, which combines sporty performance characteristics with improved efficiency. Available from launch are an inline six-cylinder engine for the BMW 435i Convertible and a four-cylinder unit for the BMW 428i Convertible. These award-winning engines not only supply the BMW 4 Series Convertible with outstanding acceleration and elasticity, they also keep the cars weight down to improve driving dynamics and lower fuel consumption. The new BMW 435i Convertible gives full value to performance-minded drivers thanks to a refined high-revving inline-six engine with instant power delivery and great fuel efficiency. Equipped with High Precision Direct Injection and Valvetronic fully variable valve control, the 3.0-liter engine with aluminum crankcase develops maximum output of 300 hp between 5,800 and 6,000 rpm. Peak torque of 300 lb-ft is generated at 1,200 rpm and remains on tap up to 5,000 rpm. The multi-award winning six-cylinder engine allows the new BMW 435i Convertible to accelerate from 0-60 in about five-and-a-half seconds, on the way to an electronically limited 250 km/h (155 mph) top speed, when equipped with performance tires. << Prev Page 3 of 3 |
