The Style Rebel
April 22, 2014 – MONTVALE, NJ — Mercedes-Benz is expanding its lineup with the all-new 2014 CLA. The new four-door coupe is a style rebel that takes its design cues from the CLS, whose design concept has inspired more than its fair share of imitators since its debut in Detroit in 2003. This brand new vehicle seamlessly carries the design of the Concept Style Coupe into series production. The all-new 2014 CLA250 arrives in U.S. dealerships this September.
“The response to the Concept Style Coupe was overwhelming. The most frequent comment by far was ‘Please put this car into series production.’ That’s precisely what we are doing now,” notes Dr Dieter Zetsche, Chairman of the Board of Management for Daimler AG and Head of Mercedes-Benz Cars. “The CLA is a car that does not confuse ‘mid-size’ with ‘mid-quality’. Its sporty design underscores the sporty side of the Mercedes-Benz brand.”
The sporty CLA comes with a powerful turbocharged engine generating 208 hp and 258 lb-ft of torque as well as a double-clutch transmission and will be available with 4MATIC all-wheel drive in 2014.
COLLISION PREVENTION ASSIST
This radar-based assistance system provides the driver with visual and acoustic warnings of identified obstacles and primes Brake Assist for adaptive braking. Brake Assist is initiated as soon as the driver steps hard on the brake pedal. When the system identifies a risk of collision, COLLISION PREVENTION ASSIST calculates the precise braking force ideally needed to avoid an accident U.S. Press Information and makes the best possible use of any distance remaining. Adaptive Braking Assist activates at speeds of just 4 mph and gives trailing vehicles as much time as possible to also react accordingly and avoid another accident. COLLISON PREVENTION ASSIST is one of the many standard safety features of the new CLA.
There are five special equipment packages and a series of standalone options for individualizing the striking compact four-door coupe (length/width with mirrors/width without mirrors/height: 182.3/80.0/70./56.6 inches). In keeping with the digital lifestyle of the CLA’s social media-savvy target group, smartphones can also be fully integrated into the vehicle’s display and operating system via mbrace2, which is standard equipment.
Followed by a brief appearance on the eve of the North American International Auto Show in Detroit, the CLA celebrated its official world premiere at the Mercedes-Benz Fashion Week in Berlin (January 15 to 18, 2013). The new CLA will arrive at U.S. dealerships in September 2013.
The style rebel – exterior design
Its sporty proportions and powerfully dynamic design language featuring the interaction of concave and convex surfaces give this four-door coupe its distinctive look. The CLA carries the avant-garde design of the Concept Style Coupe into series production almost 1:1.
Striking features include the hood with its power domes and the diamond-look grille. The arrangement of the headlights and LEDs behind the headlamp lens evokes the characteristic “flame effect” for the optional daytime running lights and indicators. This light signature is a key aspect of the car’s energetic look and shapes a new, youthful Mercedes face.
A number of details indicate that the design of 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 above the fenders flows toward the rear 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 toward the rear. Together, these lines lend depth and dynamism to the side profile.
The design of the rear end emphasizes the width of the CLA, expressing power and athleticism with the interaction of convex and concave surfaces and edges. The gently sloping roof contour and pronounced curve of the rear window retain the CLA’s coupe-style character. The athletic look of the rear end comes from the drawn-in C-pillars paired with the shoulder muscle above the rear wheel arches. The tail lights are framed by the muscular shoulder lines extending into the back while the horizontal light layout emphasizes the car’s powerful and visually striking breadth.
A large panorama sunroof is available as a standalone option. It consists of a fixed polycarbonate cover at the front, a glass moving panel and side trim elements to match the glass look.
Premium look-and-feel – the interior
The exterior’s progressive, sporty appearance also carries through to the vehicle interior. Anthracite surface finish is available as the standard trim. Additional trim options include burl walnut wood, black ash wood and aluminum.
The instrument panel incorporates five air vents. The outer rings of the vents are done in a high-quality galvanized finish, while a galvanized insert controls the direction of airflow. The free-standing display is set in black piano-lacquer trim and edged with a flush-fitting silver frame.
Smart safety – advanced assistance systems
An extensive array of standard and optional driver assistance systems in the CLA is available to the driver. Standard features include ATTENTION ASSIST drowsiness detection and radar-based COLLISION PREVENTION ASSIST with adaptive Brake Assist, which offers collision protection in the CLA from speeds of just 4 mph.
The optional Driver Assistance package also offers DISTRONIC Plus, as well as familiar safety systems including Blind Spot Assist and Lane Keeping Assist. PARKTRONIC with Advance Parking Assist enables autonomous parking in parallel and perpendicular parking spaces and is available as a standalone option.
Precision handling – the chassis and suspension
The CLA’s running gear features McPherson strut suspension at the front and independent multilink suspension at the rear. Three control arms and one trailing arm at each of the rear wheels enable longitudinal and transverse forces to be handled separately. Specific to the CLA is the flexible decoupling of the rear axle sub-frame for improved ride characteristics. The wheel mounts and spring guides are made from aluminum in order to reduce unsprung masses. Standard equipment includes the Mercedes-Benz Sport Suspension for sporty yet comfortable handling.
The CLA also comes as standard with electromechanical power steering. Compared with conventional systems, this power steering system offers improved driver feedback and makes an important contribution to overall efficiency, as the power steering function draws energy only under active steering. It also facilitates various steering assistance functions activated by the ESP® control unit. These include counter-steering in the event of oversteer, corrective steering when braking on road surfaces with differing levels of grip (split-friction braking), minimization of torque steer and compensation for crosswinds and road gradients.
Both the front wheel drive and 4MATIC variants of the CLA250 are delivered on 17-inch, 5-spoke, two-tone wheels clad in all-season, run-flat tires. The Sport Package offers 18-inch AMG twin 5-spoke wheels and adds Sport body styling plus perforated front discs.
High levels of traction and outstanding agility – 4MATIC all-wheel drive
The Mercedes-Benz CLA250 is also available with a new generation of the 4MATIC permanent all -wheel drive system featuring fully variable torque distribution. Like the other 4MATIC variants, this completely new development boasts high levels of traction and outstanding agility combined with excellent safety and energy efficiency.
The components of the new 4MATIC include the power take-off to the rear axle, which is integrated into the 7-speed Dual Clutch Transmission, and the rear-axle gear set with an integrated electro-hydraulic, multi-disc clutch. This set-up enables fully variable distribution of drive between the front and rear axles. Additional benefits of this design are a lower system weight than that of competitor systems, as well as a high degree of efficiency.
All set for the future – a powerful and efficient drive
The CLA250 and CLA250 4MATIC both feature Mercedes-Benz’s 2.0-liter four-cylinder gasoline engine with 208 hp and 258 lb-ft of torque. It comes with the ECO stop/start function as standard for added gas mileage and is mated to the 7-speed Dual Clutch Transmission for an outstanding combination of sporty performance and comfort.

ALL-NEW 2014 MERCEDES-BENZ CLA45 AMG: ‘DRIVING PERFORMANCE’ AT ITS BEST
Mercedes-Benz AMG celebrated its world debut of the 2014 model year CLA45 AMG at the New York International Auto Show. Set to go on sale in the U.S. this November, the four-door coupe follows in the design footsteps of the successful CLS63 AMG, the trendsetter for four-door highperformance coupes. With 355 horsepower and torque of 332 lb.-ft., the 2014 CLA45 AMG is the world’s most powerful four-cylinder production engine. The AMG Performance 4MATIC all-wheel drive system on the CLA45 AMG sets new standards in its segment as well.
Ola Källenius, outgoing CEO of Mercedes-AMG GmbH: “In the CLA45 AMG, Mercedes-AMG presents a unique and absolutely desirable automobile with the characteristic AMG genes. The high-tech package with the world’s most powerful four-cylinder production engine and performance-oriented AMG 4MATIC all-wheel drive stands for ‘Driving Performance’ at its best.”
Pure AMG: the most powerful four-cylinder production engine in the world
The 2014 CLA45 AMG two-liter turbo engine is the most powerful turbocharged four-cylinder production engine with 355 hp and 332 lb.-ft. of torque. The combination of high power, strong torque and performance-oriented all-wheel drive lends the CLA45 AMG superb driving performance. The powerful coupe sprints from 0-60 in 4.5 seconds, and top speed is electronically limited to 155 mph. Mercedes-AMG achieves these impressive figures by the use of high-tech engineering throughout the engine and related systems. The combination of multiple injection and multiple spark ignition on each piston stroke improves fuel atomization and substantially increases thermodynamic efficiency, contributing to low exhaust emissions. Other highlights include a sand-cast aluminum crankcase, weight-optimized crank assembly with forged steel crankshaft and forged pistons with friction-optimized piston rings, NANOSLIDE cylinder lining technology, water-to-air intercooling, alternator management and ECO Start/Stop function.
Twin-scroll turbochargers and AMG sports exhaust system with butterfly valve
Mercedes-AMG addresses the challenge of small-displacement turbo engines by using a twin-scroll turbocharger, minimized restrictions in the exhaust system and an innovative injection strategy. Twin-scroll technology makes effective use of exhaust gas back pressure, temperature and momentum to provide a faster buildup of boost pressure, for a quicker build-up of torque from low revs. Twin scroll technology also benefits gas mileage and exhaust emissions. With boost pressure of 11.9 psi (0.8 bar), the AMG 2.0-liter four-cylinder turbo engine also leads the field with the highest boost pressure used in a production engine.
The AMG Sports Exhaust system features large pipes and an automatically controlled butterfly valve in the exhaust system. This technology (also used in the SLK55 AMG) allows the CLA45 AMG to deliver a distinctive sound on acceleration while also offering a refined note at sustained speed, such as during highway cruising. The valve is continuously adjusted by the engine computer, based on signals about gas pedal position and engine speed.
The exhaust butterfly valve provides a more striking exhaust note when the throttle is open and during shifts. It also produces an especially strong sound during downshifts using the rev-matching feature as well as during upshifts under full load with the momentary suppression of ignition and injection. And, the AMG Performance Exhaust system creates an enhanced exhaust note that is typically reserved for engines with more than four cylinders.
High-performance cooling system with components from the SLS AMG GT
The high power of the CLA45 AMG calls for a highly effective cooling system. Similar to technology in the SLS AMG GT, an extra low-temperature cooling circuit is installed for water-to-air intercooling of the pressurized intake air. A large radiator at the very front of the cooling module is supplemented by a second
radiator in the wheel well. A high-performance electric pump provides high flow through the water radiators behind the large air intakes and the intercooler. This provides ideal cooling of the highly compressed intake air, contributing to optimum engine performance.
Cooling of transmission oil is integrated into the engine water cooling circuit. The
radiator behind the front fascia is supported by another heat exchanger, which is
fitted directly on the transmission and supplied with cooling water by an auxiliary
“One man, one engine”: engine production the traditional artisan way
Like all AMG V8 and V12 engines, the new 2.0-liter four-cylinder turbo engine is hand-built according to the traditional AMG philosophy of “one man, one engine” on an exclusive assembly line for the new AMG engine at the Mercedes-Benz engine production plant in Kölleda, Germany. The “one man, one engine” production process is evident in the AMG engine plate bearing the personal signature of the engine builder. The engine plate serves as a symbol of AMG’s superlative production quality and underscores the peerless genes of the Mercedes-Benz high-performance brand.
AMG SPEEDSHIFT DCT 7-Speed sports transmission
Dual-clutch transmission and all-wheel drive – the drive train on board the CLA45 AMG is a dramatic demonstration of engineering prowess. The AMG SPEEDSHIFT DCT 7-Speed sports transmission is mounted directly to the transversely installed AMG 2.0-liter four-cylinder turbo engine. The dual clutch transmission of the CLA45 AMG features seven gears, three driving programs, a rev-matching function and RACE START for optimum acceleration. The highlights of the AMG DCT sports transmission include fast shifts without interrupting power, a tailormade control strategy, extremely smooth and easy gearshifts and a high level of efficiency. Reinforced gears ensure maximum durability, and synchronizer rings with carbon-fiber friction linings improve longevity while also optimizing response during manual gearshifts – the ideal situation for ambitious lap times on a closed circuit.
“Momentary M mode” for even greater dynamics and driving pleasure
Another special feature designed to enhance performance and driving pleasure is the “Momentary M” program. In the C and S shift modes, the driver can activate the “M” manual mode without having to remove a hand from the steering wheel, by simply pressing the “up” or “down” shift paddle once. In “Momentary M” mode, the driver experiences the dynamics and performance in all automatic driving programs, with automatic upshifts only at the rev limit. This allows drivers to devote their full attention to the vehicle’s impressive performance.
The shift times in manual mode “M” and in sport mode “S” are similar to the SLS AMG GT super sports car. Momentary suppression of ignition and injection under full load leads to even faster gearshifts with a more exciting sound than ever. In “C” mode (Controlled Efficiency), soft transmission and engine characteristics are conducive to a fuel-efficient and comfort-oriented driving style. In addition, the ECO Start/Stop function is active in “C” mode.
AMG Performance 4MATIC all-wheel drive
The development focus for the standard AMG Performance 4MATIC all-wheel drive was on “performance” and “dynamic spirit.” A compact power take-off unit (PTU) that’s fully integrated into the 7-speed sports transmission transfers power to the rear wheels. Its lubrication is supplied by the same oil circuit as the transmission, resulting in substantial weight advantages compared with rival systems, which use an add-on PTU with a dedicated circuit. Together with low-friction tapered roller bearings, the PTU delivers excellent efficiency. As an additional bonus, the weight of the new AMG 4MATIC all-wheel drive is up to 25 percent less than the systems offered by competitors.
A two-part propeller shaft transfers engine power to the rear wheels. Contributing to favorable weight distribution, a multi-disc clutch is integrated into the rear differential. An electronically controlled hydraulic pump instantaneously presses the discs together and channels engine torque dynamically to the rear wheels when needed. All this takes place virtually unnoticed by the driver. For fast response, the pump is always active and doesn’t need to be started each time it’s needed (as is usually the case with other systems). The torque split is fully variable: in normal driving, the CLA45 AMG is front-wheel drive for optimal efficiency. If the system senses any front wheel slippage, the variable AMG 4MATIC all-wheel drive distributes torque between front and rear wheels at a ratio of up to 50 : 50. The variables influencing the torque split are speed differences between individual wheels, vehicle speed, lateral and longitudinal acceleration, steering angle, selected gear and accelerator position.
3-stage ESP® with ESP® Curve Dynamic Assist
An exclusive feature of the CLA45 AMG is the interaction of the 4MATIC all wheel drive with the 3-stage ESP® and ESP® Curve Dynamic Assist. The three ESP® stages enable drivers to vary the dynamics of the CLA45 AMG according to their individual preferences at the push of a button. The normal “ESP ON” mode helps the driver maintain safe and neutral handling. The system initiates braking on one or more wheels to neutralize the onset of unstable driving conditions.
Briefly pressing the ESP® button activates a “SPORT Handling” mode, which delays ESP® intervention and allows more torque at the rear wheels. This means more driving fun for those who enjoy using the car’s full handling potential. Pressing and holding the ESP® button activates the “ESP OFF” mode, which should only be used by experienced drivers on closed circuits. Whenever a driver steps on the brake pedal in “SPORT Handling” or “ESP OFF” mode, all safety features of the ESP® system are available for the duration of the braking.
ESP® Curve Dynamic Assist complements the ESP® system: during spirited cornering, imperceptible braking on an inside wheel directs more torque to the outside wheel, resulting in precise and safe turn-in of the CLA45 AMG. ESP® Curve Dynamic Assist is different in each ESP® mode, and in “SPORT Handling” and “ESP OFF,” it helps fulfill the driver’s wish for increased agility and driving dynamics. ESP® Curve Dynamic Assist is an extra feature of the already impressive Electronic Stability Program, which noticeably improves not only agility, but also active driving safety, at least within the limits of the laws of physics.
AMG sports suspension with multi-link front and rear axles
Like every high-performance AMG automobile, the CLA45 AMG also incorporates sophisticated suspension technology. For enhanced driving dynamics, its threelink front suspension has stiffer steering knuckles and totally new elastokinematics. Newly developed, more rigid bearings are used in the lower link plane to ensure more agile turn-in as well as more precise and direct feedback from the road. More rigid bearings also lead to better camber stability, allowing higher cornering speeds. In developing the complete front suspension, great importance was placed on maintaining the best possible traction under very sporty driving conditions.
The CLA45 AMG four-link rear suspension is also a totally new development. To optimize elastokinematics, the bushings were modified for maximum driving dynamics and control. The rear suspension carrier is fitted with more rigid bearings for increased directional stability, and the subframe is rigidly bolted to the body. With its tuned spring / shock absorber units and larger stabilizer bars, the AMG sports suspension ensures high lateral acceleration and a reduced body roll in fast S-bends. The CLA45 AMG comes standard with twin-spoke AMG lightalloy wheels inlayed in titanium gray with a high-sheen finish and fitted with 235 / 40 R 18 tires.
AMG speed-sensitive sports steering and AMG high-performance braking system
The electromechanical sports steering with AMG speed-dependent power assist and a constant steering ratio of 15.1:1 provides precise and agile steering. Its electric motor is installed directly on the steering gear to save space.
To provide quick, reliable deceleration, AMG high-performance brakes feature vented and perforated front and rear discs that measure 3.8 x 1.2 inches at the front and 13.0 x 0.8 inches at the rear.
Even at first glance, the new CLA45 AMG leaves no doubt about its character; similarities with the CLS63 AMG are intentional. Mercedes-AMG complements the expressive design idiom with distinctive AMG elements, creating a new design standard. The CLA was developed with sporty proportions – the AMG “twin blade” radiator grille and the cross member in the AMG front fascia, both painted matte titanium gray, further reinforce its sporty appearance. Large air inlet ports on the sides are framed by black winglets that improve air flow to the cooling system behind them. Bi-xenon headlights are part of the standard equipment.
From the side of the CLA45 AMG, sill panels with matte titanium gray inserts catch the eye. Other elements of a top-of-the-line AMG model are the twin-spoke AMG light-alloy wheels, inlayed in titanium gray with a high-sheen finish, as well as a “TURBO AMG” badge on the fender. The AMG rear fascia includes stylized side air vents as well as a large diffuser insert and matte titanium gray trim. The conjoined quad-tip chrome tailpipes of the AMG exhaust system emphasize its sporty purpose. Striking LED tail lights come as standard equipment.
Dynamic, exclusive and high-quality interior
Obvious quality, high-end materials and a sporty, exclusive character typical of Mercedes-AMG make the interior of the CLA45 AMG impressive. Standard equipment includes AMG door sill panels, sport seats wrapped in MB-Tex manmade leather and DINAMICA microfibers with red contrasting stitching, red seat belts, a multifunction steering wheel with shift paddles and an AMG DRIVE UNIT bearing the AMG Affalterbach Crest. The AMG instrument cluster provides key information with a central color display, the AMG main menu and the RACETIMER, while brushed aluminum trim on the instrument panel is matched to the five anodized ventilation nozzles.
