Sleek as they come: The Style Rebel – Mercedes-Benz CLA

Sleek as they come: The Style Rebel – Mercedes-Benz CLA

The CLA has established a new segment as a new four-door coupé that follows the idea of the CLS, whose design concept has spawned more than its fair share of imitators since its debut in 2003. With its frameless doors, the coupé adopts the design of the Concept Style Coupé into series production.

"The CLA is a car that has standard features usually found in the luxury premium segment and affirms that for Mercedes-Benz, safety is not a question of price,” says Florian Seidler, Vice President, Sales & Marketing for Passenger Cars, Mercedes-Benz South Africa.

“With world-leading aerodynamics (Cd = 0.22), avant-garde coupé design, its design underscores the sporty side of the Mercedes-Benz brand," adds Seidler.

In keeping with its sporty positioning, the CLA is available with high-torque turbo engines rated at up to 125 kW and sports suspension for the Urban and AMG Sport Line. The technical highlights of this new design icon include a new world record in aerodynamics for series production automobiles (Cd value: 0.22). Numerous driving assistance systems, including advanced COLLISION PREVENTION ASSIST are standard. This system is able to warn the driver of an obstacle from a speed of 7 km/h and to initiate precision braking when the driver steps on the brake pedal.

This radar-based assistance system provides the possibly distracted driver with visual and acoustic warnings of identified obstacles and prepares Brake Assist for precision braking. Braking is initiated as soon as the driver steps emphatically on the brake pedal. When an impending danger of collision is identified, COLLISION PREVENTION ASSIST calculates the precise braking force ideally needed to avoid an accident and makes the best possible use of any distance remaining. As a new feature, COLLISION PREVENTION ASSIST affords protection from typical rear-end collisions in dangerous traffic situations in the CLA from a speed of only 7 km/h (previously: over 30 km/h).

The style rebel: exterior design

Its breathtakingly sporty proportions and powerfully dynamic design idiom featuring an interplay between concave and convex surfaces give this four-door coupé its unmistakable look. The CLA adopts the avant-garde design of the Concept Style Coupé into series production almost 1:1.

The vehicle's striking features include the bonnet embedded in the front end with power domes and the diamond radiator grille. The light modules and LEDs behind the headlamp cover glass have been arranged in such a way as to create the characteristic "flare effect" for the daytime driving lights and indicators. This light signet defines the car's energetic appearance and shapes a new, youthful Mercedes face.

Numerous details indicate that on a design level the CLA represents a further development of the modern classic Mercedes-Benz CLS. Three prominent lines give structure to the vehicle when viewed from the side: the front structural edge over the wings flows towards the rear end in a characteristic dropping line. Another, more sinewy line spans the shoulder muscle above the rear axle, while the third feature line extends in a sweeping curve from the front wheel towards the rear. Together, these lines lend depth and dynamism to the side profile.

The width-emphasizing rear end exudes power and athleticism, featuring an inter-play between convex and concave surfaces and edges. The gently sloping roof contour and the pronounced, hallmark curvature of the rear window provides the CLA with a coupé-style character from the rear, too. The athletic impression from the rear results from the drawn-in C-pillars in conjunction with the shoulder muscle over the rear wheel arch linings. The tail lights are framed by the muscular lines of the shoulders which extend into the rear end, the horizontal orientation of the lights emphasizing the rear's powerful and aesthetic breadth. The light functions feature an arrow-style arrangement.

"Cool touch" effect: the interior

The exterior's progressive, sporty appearance is continued inside the vehicle. The interior additionally derives a very special quality feel from the design idiom, the selection of high-quality materials and the available combinations of materials. All trim surfaces are galvanised, resulting in a metallic finish.

The instrument panel incorporates five round vents. The outer rings of the round vents have a high-quality electroplated finish. The airflow direction is governed by a galvanised insert that reveals a meticulous attention to detail. The free-standing display screen features a black piano-lacquer-look front panel and a flush-fitting silver frame.

The CLA is fitted with integral seats in the front and rear, underscoring its sporty character. The rear bench seat emphasizes the outer seats (2+1-seater). Coloured contrasting stitching is available, according to the selected interior appointment options. A fibre-optic cable in the opening between head restraint and backrest is optionally available as part of the ambient lighting.

Sleek as they come: new record Cd value

With a Cd value of 0.23, the CLA sets a new benchmark – both within the Mercedes-Benz model range and among all production vehicles. The drag area, Cd x A – which is crucial to aerodynamic resistance – also leads the field, at 0.51 m². This already record figure is undercut still further by the CLA 180 BlueEFFICIENCY Edition (not available for SA).In this case the Cd figure is 0.22, while in terms of wind resistance the four-door coupé manages to breach another magic barrier: the figure here is just 0.49 m².

The good air flow characteristics, which are a major contributory factor to the vehicle's low fuel consumption in everyday conditions, result from numerous aerodynamic optimisation measures. These include a low A-pillar shoulder with adapted A-pillar geometry, aerodynamically optimised exterior mirrors, wheel trims designed for low aerodynamic drag and serrated wheel spoilers on the front and rear wheel arches.

Extensive underbody panelling, additional panelling in the middle area of the rear axle and an aerodynamically optimised rear silencer followed by a diffuser improve the flow of air under the underbody.

Smart safety: advanced assistance systems

Numerous driving assistance systems offer support in the CLA and reduce the driver's workload. Standard-fit features for the coupé include ATTENTION ASSIST drowsiness detection and radar-based COLLISION PREVENTION ASSIST with adaptive Brake Assist, which now helps to protect the CLA from collisions from a speed of only 7 km/h (previously: over 30 km/h).

This feature combines with DISTRONIC PLUS to become COLLISION PREVENTION ASSIST PLUS, incorporating an additional function: when a danger of collision persists and the driver fails to respond, the system is able to carry out autonomous braking at speeds of up to 200 km/h, thereby reducing the severity of collisions with slow or stationary vehicles. The system also brakes in response to stationary vehicles at a speed of up to 30 km/h and is able to prevent rear-end collisions at speeds of up to 20 km/h.

Established assistance systems, such as the Lane Tracking package with Blind Spot and Lane Keeping Assist or Adaptive Highbeam Assist, are also available for the CLA. Active Parking Assist (option) enables automatic parking in lengthways and crossways parking spaces.

Designed for dynamism: the chassis and suspension

The chassis of the CLA features a McPherson front axle and an independent multilink rear suspension, featuring three control arms and one trailing arm per wheel. This means that longitudinal and lateral dynamics are virtually independent of one another. A CLA-specific feature is the flexible decoupling of the rear axle carrier, which benefits ride comfort. Wheel carriers and spring links consist of aluminium, in order to reduce the unsprung masses. Two chassis and suspension set-ups are available: the comfort suspension and the optional sports suspension for sporty yet comfortable handling. The latter entails lowering of the body by 20 mm (front) and 15 mm (rear).

Irrespective of the selected chassis, all CLA variants come with the Direct Steer system. This electromechanical power steering offers improved feedback to the driver in comparison to conventional systems regarding the prevailing driving conditions and makes an important contribution towards overall efficiency, as the steering assist function only requires energy when steering is actually carried out. It additionally enables various steering assistance functions which are activated by the ESP® control unit. These include countersteering in case of oversteering, corrective steering when braking on road surfaces offering different levels of grip (split-friction braking), mitigation of the extent to which the front-wheel drive influences the steering and compensation of crosswind and road gradients.

All set for the future: powerful and efficient drive

A year ahead of the scheduled introduction of the Euro 6 in 2014, all petrol-engine variants and the top diesel variant of the new Mercedes-Benz CLA already meet the future requirements of this European emissions standard.

The petrol engines with a displacement of 1.6 and 2.0 litres cover an output spectrum ranging from 90 kW in the CLA 180 through to 115 kW in the CLA 200. The 2.2-litre diesel engine combines dynamic low-end torque with the utmost efficiency: the CLA 220 CDI generates 125 kW, with maximum torque of 350 Nm, emitting only 109 g CO2 per kilometre.

All the engines feature the ECO start/stop function as standard. The CLA 180 and CLA 200 engines are combined with a six-speed manual transmission or optional with the 7G-DCT dual clutch automatic transmission. The CLA 220 CDI comes standard with the 7G-DCT automatic transmission, which reconciles comfort and sportiness in inimitable fashion.

The model range: sporty and exclusive

With the "Urban" and "AMG Line" equipment lines, three design packages and numerous other optional extras, the CLA can be personalised to suit every taste. The CLA Edition 1 will only be available for twelve months. Among the exclusive equipment features of this model, which can be powered by any of the engine versions, the NEON ART interior with leather upholstery and black DINAMICA microfibre with yellow contrasting topstitching is worthy of mention.

With air conditioning, 3-spoke multifunction steering wheel with 12 function buttons, steering column adjustable in height and longitudinal direction, green-tinted heat-insulating glass, Audio 20 CD radio with dual tuner, colour display and MP3- WMA- AAC-capable CD drive, six speakers as well as Aux-in socket and USB interface in the centre armrest for external audio and video devices, even the standard equipment of the new CLA-Class is particularly generous. A colour display between the two large dials in the instrument cluster is likewise standard ex-factory for the CLA.

In addition, numerous driving assistance systems offer support for the driver. Standard-fit features for the coupé include ATTENTION ASSIST drowsiness detection and radar-based COLLISION PREVENTION ASSIST with adaptive Brake Assist, which now helps to protect the CLA from collisions from a speed of only 7 km/h (previously: over 30 km/h).

With the equipment lines "Urban" and "AMG Line", three design packages and optional extras, it is possible to individualise the coupé further.

Two types of character: the equipment lines

The "Urban" equipment line can be combined with all the engine variants, except the CLA 180 BlueEFFICIENCY Edition. Its dynamic impression comes courtesy of the sports seats with their upholstery in ARTICO man-made leather/Corumba fabric. Seats, armrests, multifunction steering wheel and gearshift lever are in nappa leather. The 3-spoke leather steering wheel features perforations in the grip area. The seating comfort package, the multifunction switch on the centre console and the 12-V power outlet in the vehicle rear are all part of the standard equipment scope. Trim elements in silver wave-look (alternatively anthracite wave-look), with matching air outlet vents with nozzle ring and cross in silver chrome. Characteristic exterior features are the diamond radiator grille (with black pins, silver-coloured louvre and insert in silver chrome) as well as the twin-pipe exhaust system with rectangular-section tailpipe trim in polished stainless steel. A sports suspension with lowered vehicle body are standard features, however, a comfort suspension is also optionally available. The "Urban" design and equipment line rolls on 5-spoke 18-inch himalaya-grey light-alloy wheels.

"AMG Line" is the name of the second equipment line, available for all the versions of the vehicle with the exception of the CLA 180 BlueEFFICIENCY Edition. Here the emphasis is on the colour red: in the contrasting topstitching on the sports seats (upholstered in ARTICO man-made leather/DINAMICA microfibre), the multifunction sports steering wheel in nappa leather with flattened lower section, and the armrests. Matching these appointments, the stainless steel sports pedals with rubber studs. This line features trim elements in light-tone longitudinal-grain aluminium. And the exterior is quite as sporty, too: the "AMG Line" features a twin-pipe exhaust system with rectangular-section tailpipes in polished stainless steel, a diamond-pattern radiator grille with silver pins, 5-twin-spoke AMG 18-inch titanium-grey high-sheen light-alloy wheels, AMG bodystyling (front and rear aprons, side sill panels). If the customer chooses the "AMG Line", he or she will also receive a CLA-Class with sports suspension and lowered vehicle body, perforated front brake discs and front brake callipers with "Mercedes-Benz" lettering.

Tailored-to-measure upgrades: the design packages

Three design packages, "Exclusive", "AMG Exclusive" and "Night package" offer further individualisation possibilities. The "Exclusive" package which can be chosen in addition to one of the two design and equipment lines, with its extremely select, high-level interpretation of this vehicle segment does all honour to its name, with sports seats upholstered in leather, dashboard and door centre panels in ARTICO man-made leather and trim elements in trapezium-grain aluminium. The beltlines are also in ARTICO man-made leather. A 3-spoke leather-clad steering wheel with 12 function buttons is standard equipment, as is the 4-way adjustable lumbar support for the front seats and the seat heating. The locking system includes an infra-red receiver in the driver's door as well as the convenience closing system that allows the side windows and the panoramic sliding sunroof to be comfortably opened and closed using the car key.
