Manufacturer Mercedes-Benz
Production 1997–present
Class Mini MPV
Layout Front-engine, front-wheel drive

The Mercedes-Benz A-Class is a mini MPV produced by the German automobile manufacturer Mercedes-Benz. The first generation (W168) was introduced in 1997, and the all-new second generation model (W169) appeared in late 2004. Launched as a five-door hatchback in 1997, the second generation W169 introduced a three-door hatchback to sit below the five-door. In the markets that the A-Class is or has been sold in, it has represented the entry level model of Mercedes-Benz.

Some consider the creation of the A-Class to have reduced the prestige of the Mercedes-Benz brand, especially in Europe.

Production of the W168 A-Class began in 1997. Its front engine, front wheel drive layout was quite unusual for Mercedes. To date, about 1.6 million units have been sold worldwide.[1]

One innovation of the W168 was a frontal-impact absorption system called the "Sandwich" (see patents DE4326 9 and DE4400132 in the name of Mercedes-Benz). In the event of a violent frontal impact, the engine and transmission would slide underneath the floor below the pedals rather than entering the passenger compartment.

The W168 became infamous in 1997 after flipping over during the traditional "elk test" performed by the Swedish automobile publication Teknikens Värld. According to the report, the W168 overturned when manoeuvring to avoid the "elk". Mercedes initially denied the problem, but then took the surprising step of recalling all units sold to date (2,600) and suspending distribution until the problem was solved by adding electronic stability control and modifying the suspension.

Mercedes-Benz facelifted the W168 in 2001.

DaimlerChrysler invested EUR 900 million in developing the Rastatt plant where the A-Class is produced, and created 1600 new jobs (for a total of 4700). A further 600 people work on the industrial estate at the plant site.

Mercedes-Benz began W168 production on 17 February 1999 at its new Brazilian facility in Juiz de Fora, Minas Gerais. The Brazilian plant was the company's first factory in South America dedicated to passenger cars, with an investment of USD 840 million and 10,000 employees. The factory initially produced A-Class and C-Class models, assembling them from pieces manufactured in Germany. The target for the cars was regional markets (from Argentina to Mexico) with modifications made to the cars to suit local conditions, like a protection for the motor base. On 15 August 2005 the factory stopped production of A-Class cars.

Wheelbase 2,568 mm (101.1 in)
Length 3,838 mm (151.1 in) (2004)

The W169 is constructed with high-strength steel alloys with bonded joints. It has a large number of airbags including optional rear side airbags (for side-impacts in the backseats), optional side-curtain airbags, and standard head and thorax-protection side airbags. The front airbags are adaptive with two-stage gas generators operating according to the severity of accident.

The force exerted by the seat belt system during a collision adapts dynamically depending upon the collision characteristics. The 'active' head restraints (standard for driver and front passenger) give enhanced protection from neck injury, especially during rear collisions.

The angle of the A-pillar is flatter than the windshield angle. The cargo capacity of the W169 was increased by 15 percent compared with the W168.

Seven types of motors are available, and all are four-cylinders: four petrol (gasoline) (A 150, A 170, A 200, A 200 Turbo) and three diesel (A 160 CDI, A 180 CDI, A 200 CDI) partnered with either five- or six-speed manual gearbox. A continuously variable transmission system called "Autotronic Constantly Variable Transmission" (CVT) is an optional feature.

The petrol A 200 Turbo provides 193 hp (144 kW) and 280 N·m (207 lb·ft) of torque (rotational force); the diesel A200 CDI has 140 hp (104 kW) and 300 N·m (221 lb·ft).

The most powerful model can take the car from a standstill to 100 km/h (62 mph) in 8.0 seconds, and has a top speed of 218 km/h (135 mph). The newly developed direct-injection CDI diesel units use a common-rail direct injection system that improves fuel consumption and reduces exhaust emissions and noise levels.

All the engines meet the tight EU4 emissions limits. A particulate filter system is available as an option for the diesel units which reduces the particulate emissions by about 99% without the need for additives.

The A-Class is a front wheel drive car and features traction control (ASR) as standard, as well as electronic stability control and anti-lock brakes (ABS).

Handling is improved by precision tracking and anti-roll support, and by a Parabolic Rear Axle.

A "Selective Damping System", in which the shock absorber forces respond differently according to conditions, is standard. For example, under normal conditions it operates at soft absorption; while cornering at speed it changes to full damping force.

The W169 optionally comes with light-alloy wheels, with a run-flat feature, Tirefit tire sealant and a tire-pressure-loss warning device.

A four-day, seven-country tour which officially introduced the car culminated in an event in Milan, in the Castello Sforzesco, where all the touring units were received by a myriad of European personalities from music, fashion, sport and movies. Armani presented a fashion show and Christina Aguilera did a live performance of her song "Hello", composed exclusively for the occasion. The W169 advertising campaign included television spots with Christina Aguilera, Giorgio Armani and Boris Becker.

Sales of the W169 were targeted at 50,000 units in 2004. Dr. Joachim Schmidt, Executive Vice President Sales and Marketing, Mercedes Car Group, said that target had been reached even before vehicles arrived in dealer showrooms.

Facelift

The W169 facelift shown in the spring of 2008 and on the road that year, features redesigned front and rear bumpers, new tail lamps and headlights, new grille, new exterior mirrors, a restyled interior design and new upholsteries and colours. The 2009 A-Class was released alongside the refreshed 2009 M-Class and B-Class. The car is also available with Active Park Assist, which enables the car to parallel park itself, with only throttle and brake inputs required from the driver.

Electric versions

The "e-mobility Berlin" project will see Daimler deploy a fleet of over 100 second-generation Smart ED and Mercedes A-Class cars powered by lithium ion batteries.[2]

Mercedes A-Class E-Cell

The Mercedes A-Class E-Cell was introduced in September 2010 and debuted at the October 2010 Paris Motor Show.[3][4] The E-Cell has a range of 200 kilometres (124.3 mi) capable of developing a peak output of 70 kW (94 hp), a continuous power rating of 50 kW (67 hp) and a maximum torque of 290 N·m (214 ft·lbf). The Mercedes A-Class E-Cell can accelerate from 0-60 km/h (37 mph) in 5.5 seconds, and its top speed is 150 kilometres per hour (93 mph).[3][5]

Tesla Motors, as part of its collaboration with Mercedes-Benz, is building electric powertrain components for the E-Cell. The 36 kWh battery contains approximately 4,000 individual lithium-ion cells.[3][6][7] Mercedes has developed a modular system for electric vehicles with battery and fuel-cell. This system allows the efficient use of shared parts in all the brand's electric vehicles. Thanks to the modular approach the electric drive of the A‑Class E‑Cell is also used in the B‑Class F‑Cell, and the energy storage units in the A‑Class EV are the same as the battery in the Smart fortwo electric drive.[3][5]

A limited production of 500 A-Class E-Cell electric cars will be built, for trial purposes, at the Mercedes Rastatt plant, near Stuttgart beginning in September 2010. As part of a demonstration program, the cars will be leased to selected customers in several European countries, including Germany, France, and the Netherlands. Daimler is not planning to sell the electric version outside of Europe.[3][5][8]
