A-Class

2001 July, right: The update Mercedes A-class now in Australia; the new grille and nose & tail details are most noticeable, but the brakes now have `brake assist' (as well as ESP). Window airbags are optional. The air conditioning is said to have an "additional air humidity sensor".

The model line includes an "entry level A 160 Classic, [...] with 15-inch alloy wheels, and A 190 Elegance."

A160 Classic: 1589cc, petrol, 4-cyl, 75kW, 5-speed manual +auto clutch, $34,000 (Elegance +$3000).
A190 Elegance: 1898cc, petrol, 4-cyl, 92kW, 5-speed manual +auto clutch, $40,900.

2001 February: Mercedes-Benz has requested that owners of A-class models built between September 2000 and January 2001 visit their workshop. "A modified rubber seal in the master brake cylinder [used] from September 2000" can cause increased brake pedal travel "in individual cases, and only at temperatures below freezing point." Mercedes-Benz will replace the master brake cylinder at no cost.

2001 January: The Mercedes Benz A-class is to get a mid-term revision in spring 2001 (northern hemisphere). The look is slightly changed by a new front bumper cum spoiler with basically a bigger hole under the number plate. This, and changes to the rear bumper, increase the length by 31mm. The wheels also have thinner "spokes".

Safety features include "latest-generation ESP and optional windowbags." The new electronic stability program makes "the use of a hydraulic Brake Assist system" possible.

Options include a humidty sensing air conditioning system, and rain sensing windscreen wiper controls.

2000 January: The entry-level A140 to be priced at $32,900 ($au). This includes air-conditioning, central locking, dual airbags, ABS brakes and ESP as standard.

1999 September: Mercedes-Benz (au) added the A190 with a 1.9 litre 4-cylinder engine to the local A-class range. Its power, 92kW, is well up on the A160's 75kW. The A190 comes in the Avantgarde (top) level of trim. A top speed of 198km/h and acceleration of 0-100km/h in 8.8 seconds are claimed. Closer gear-ratios are fitted to the 5-speed manual gearbox to go with the sporty image; ditto 195/50R16 tyres on 16" alloy wheels. Prices are "$43,900 for the auto-clutch manual and $45,400 [$au] for the 5-speed automatic with tip-shift manual control."

Mercedes-Benz report that over 157,000 A-class have been sold in Europe since the start of 1999, and over 1000 in Australia, to August 1999.

The diminutive Mercedes-Benz A-class has a clever design to maximize the use of space: The front-mounted engine & gearbox unit slopes forwards partly underneath the passenger compartment - which also increases safety as it is pushed down and backwards in an impact. A dual-skin floor further improves crashworthiness. The rear seats can be folded or even removed to enlarge the load carrying area.

ABS anti-lock brakes, BAS brake assist system, and ESP electronic stability program are active safety features. BAS generates more brake pressure if the brakes are suddenly applied, as in an emergency. ESP modifies brake pressure at wheels selectively to reduce under- or over-steer (skids). (An embarrassing roll during a pre-release "Moose-test" caused MB to widen the track and fit ESP.)

Passive safety features include front and side airbags, seat-belt tensioners & load limiters, and the body design mentioned above.
