2011 BMW 3-Series Coupe
BMW has announced substantial improvements for 2011 BMW 3-Series Coupe and Convertible, including exceptional style update for the 328i and 335i models and new engine for the 335i model. 2011 BMW 3-Series coupe and convertible models will be sold in spring 2010, and the price will be announced nearer the date of sale.
Basically, do not change their essential attributes of a car rear-wheel drive (xDrive is available in Coupe), almost perfect weight distribution of 50-50, very precise steering and suspension cleverly designed … all conspired to produce a unique driving experience that meets the basic BMW.
Everything new is the engine for the 335i model. Internally designated as the “N55″, this turbocharged, all aluminum engine features essentially the same “short blocks” and the displacement of 3.0 liters of his predecessor, but the added benefit of five years worth of development and improvement. The result is an engine more responsive, more fuel efficient and cleaner-running of his great predecessor, but to protect the engine and soul of the previous output: 300 horsepower and 300 lb-ft of torque, and the 7000 rpm red. The 6-speed manual – is loved by the enthusiast driver of North America – still the norm, and the famous 6-speed STEPTRONIC automatic is optional, it now shows the “gravity” shift paddles on the multifunction steering wheel.
Design. Differences reflect the legendary BMW coupes and convertibles
Profile of BMW 3-Series Coupe and Convertible is directly recognizable at first sight. Beyond the basic shape of the car and the classic lines, the new headlamp design, depth, detail and taillights, interior, exterior mirrors and even created specifically for the coupe and convertible. Unique design elements reflect the character of this sports car. The driver who chooses a two-door car with a vehicle like dynamic behavior and performance. With this in mind, BMW engineers and designers set out to create a single, clear blend of design features and, most importantly, the pleasure of driving.
It all starts with proportion. The new long veil strong symbol of loyalty to BMW’s line-6 engine is inherently balanced. The long wheelbase, short overhangs, the carrier delayed and low, sleek roofline slopes smoothly into the trunk all the features of the BMW coupe and hardtop convertible BMW withdrawal.
In addition to the classic proportions, three design lines of the shoulder, character and line the lower threshold increases clean look. Both the shoulder line and character line stretch interrupted by the rear, which allows a person’s eyes more easily and rapidly from front to rear along the entire length of the car. Threshold under the door trim flows to the front and rear air dams, reinforcing the dynamic nature of the BMW 3-Series coupe and convertible latest.
The combination of lines flowing together highlights the potential performance vehicles elegantly. While the shoulder line rises slightly but always from front to back, flowing lines character long, stretched arch all the way from the front fender of the rear lights of the new. In line with the threshold, however, moves slightly to the rear in a slow and gentle curve, the distance between the characters and the threshold becomes smaller near the lines of the rear wheel arches. Fender flare around each rear wheel also serves to give the character line extra tension in both upward and outward.
Exciting innovations in the front, side and rear – just integrated into the overall look of the car, placing greater emphasis on sportsmanship of the two models. At the same time, expanded slightly modified front and rear overhangs (now 1.14 “and 0.12″ long, respectively), which adds more rational and even the sporting side.
The new, wider front grille, a signature feature of every BMW, the new suit and a broad hood protruding from the surrounding surface. Interactions with three-dimensional kidney frame creates a look of power and unique style. Frame around the grille now have a twisted chrome strip in it.
BMW 3-Series Coupe and convertible come standard in the U.S. with Xenon Adaptive Headlights, accented by BMW’s corona light rings signature. Above, a new lamp is integrated into a cutting bar to cut the power to create a concentrated, focused look typical of BMW. Corona ring, now powered by a source super-bright LED light, can serve as a light in the daytime (if the feature is activated), and the city lights at night, making Convertible and recognized immediately as a BMW, day or night. Top of each lamp is illuminated by the LED light sources.
New light design is one for the BMW 3-Series Coupe and Convertible. Groups backlight function of two L-shaped pieces and highlighted by the new color scheme. With two lines of light tubes at the same time, create the night with a depth of design and dimensions. Integrated color in the body of the car, the lights are divided into two sections and extend into the trunk lid, blending with the character lines from the side profile. LED taillights give the car a horizontal tube is clearly visible at night. The horizontal lines in the Laguna emphasize the wide track and low position of the coupe and convertible.
Additional horizontal contour has been added to the rear air dam and Convertible Coupe wide stress. This creates a light and colors give effect to the entire rear of the flat and smooth appearance.
Exterior Mirror also received a new design, adding more innovation unique view of the BMW 3-Series Coupe and Convertible. Blend harmoniously with the look and shape of each new model.
Deep Sea Blue Metallic, Metallic Vermillion Red, white and colored exterior metallic minerals each will be available for the BMW 3 Series Coupe and Convertible this spring.
Interior: style atmosphere really
The emphasis on individual style, dynamic performance and exclusivity continues within. Again, the focus is on driving experience, as announced by the many standard features leather steering wheel. The horizontal lines dominating the area and around the instrument panel which blend with the lines of the center console, door panels to give the interior a feeling of lightness, but dynamic. The real way to BMW, all operational and information about nutrition is important for driving and grouped around the wheel. Climate control, as well as audio and navigation system, a passenger easily accessible.
Because the coupe and convertible four-passenger vehicles, the rear seat passengers are treated to the center console between the rear seats of each individual, which includes storage boxes, additional sources of air exhaust and lights footrest .
BMW 3-Series Coupe and convertible come standard with Dark Burl Walnut wood trim. As an option, Anthracite Bamboo wood, Light Burl walnut wood, and aluminum is optional. As a rule Dark Burl Walnut, these materials appear in the dashboard, front and rear consoles, doors and rear side panels.
Standard leather upholstery is available in Black and Cream Beige. For the optional leather upholstery, leather can be selected luxury Dakota. Again, the buyer can choose Cream Beige, Oyster, red coral, a chair, brown, gray or Black. Leather seat coverings appeared in the seats, door inserts and door handles surroundings, including other leather trimmed gear shift boot, handbrake and steering wheel.
In other decorative items that do not change with the trim or adjustment options, interior door handles, gearshift surround trim, Radio steering wheel, instrument dial and engine Start / Stop button around, the air dash-adjusting output tabs and the optional iDrive galvanic pearl gray material.
Elegant atmosphere created further inland with special lighting and switches with a premium appearance. Ambient light, streaming from the edge of the door and side panel, and running from one pillar to the rear passenger area, creates a very warm, indirect lighting effects.
Through the design and configuration, with an emphasis in sports cabin and driver-oriented character of BMW 3-Series Coupe and Convertible. Take a seat behind the wheel, the driver’s eyes immediately focus on the instrument panel.
All new turbo engine with Valvetronic for 335i
BMW 3-Series Convertible and Coupe customers have a choice of two engines inline-6 that is the world better. The 328i has 230 horsepower while the 335i has 300 horsepower and is the first line – 6 is equipped with a twin-scroll turbocharger, BMW Valvetronic technology accelerator less consumption, high precision direct fuel injection, and everything is made of aluminum.
The new 335i inline 6-cylinder replaces the 3.0 liter engine developing maximum output of 300 hp at 5800 rpm, with maximum torque of 300 lb-ft is available all the way from 1,200-5,000 rpm. Redline is 7000 rpm. This is the same performance level as the previous 3.0 liters twin-turbo inline-6, but with twice the displacement innovative technology and the integration of Valvetronic, the new engine is more fuel efficient.
Historically, BMW’s engineers are not satisfied with the disadvantages more frequently turbocharger: the frustrating “turbo lag” that occurs between the time the driver hit the accelerator and when the turbocharger develops sufficient rotation to increase power . Turbo-lag is usually worse at low speed. Other shortcomings include fuel consumption is relatively high and poor emissions output. At that time, turbocharger technology was not reliable, practical or efficient was to make power. For this and other reasons, BMW’s turbocharged gasoline engines in the platform to more than 20 years.
Two recent developments are cause BMW to reconsider turbocharging. While many manufacturers of luxury performance car began to get improvements in engine power to create movement, BMW is looking for a more efficient, smaller engines and turbocharging makes sense. Moreover, transfer of technology from BMW turbo diesel engine can be easily transferred to their counterparts in the gasoline. Therefore, BMW articulated a new approach for developing high performance engines as part of its EfficientDynamics initiative.
N55 is the first line of BMW-6 to combine turbocharging, high-precision direct fuel injection and Valvetronic variable intake technology. This unique feature, secondary turbocharged “twin-scroll” housing to improve performance and minimize the response delay. Thanks to the design of adequate housing to maintain separation between the flow of exhaust turbocharger pressure to build faster than the previous generation turbo, thus eliminating even a slight delay of trends.
One advantage of turbocharging is that this is the most difficult of effective methods to improve engine power and performance. The line N55 turbo-6 weighs approximately 150 pounds. cylinder engine unless equally powerful eight-replace to 4.0 liters. This lower weight, a significant advantage, not only fuel economy but also in balancing the weight distribution of the car.
Using Valvetronic, first in line turbocharged-6 allows the engine to “breathe” air for combustion with almost no delay and reduce pumping losses. As a result, the engine makes power more quickly than before, and this is evidenced by the N55′s ability to achieve the maximum torque at 1200 rpm, 200rpm earlier than its predecessor.
As a result, technology in the BMW 335i Coupe and Convertible represent a significant achievement in terms of performance and fuel efficiency. The advantage over a conventional turbocharged engine are not only clearly measurable, but easy to feel on the road.
Turbocharging typically includes cooling the engine air intake, ie compressed air cooling appears very warmed by the compression process, from the turbocharger (s). Sometimes it’s with coolant, in the case of the N55 engine, this is accomplished with outside air. Cooling required to reduce the temperature of incoming air to prevent explosions or “hits” that can reduce power or, in extreme cases, damage the engine. Of course, the N55, like all current BMW engines, is equipped with controlled detonation as part of the digital engine electronics (DME) engine management system. In the N55 engine, DME is now mounted directly to the top of the machine for better packaging and weight savings.
A major burden and pressure cylinder 300-hp N55 engine requires the use of engines with cast-aluminum structure of the iron cylinder sleeves. Overall, the N55 weighs about 427 pounds. The 335i Coupe and Convertible dual exhaust system runs on both sides of the vehicle. Lightly loaded, a channel to cover most of the gas through one side to reduce low frequency exhaust “rumor”. The 335i Coupe and Convertible is air-oil cooler mounted in an external oil the wheels and instead of cooling, the N52-to-oil unit.
Maximum power 300 hp at 5800rpm mentioned, is completely above 70 hp 328i model 2011. At least as important is the fact that the engine can deliver maximum torque from 1200 rpm – not far from idle – 5000 rpm. On the road, power and torque produced an exceptional performance. The 335i Coupe and convertible can accelerate 0-60 mph in just 5.3 (5.5) seconds and 5.5 (5.7) seconds, respectively, when equipped with manual transmission (automatic) transmission. Sense of urgency continues all the way to a top speed electronically limited 130 mph (150 mph when equipped with the optional Sport package). 335i xDrive Coupe accelerates to 0-60 mph in 5.2 (5.3) seconds when equipped with manual transmission (automatic) transmission.
Finally, the new N55 engine can achieve a more favorable signature emissions from its predecessor. Only turbo has only one point and a place of catalytic converter exhaust feeds in the last two machines. This means that the exhaust catalyst is concentrated in the cold start for improved emissions performance, making the N55 is more environmentally friendly engines.
The 328i convertible is driven by horse power of a BMW 230, 200 pounds-feet, 3.0-liter-6 engine, known internally as the N52. Magnesium / aluminum construction Valvetronic variable valve lift are features found only on BMW engines. The N52 made impressive gains in performance and technology in all areas, especially in view of very heavy 357 lbs. Aluminum / magnesium engine block, hollow camshafts, plastic cover of the camshaft, the more improved combustion, was developed camshaft control Double VANOS [1], the fuel injection pressure is greater, electronics sophisticated motor, electric coolant pump, a variable oil pump and oil volume / coolant heat exchanger is the weight-saving features and other improvements of this engine is more than the previous generation.
For Coupes: intelligent xDrive all-wheel available.
2011 BMW 335i Coupe combines intelligent xDrive all-wheel drive with the new powers the BMW 300-horsepower, turbocharged 3.0-liter inline-6 engine. Similarly, the xDrive Coupe 2011 BMW 328i will be impressed with the 230-hp, 3.0-liter-6 shows the construction of the magnesium-aluminum engine. The smooth, dry roads BMW xDrive offers sporty, rear-drive feel. However, in wet or snow-covered road, xDrive automatically send more torque to the axle with better traction. BMW xDrive is the most sophisticated and sensitive system to the wheel traction in the market today. It has proven its services, in terms of agility and safety in the 19 BMW models currently offered with xDrive in the U.S.
For convertibles: Sun-reflective leather seating offers fresh
BMW is the first automaker in the world that uses reflective technology to reduce the temperature of the sun on the leather seats, armrest surfaces, headrests, and shift knob. The process uses modified color pigments imbedded in the skin during the production process, to reflect the sun’s infrared radiation at wavelengths larger than 720 nanometers.
This skin care may reduce the surface temperature in dark colors inside to 20 degrees Celsius (36 degrees Fahrenheit), and also offers advantages in light-colored upholstery, where the sun’s warming effect is less severe, the reduction of surface temperatures to 15 degrees Celsius (27 degrees Fahrenheit). Another quality of the skin was unchanged.
