Astounding: Did you know that...

…the CLA holds a world record for aerodynamics? In 2013, the four-door Coupé set a new record with a Cd value of 0.23 – not only within the Mercedes model range, but also amongst all standard-production vehicles. The good air flow characteristics result from numerous aerodynamic optimisation measures, including patented wheel spoilers on the wheel arches developed with the help of flow calculations.

…Active Brake Assist has reduced serious rear-end collisions by up to 30 percent? When launched in 2011, the B-Class was the first vehicle to feature this radar-based assistance system as standard (called COLLISION PREVENTION ASSIST at that time). To arrive at their forecast, the Mercedes-Benz accident researchers evaluated figures from the Federal Office of Statistics and simulated digital accident data in 2014.

…the Mercedes-Benz Rastatt plant is celebrating its 25th anniversary in 2017? The E-Class was the first model to be produced at the Rastatt plant, followed in 1997 by the A-Class and the start of the compact-car success story. Rastatt is now the lead plant for the Mercedes-Benz compact cars in the global production network. The Rastatt plant will also produce the next generation of compact cars.

…the workforce at the Hedelfingen section of the Untertürkheim plant produced the one-millionth dual clutch transmission on 21 June 2016? The Hedelfingen section produced the first 7G-DCT transmission in 2011. The Mercedes-Benz Untertürkheim plant looks back on more than 110 years of tradition and is the lead plant in the global powertrain production network. With more than 19,000 employees, the plant produces engines, axles, transmissions and components.

…LED High Performance headlamps place less strain on the driver's eyes? Because their colour temperature is closer to that of daylight than xenon headlamps, for example. The 34-watt LED low-beam headlamps also have very low energy consumption – around 60 percent less than xenon and around 70 percent less than halogen. Following the facelifts, LED High Performance headlamps are available as optional extras for all compact cars with petrol or diesel engine.

…the suspension with Adaptive Damping System (optional extra) was developed with the help of virtual test drives among other things? Before road-ready prototypes became available, the suspension experts fed the ride simulator at the development centre in Sindelfingen with the surface data from real-life test routes and the corresponding suspension data of the adaptive damping system of the A-Class. In this way, it was possible to conduct virtual test drives with the new suspension on the two seats of the ride simulator at an early stage of the development process – followed by the usual extensive test programme.

…the B-Class was designed for alternative drive systems from the start thanks to the "ENERGY SPACE" modular concept? Various interface points in the body shell make it possible to modify the main floor for the versions with alternative powertrain and to exploit use of a partial double floor beneath the rear bench seat. This underbody houses one large and two smaller natural gas tanks (B 200 c) or the lithium-ion battery (B 250 e). Due to this intelligent packaging method, the five-seater model has been able to retain the generously proportioned luggage compartment for which it is known – and these versions can be produced together with the other B-Class models.

…the 500,000th Mercedes-Benz "made in Kecskemét" left the factory on 9 February, 2016? The landmark vehicle was a cosmos black CLA for a Hungarian customer. The new compact-car generation will also be produced in Kecskemét.

…the compact models incorporate engine technology from the S-Class? The technology package in the four-cylinder petrol engines includes a number of new developments such as third-generation direct injection featuring highly precise piezo injection technology with multiple injection, which was introduced for the V6 and V8 engines in the Mercedes-Benz S-Class in 2010 and is now available in the compact class for the first time.

…the drive systems available for the compact class have outputs ranging from 66 kW (90 hp) to 280 kW (381 hp)? That's the output of the 2.0-litre turbocharged engine in the Mercedes-AMG models – the world's most powerful four-cylinder engine in series production.

…some 180,000 customers visit the Rastatt plant every year? They go there to participate in one of the 2500 guided tours of the plant and/or pick up their new vehicles (around 250 per day). The latest attraction is the "A-Rock" driving experience course covering an area of around 10,000 m2. The highlight is a hill, the "A-Rock", with a uphill gradient of 60 percent and a downhill gradient of 70 percent on the other side. In addition to the off-road course, there is a driving dynamics area in which customers can actively experience the various assistance systems in their new cars when they come to pick them up.

…around 200 young people are doing their training at the Rastatt plant? These young people can choose from six technical careers, one commercial option and four dual study courses. The trainees are able to gain experience abroad at the sister plant in Kecskemét/Hungary.

…the 4MATIC models in the compact-class family always feature the 7G‑DCT seven-speed automated dual clutch transmission? The power flow to the rear drive train is provided by a compact power take-off unit (PTU) which is fully integrated into the main transmission and supplied with lubricant from the latter's oil circuit. This configuration gives rise to substantial weight advantages over competitor systems that branch off power by means of an add-on component with its own oil circuit. The hydraulically actuated multi-disc clutch integrated into the rear-axle gear unit is responsible for fully variable torque distribution.

…a new logistics concept was implemented at the Kecskemét site in 2016? The development was part of the digital transformation: there are no longer any shelves holding boxes and parts on the production line. Automatically guided vehicles (AGVs) bring the shopping carts from the picking zone in the logistics centre to the production line automatically. The crew at the various stations on the line then remove the parts that are required and install them in the vehicle.

…the B-Class was the first vehicle in this class to offer the preventive occupant protection system PRE-SAFE® when the car was launched in 2011? Core features of PRE-SAFE® include reversible belt tensioning, the closing of side windows and sliding sunroof in the event of critical lateral dynamics, and adjustment of the fully electric front passenger seat with memory function to an ideal position for maximum effectiveness of the restraint systems. PRE-SAFE® is generally activated in the event of critical longitudinal and lateral dynamics, but it can also be triggered when certain assistance functions intervene.

…the ATTENTION ASSIST drowsiness detection and warning system fitted as standard in the compact-class vehicles registers over 70 parameters, which are evaluated for drowsiness detection? This continuous monitoring is necessary to register the transition from wakefulness to drowsiness, and to warn the driver in good time. Based on this wealth of data, ATTENTION ASSIST calculates an individual driver profile during the first few minutes of every trip. This profile is then compared with the current sensor data and the prevailing driving situation by the car's electronic control unit. In addition to the speed and the longitudinal and lateral acceleration, the Mercedes system also detects turn-indicator and pedal activations as well as certain control actuations and external influences such as cross winds or uneven road surfaces.

…the 2.0-litre four-cylinder turbocharged engine for the Mercedes-AMG compact models is assembled purely by hand at Kölleda, in accordance with the traditional AMG philosophy of "one man, one engine". The engine plant started producing AMG engines in 2013.
