Mercedes A-class (W169)

I n Mercedes stunned the world by A-class to the world. People not believe Mercedes would such a small car to the market, Volkswagen Golf in the mainstream They were also by its innovative design and packaging a revolutionary sandwich floorpan enables a very compact yet provides a lot of cabin room and crash protection.

Sandwich is probably the most ingenious concept since Sir Issigonis’ It is called Sandwich because the orientated engine is laminated the floorpan and the cabin, just the driver’s feet. As a result, the floor is raised by a massive That explains the A-class’ What is the advantage of such first of all, it allows the to pass any foreseeable crash easily. This is because in of collision the engine will be under the cabin instead of the driver’s legs. Secondly, to this superior crash A-class does not need to a large crumple zone up thus allows an extremely front end and a very compact length. Thirdly, the raised is less obstructed by the front therefore the cabin can be pushed forward to enhance interior

Nevertheless, sandwich structure has its too. It made the A-class too led to the rollover crisis in 1997. eventually solved the problem, but in the it introduced severe understeer and a ride to the A-class, ruining its sweet driving manner. once it restored customer some 1.1 million cars sold.

Now here comes the generation A-class. Mercedes is more ambitious with project, planning to sell examples annually for the following 6 The basic philosophy is unchanged sandwich structure is carried — but this time the is to correct its faults in ride and Without altering the overall Mercedes increased the tracks of considerably (53mm front, rear) to enhance its cornering The torsion-beam rear suspension is an design. It features a Watts for better wheel control, revised geometry put the roll closer to the center of gravity. modifications reduce body a lot. At the MacPherson front a tower brace and a new link anti-roll bars stiffens the structure and separates the longitudinal and forces better, hence steering precision.

All these changes made a big to the handling. The A-class now understeers and controls its body more Body roll is reduced and more progressively, giving its plenty of confidence. The speed-sensitive is beautifully weighted, light at and weighs up at speed. It steers the car yet delivers plenty of feel to the

The combination of extremely compact and light steering is perfect for driving. However, on German the A-class also displays high-speed stability, thanks to the new adaptive dampers. In the twisty, it match a conventional hatchback due to its center of gravity, but then many hatchbacks cannot its fine steering and predictable

And what about ride — the weakest area of the A-class? happily, thanks to the sophisticated suspensions, the new A-class no needs stiff springs and to prevent from rollover. a softer setup and longer suspensions result in a supple, ride. Audi A3 and BMW 1-series be jealous how cosseting and quiet it especially at low speed.

Externally, the new A-class keeps the car’s lovely shape and to cleaner and more streamline. The profile and unique C-pillars are its trademarks, although increasingly by others. An even prettier version has been added, but it measures the same dimensions as the Compare to the Mk1 they are 232mm and 45mm wider. This cabin space a lot — more shoulder room, more front headroom and more rear legroom. Its wheelbase is closer to the old A-class LWB than the old standard car (2423mm). the A-class is actually roomier C-class. This must to the sandwich structure. Luggage now grows to 435 litres. Fold the seat and it expands to 1995 almost like a real

The A-class might look a MPV, but its driving position is by no MPV-like. The vertical steering the tilt seats, the position of and pedals in relation to the driver all like a normal car. what we care most is the quality. In the past decade, was widely criticized for downgraded to boost profit. That was serious for the cabin’s materials and gears. Recently, we saw a revival of in the new SLK. Is it a U-turn in engineering or just an individual incidence? the new told us it is the former. Quality has come back to Mercedes-Benz. at that soft-touch plastic the chromed details, the damped (many comes from the facelifed C-class). this finally deserves the name

In contrast, the engines are perhaps the Mercedes-like. They are not shared other existing models they are designed for mounted and drive the front wheels, in to the company’s tradition of longitudinal / rear-drive. 4 petrol engines are 95hp A150, 115hp 136hp A200 and lastly, a new hot version A200 Turbo produces 193hp and 207lbft. is confident that the new chassis can the extra power. These employ aluminum head, and pistons to achieve a remarkably weight (92kg for A150 and for A200 Turbo). Despite of sohc and 2 valves per cylinder, run at a 11.0:1 compression (thanks to water cooling channels to chambers and sodium-cooled valves) and a intake manifold to enable good power output.

In the diesel side, there are 3 — 82hp A160CDI, A180CDI and 140hp A200CDI. All of are equipped with particle and comply with the strictest EU4 regulation. They also second-generation common-rail injection to power, economy and quietness. the diesel engines have and 4 valves per cylinder, in contrast to the engines. Despite of the names, all displaces 2.0 litres. The most A200CDI employs variable turbine.

Transmission include 5 and manual as well as a new Autotronic It is the company’s first CVT. It has a override with 7 ratios, but important, a torque converter a lock-up clutch should the rubber band effect in ordinary CVTs.

As the turbo version has not yet arrived, the A200 engine mated 5-speed manual gearbox is the one journalists tested at launch. engine is eager, flexible and The gearshift is short-throw and crisp. the rest of the car, the drivetrain is neither sporty nor lazy. It is refined, efficient and highly Mercedes has found the right Unquestionably, the second generation will be another successful but hopefully this time it have a smooth start.
