Η Mercedes-Benz παρουσίασε και επίσημα την GLA στην έκθεση της Φρανκφούρτης. Η GLA αποτελεί την έκδοση παραγωγής του GLA Concept που είδαμε στην έκθεση της Σανγκάη τον Απρίλιο και στην ουσία είναι η crossover έκδοση της A-Class.
Μετράει 4,41 μέτρα σε μήκος, 1,80 μέτρα σε πλάτος και 1,49 μέτρα σε ύψος, όντας συνολικά μεγαλύτερη από την A-Class διατηρώντας ωστόσο το μεταξόνιο της. Εξωτερικά, διαθέτει ένα εξαιρετικά μυώδες και επιθετικό bodykit που πλαισιώνεται από αεροτομή, μεγάλες ζάντες, ράγες οροφής και διπλές απολήξεις της εξάτμισης στο πίσω μέρος. Ο αεροδυναμικός συντελεστής οπισθέλκουσας διατηρείται στο εξαιρετικό για την κατηγορία και όχι μόνο, 0,29Cd ενώ στο εσωτερικό, μπορούν να φιλοξενηθούν άνετα τέσσερις ενήλικες με τις αποσκευές τους αφού ο χώρος αποσκευών ξεκινάει από τα 421 λίτρα και φτάνει τα 836 λίτρα με την αναδίπλωση των πίσω καθισμάτων –βέβαια αν τα αναδιπλώσετε να δω που θα καθίσουν οι 4 επιβάτες αλλά τέλος πάντων-. Όσον αφορά στον εσωτερικό διάκοσμο, αυτός είναι πρακτικά ίδιος με ότι έχουμε δει στην A-Class με μερικές διαφοροποιήσεις στα επίπεδα εξοπλισμού μεταξύ των δύο μοντέλων.
Μηχανικά θα φορά την ίδια γκάμα κινητήρων βενζίνης και πετρελαίου που φορά η νέα A-Class. Έτσι αρχικά θα είναι διαθέσιμες οι εκδόσεις GLA 200 με τον 1.600αρη turbo κινητήρα απόδοσης 156 ίππων, GLA 250 και με τον 2,0-λιτρο turbo κινητήρα απόδοσης 211 ίππων και μέση κατανάλωση 7,1 λίτρα/100 χλμ, GLA 200 CDI με τον 2,2-λίτρων turbodiesel απόδοσης 136 ίππων και 300 Nm ροπής με μέση κατανάλωση 4,3 λίτρων/100 χλμ και η έκδοση GLA 220 CDI με τον 2,2-λίτρων απόδοσης 170 ίππων και 350 Nm ροπής. Οι κινητήρες συνδυάζονται με μηχανικά και αυτόματα κιβώτια, τα οποία στέλνουν την κίνηση είτε στους μπροστά είτε και στους τέσσερις τροχούς.
Η GLA 250 είναι μόνο τετρακίνητη και τα 0-100 χλμ/ώρα τα κάνει σε 6,5 δεύτερα, έχοντας τελική ταχύτητα 233 χλμ/ώρα. Η τετρακίνηση επίσης είναι διαθέσιμη στην GLA 220 CDI, με το σύστημα τετρακίνησης να διαθέτει το σύστημα Downhill Speed Regulation (DSR) και off-road λειτουργία του κιβωτίου.
Αργότερα θα υπάρχει και AMG έκδοση, η οποία θα φορά τον 2,0-λιτρο turbo τετρακύλινδρο κινητήρα των A45 AMG και CLA 45 AMG, απόδοσης 360 ίππων με 450 Nm ροπής. Στιλιστικά εκτός από την αυξημένη απόσταση από το έδαφος θα διαθέτει μεγαλύτερη γρίλια, αεροτομή, νέα πίσω φωτιστικά σώματα και ράγες στην οροφή.
Αργότερα ίσως προστεθεί στη γκάμα και η έκδοση GLA 170 CDI με τον 1.500αρη turbodiesel κινητήρα απόδοσης 109 ίππων. Η κατασκευή της θα γίνεται στο εργοστάσιο της Mercedes-Benz στο Kecskemet της Ουγγαρίας, εκεί όπου κατασκευάζεται η B-Class και η CLA. Οι πωλήσεις θα ξεκινήσουν από τον Νοέμβριο με τις πρώτες παραδώσεις να γίνονται από τις αρχές του 2014.
Οι πρώτες παραδόσεις της Mercedes-Benz GLA θα ξεκινήσουν στις αρχές του επόμενου έτους ενώ τότε περίπου περιμένουμε από την Mercedes να αποκαλύψει και την GLA AMG.

Fit for off-road excursions
Multi-talented: The new Mercedes-Benz GLA
Stuttgart. Progressive in design, serene in day-to-day motoring and with an off-road capability: as a wanderer between automotive applications, the Mercedes-Benz GLA impressively reinterprets the compact SUV segment. It lightfootedly masters all day-to-day challenges and is also robust enough for off-road excursions.
The first Mercedes-Benz in the fast-growing compact SUV segment is highly manoeuvrable around town (length x width x height 4417 x 1804 x 1494 millimetres), lively on country and pass roads and dynamic and efficient on the motorway (Cd figure 0.29). The high-quality appointments, developed with much love for detail, and the flexible interior clearly position the GLA as a compact premium SUV.
The GLA is the first Mercedes-Benz SUV to be optionally available with the new-generation permanent all-wheel drive system 4MATIC, with fully variable torque distribution.
The new GLA rounds off the extensive SUV portfolio of Mercedes-Benz. With five model series (GLA, GLK, ML, GL and G) the company offers the widest range of any European premium manufacturer, and meets all the individual mobility wishes of its customers. At the same time the GLA-Class is the fourth of a total of five new compact models from Mercedes-Benz. The sales figures amply demonstrate how well the new compact models are received by customers: In the first half of 2013, for example, 173,362 units of the A and B‑Class and the new CLA Coupé were delivered worldwide (+58.0%). Especially gratifying is the high conquest rate of the new A-Class: around 50 percent of the buyers in Europe come from other brands.
“With the compact GLA we add a fifth attractive SUV variant to the Mercedes‑Benz model portfolio in this constantly growing segment. The GLA impresses mainly with its progressive character and agile handling,” says Dr Joachim Schmidt, Executive Vice President Sales and Marketing Mercedes‑Benz Cars. “So I am very confident that the GLA with its fascinating design and high everyday practicality will fill many new customers with enthusiasm for the Mercedes-Benz brand.”
As a serene day-to-day companion the GLA has a flexible and variable interior. The rear seat backrests can not only be folded down completely, but are also adjustable for angle if required. The generous luggage compartment (421 – 836 litres) is well-presented and can be loaded without difficulty thanks to the low loading sill and the wide tailgate, which opens automatically as an option.
The particularly rigid body structure provides a reliable basis for a wide range of applications. Initially the power range of the 1.6 and 2.0-litre petrol engines will extend from 115 kW (156 hp) in the GLA 200 to 155 kW (211 hp) in the GLA 250.
The two diesel engines excel with dynamic torque and outstanding efficiency: The GLA 200 CDI develops 100 kW (136 hp) and maximum torque of 300 Nm and has a displacement of 2.2 litres. It emits only 114 g CO2 per kilometre (provisional figure). The GLA 220 CDI likewise has a displacement of 2.2 litres and develops 125 kW (170 hp) and 350 Nm.
The GLA will celebrate its world premiere at the International Motor Show (IAA) in Frankfurt (12 to 22 September 2013). Orders will be taken from the end of November, and the GLA will be in dealer showrooms in 2014.
Design: quality and self-assurance
Sensual clarity as an expression of modern luxury – this was the focus for the designers, and is the design philosophy of Mercedes-Benz. The aim is to create clear contours and smooth surfaces that communicate high-tech while exuding emotional appeal as a meta-level. The sensual clarity is reflected in the core design values of Tradition, Emotion and Progression. These are the guiding star, and are accentuated differently depending on the model. Mercedes-Benz creates a bridge between modernity and the avant-garde, between tradition and progression. Each model series has an assigned role and has a very specific character, depending on the attributes on which the design focusses. And yet a Mercedes-Benz is always recognisable as a Mercedes-Benz. Because in addition to incorporating new stylistic developments, and in the interests of keeping tradition alive, the designers draw from a gene-pool of styling features typical of the brand.
“With its striking features the GLA embodies our progressive thinking and enthrals with its off-road proportions,” says Gorden Wagener, Vice President Design at Daimler AG. “The clearly defined surfaces convey power and serenity, and we have managed to combine as much emotional appeal as possible with as much clarity as necessary.”
As an SUV, the new GLA combines the design values of Progression and Tradition, and is the SUV of the future. It is an all-rounder with hallmark Mercedes-Benz SUV genes, but more youthful, sculptural and full of subtle drama.
The low greenhouse, raised vehicle body and large wheel arches give the GLA great appeal. The clearly defined surfaces are supplemented with sharp lines that provide definition and precision, varying the sculptured contours of the vehicle body which is sensitively modelled and subtly dramatic.
The prominent and self-assured, upright front end with a central star lends a muscular and superior impression to the GLA. Powerdomes structure the bonnet as sporty features, and the twin-louvre grille accentuates the vehicle’s width. An impressive front aspect is ensured by the headlamps and LED daytime running lamps. This iconic Mercedes-Benz design feature was developed further using trifunctional fibre-optics, and gives the vehicle its characteristic light signature. The front bumper features diamond-pattern grilles in front of the cooling air intakes. The optional fog lamps are integrated into the front bumper. A simulated underride guard and contrasting dark-grey claddings all-round emphasise the SUV characteristics of the GLA. These claddings begin low down at the front bumper and provide protection against stone impact.
The side view of the GLA likewise conveys power and serenity. Following the design philosophy, the “dropping line” emerges at the headlamp and extends to the rear wheel arch. The line of the beltline trim gradually rises from the rear door to the C-pillar. Together the light-catching contour on the curvature and the counter-line to the dropping line at side sill height create an interplay of lines that lends the car flowing dynamism and subtle drama. At the sides the cladding follows the contours of the wheel arches and side sill panels into the rear bumper. The side panel has depressions shaped like an excavator’s teeth to accentuate the SUV character. Roof trim strips complete the side view at the top as standard, and as an optional extra aluminium roof rails in high-gloss or polished black are available. On request the GLA is fitted with tyres up to size 19-inch.
The muscular shoulders over the rear axle are emphasised even further by the inward taper of the C-pillars. In combination with the divided tail lights, this emphasises the width of the rear end. Its shape is both dramatic and visually harmonious.
This impression is heightened by the curved rear window and the sweeping chrome handle between the tail lights. Thanks to the divided tail lights, the loading aperture is gratifyingly wide. The large, aerodynamically very effective roof spoiler is another eye-catching feature. It shares the structure of the rear roof cladding and accommodates the third brake light. In the area of the rear bumper cladding there are other SUV-specific features such as an extremely robust external loading sill guard and a simulated underride guard available in high-gloss black, matt silver or silver- shadow.
Interior: attractive design features and high perceived quality
The muscular and imposing appearance of the exterior is systematically continued into the interior. This has a particularly high perceived quality that is achieved by the contours, choice and combinations of high-grade materials. All trim surfaces are galvanised in silver-shadow for material authenticity, resulting in a metallic finish with a “cool-touch” effect. The impression is one of perfect detail. The heavy emphasis on horizontals, the dynamic design and the highly attractive design features are other high-quality attributes. The same applies to the great precision of joints and gap dimensions.
The dashboard consists of an upper and lower section, allowing surface structures that are different in look and feel. Matt and glossy 3D geometries (graining) create an attractive light effect. The three-dimensional trim section of innovative membrane, aluminium or wood lends a new, modern touch to the interior. The matt satin finish of the wood trim is a further enhancement to the modernity, and makes the surface particularly pleasant to the touch.
Five round air vents are integrated into the dashboard. As an exclusive GLA feature, bezels are optionally available around these circular vents whose SUV-look echoes the underride guard and side member claddings. The bezels can be galvanised as an option. The direction of the airflow can be varied by butterfly-shaped inserts which can be optionally galvanised in silver-shadow.
The large, free-standing display has a high-gloss display facing in piano-black and a flush-fitting surround in silver-shadow. This gives the display a particularly high-quality look. A 3-spoke steering wheel with 12 function
keys and a galvanised chrome clasp is standard equipment. On request an instrument cluster version with two tubes is available. In this case there is a small dial instrument in each of the large dial instruments. When at rest the needles are in the 6 o’clock position. The needle inlays are always in silver.
The wide choice of seat upholsteries in material (e.g. leather, fabric, fabric/leather) and colour combinations allows plenty of scope for individualisation. Sports seats with integrated head restraints are
available as an optional extra.
The high quality of the sports seats is emphasised by the aperture in the lower section of the head restraint. On the rear of the front seats this aperture is framed by a surround in silver-shadow, and can have ambience lighting on request. In addition to the equipment packages Style, Urban, AMG and Exclusive, an SUV Style package is available that accentuates the SUV character of the GLA even further. The highlight is robust, colour-contrasting “moccasin” topstitching on the outer seat contours.
If the optional Load Compartment package is ordered, the backrest of the rear seat unit can be moved to a steeper position, the so-called cargo position. This enlarges the load compartment capacity by 60 litres, providing space for bulky items while still allowing the rear seats to be used by passengers.
Set into a galvanised surround, the controls for the optional “electric seat adjustment with memory” are arranged on the interior door panels in typical Mercedes style – a unique feature in this segment. The interior door panels are likewise of extremely high quality. The soft, matt surfaces extend right from the beltline to the door pocket. In combination with the equipment packages the door armrests have a high-quality chrome trim strip and, as an option, ambience lighting.
Aerodynamics: goodbye to box-shaped
With the GLA, yet another model series becomes the leader in its segment with respect to aerodynamic efficiency. Its Cd figure is 0.29. At 0.66 m2 the frontal area Cd x A, which decisively affects fuel consumption from around 60 km/h, is likewise a top figure.
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 step with suitable A-pillar geometry and aerodynamically optimised exterior mirror housings. The rear end is also streamlined. The measures here include the roof spoiler lip and the aerodynamically shaped tail lights. Rear spoilers at the sides ensure that the airflow breaks off for optimal aerodynamic efficiency. Seals in the front bumper (radiator area incl. around the headlamps) and radiator shutters for regulation of the cooling air as required round off the aerodynamic measures.
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 beneath the underbody.
Numerous measures have also been taken to reduce wind noise in the GLA. These e.g. include a multi-level door sealing concept, additional sealing of the joint between the tailgate and the roof and side seals on the tailgate. Particularly rigid window frames prevent the airflow from pulling on the doors at higher speeds, and reduce vibrations. External noise has also been minimised by the low A-pillar step and exterior mirrors connected to the body by a stem.
Engines and transmissions: dynamic claim to leadership
The GLA can be driven with a fuel consumption of only 4.3 litres/100 km, setting new standards in its segment. Modern four-cylinder engines with turbocharging and direct injection, as well as an ECO start/stop function as standard, make for this superior efficiency. The new GLA-Class also takes the lead in its segment with its dynamic performance figures.
Initially the power range of the 1.6 and 2.0-litre petrol engines will extend from 115 kW (156 hp) in the GLA 200 to 155 kW (211 hp) in the GLA 250. The GLA 250 4MATIC sprints from zero to 100 km/h in only 6.5 seconds, underlining the dynamic claim to leadership of the GLA-Class. It has a top speed of 235 km/h and a combined consumption figure of just 7.1 l/100 km (151 g CO2/km – provisional figures).
The two diesel engines excel with dynamic torque and outstanding efficiency: The GLA 200 CDI develops 100 kW (136 hp), a maximum torque of 300 Nm and has a displacement of 2.2 litres. This engine has been reengineered for greater efficiency. The modifications include optimisation of the belt drive, a cylinder head package with different roller bearings and additional finishing, optimisation of the vacuum pump, aluminium pistons with optimised assembly clearances and a low-friction ring package, the roller bearings of the Lanchester balancer shaft and pressure sensor combustion control in the cylinder head.
The GLA 200 CDI requires just 4.3 litres of fuel for 100 km, which equates to 114 g CO2/km (provisional figures). It is rated efficiency class A. The GLA 220 CDI also has a displacement of 2.2 litres, 125 kW (170 hp) and 350 Nm.
All the engines feature the ECO start/stop function as standard. The engines are combined with a six-speed manual transmission or with the 7G-DCT dual clutch automatic transmission (standard for GLA 250, GLA 220 CDI and the 4MATIC models), which unites comfort and sportiness to an outstanding degree.

Suspension: for guaranteed recreational fun
With the new GLA Mercedes-Benz is adding a new member to the successful SUV family. This compact model reinterprets the SUV concept in a new, modern way, because the GLA is less long-legged and imposing than previous SUVs, and therefore fits perfectly into the day-to-day urban lifestyle. At the same time the optional 4MATIC all-wheel drive, the robust body structure and the variable interior concept guarantee plenty of recreational enjoyment. Motto: away from the daily routine. Rough terrain – the beach, loose ground, unsurfaced gradients – all of these are no problem for the GLA.
The chassis of the GLA features a McPherson front axle and an independent multilink rear suspension. Three control arms and one trailing arm per wheel manage the incoming forces. This means that longitudinal and lateral dynamics are independent of one another. The wheel carriers and spring control arms are of aluminium to reduce the unsprung masses. In the versions with 4MATIC, the rear axle carrier is isolated with rubber bushings for the benefit of ride comfort.
Compared to conventional systems, the electromechanical power steering provides better feedback to the driver and makes an important contribution to the vehicle’s overall efficiency, as the servo assistance only requires energy when the vehicle is actually steered. It also allows various steering assistance functions that are initiated by the ESP® control unit. These include countersteering when the vehicle oversteers, steering corrections when braking on surfaces with different levels of grip, reducing the effects of front-wheel drive on the steering and compensation of cross-winds and road camber.
The GLA has an extremely rigid body, and therefore the basis for stable and safe handling characteristics both on and off the road, as well as a high level of NVH comfort. There are additional reinforcements e.g. to the B-pillars, front damper domes, side members and underbody.
High traction reserves: 4MATIC all-wheel drive
The GLA from Mercedes-Benz is optionally available with a new generation of the 4MATIC permanent all-wheel drive system featuring fully variable torque distribution. This all-wheel drive system excels with high traction reserves and outstanding agility combined with superlative driving safety and energy efficiency.
The components of the 4MATIC system include the power take-off to the rear axle that is integrated into the 7G-DCT automatic dual clutch transmission, and the rear-axle gear with integrated, electrohydraulically controlled multi-disc clutch. This set-up allows fully variable distribution of the drive torque between front and rear axles. Additional benefits of this design are a lower system weight than is available from the competition, and high efficiency.
Confident on light terrain: off-road functions
Models with 4MATIC are equipped with DSR (Downhill Speed Regulation) and an off-road transmission mode as standard. DSR is activated by a control button in the centre console, and assists the driver on demanding downhill stretches by maintaining a slow, manually selected vehicle speed within the physical limits when negotiating downhill gradients. This is done with the help of the engine and transmission control systems, and by specific braking intervention.
When the off-road transmission mode is selected using the transmission mode switch, the gearshift points and accelerator characteristics are modified so that the requirements for driving on light off-road terrain and particularly loose surfaces can be met. In combination with Audio 20 CD (standard) and COMAND Online (optional extra), the head unit can also be switched to an off-road display. The steering angle, the selected off-road transmission mode and a compass are displayed there. The roll angle in degrees, the gradient in percent and activation of Downhill Speed Regulation DSR are also indicated.
Smart safety: advanced assistance systems
Numerous driving assistance systems offer support in the GLA and reduce the driver’s workload. Standard-fit features for the SUV include ATTENTION ASSIST drowsiness detection and radar-based COLLISION PREVENTION ASSIST with adaptive Brake Assist, which now helps to protect against collisions from a speed of only 7 km/h.
This feature combines with DISTRONIC PLUS (optional extra) to become COLLISION PREVENTION ASSIST PLUS. This incorporates 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 slower or stopping 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 optional Lane Tracking package with Blind Spot and Lane Keeping Assist or Adaptive Highbeam Assist, are also available for the GLA. Active Parking Assist (optional) allows automatic parking in parallel and end-on parking spaces.
“Always on”: the multimedia systems
The latest multimedia generation deployed in the GLA boasts new functions, additional apps and a modified graphic colour scheme.
Daimler’s Digital Drive Style app concept, which together with the Drive Kit Plus for the iPhone®” allows seamless integration of an iPhone® into the vehicle, has been extended. The highlights include Siri voice control and Glympse real-time location sharing. Glympse enables the user to share his or her current location with selected persons. Additional functions include Facebook®, Twitter®, internet radio, AUPEO!™ personal radio and the advanced navigation system from Garmin® with internet-based real-time traffic information, an online POI search function including Street View™ and a 3D map display.
The COMAND Online multimedia system has also been extended. The latest generation offers improved, photo-realistic map display, an additional Bluetooth® profile (to enable the internet to be accessed via iPhone®, for example, the display of images additionally in bmp and png formats and the real-time transfer of traffic data via LIVE TRAFFIC.
