Audi Q2

The Audi A2 (internally designated Typ 8Z)[1] is a lightweight compact MPV-styled supermini car, with a five-door hatchback body style and four or five seats,[1] produced by the German manufacturer Audi from November 1999 (for the 2000 model year) to August 2005.[1] Based on the Audi Al2 concept car first shown at the Frankfurt Motor Show in 1997,[3] the A2 was notable for being constructed from aluminium, which in combination with its efficient engines made it highly fuel efficient.

Sales were disappointing, and the car was taken out of production in 2005.

History

[edit]

The A2 was produced at Audi's "aluminium" Neckarsulm plant in Germany on a special line purpose-built for it.[1] It was the first five-door vehicle on sale in Europe with an average fuel consumption less than 3 litres per 100 kilometres (94.2 mpg‑imp; 78.4 mpg‑US), although these figures only applied to the special "3L" version with a diesel engine, automatic gearbox, stop-start system, less power and narrower tyres. Due to its construction, the average A2 weighs 830 kg. The last A2s to be produced were built in August 2005.[1]

Styling

[edit]

The A2 was a surprise when it debuted only two years after the original Al2 study. Many initial reviews, including those from What Car? and Autocar in the UK commented on the design.

Autocar's initial drive verdict

[edit]

"The best thing about the A2 is that it isn’t merely a design exercise. Yes, it’s a great car to look at, sit in and touch, but it’s also a riot to drive".[4]

The avant-garde styling did not, however, win favour with some potential customers. Audi was reported to be disappointed with the level of sales. The final production was only 176,377[5] units, in comparison to rival Mercedes-Benz's A-Class sales of 1 million.

Design, engineering and construction

[edit]
Audi A2 (side view)

The overriding theme in the design and engineering of the A2 was summarized by the then Audi UK product manager in an interview after the car won a design award in 2001 as "create a small Audi, not a cheap Audi",[6] and the creative brief is said to have been "Transport four people from Stuttgart to Milan on a single tank of petrol".[6]

The A2 is built with a considerable amount of aluminium and aluminium alloy, making it weigh significantly less than cars of this size, and use much less fuel than cars with traditional steel monocoques. Under certain circumstances, consumption for the 1.2 TDI model can be as low as just over 2 litres per 100 kilometres (140 mpg‑imp; 120 mpg‑US). This version of the Audi A2 won the "Nordic Eco Run" fuel economy race in 2003, with a consumption of 2.62 L/100 km (107.8 mpg‑imp; 89.8 mpg‑US).[7] Even the normal versions with petrol engines are capable of 5 L/100 km (56.5 mpg‑imp; 47.0 mpg‑US). The A2 was also notable for being the first Audi model since the 1970s Audi 50 (type 86) and Audi 100 (type 43) not to be offered with its 'trademark' quattro four-wheel drive option. The A2 has a coefficient of drag of between 0.25 and 0.29, depending on the specific version.[8]

The A2 still uses a contemporary unibody construction, with significant elements of space frame principles,[9] and it is tagged by Audi as an 'Audi Space Frame' design. The outer panels of the body have little or no structural function – similarities exist with the original Renault Espace – and the space frame bears the forces working on the car. The frame uses casts and extrusions which are laser welded together to make the space frame. Improvements in shell stability, durability and stiffness, lower weight, and more interior space are results of its construction. "The A2, on the other hand, was designed as an aluminum car and the spaceframe has been optimized by parts consolidation, using large, cost-effective castings instead of aluminum stampings".[9]

Unfortunately, the cost of working with aluminium, particularly with small production runs, meant that the A2 was more expensive than other cars in its sector, competing with the A-class and losing. Much of the high production cost was due to so many parts not being "off the shelf" and being specifically optimized for the A2.[10] From Autobild in 2003: "The A2 is not one of the models with the highest return on investment". The same article quotes the sales figures for 2002 as being 20,000 in Germany against 80,000 for the A-Class and "...lots of money for a car that is only 3.8m long."[11]

Audi was the first manufacturer to try to incorporate lightweight building concepts using aluminium and associated alloys into a "mass market" vehicle.[citation needed] Previous efforts at using the Audi Space Frame were limited to the rather more expensive Audi A8. As a guide to the mass involved, the entire shell weighs so little that two people can easily pick it up, and the side panel over the doors including the A- and D-pillars weighs approximately 2 kg (4 lb). A 2002 model A2 with standard equipment has a mass of 895 kg (1,973 lb).

Interior

[edit]

The A2 has a large interior space for the exterior dimensions, including a boot with 390 litres (13.8 cu ft) of space when the rear seats are in place. This is significantly larger than the luggage space of the next model in Audi's range, the Audi A3. Due to the "sandwich"-type construction, similar again to that of the Renault Espace or the Mercedes A-Class, the floorpan has an upper and a lower portion. The space in the middle is used to house various components, such as the fuel tank and the engine's electronics. The rear passengers also benefit, as their foot space reaches into this sandwich space, creating a comfortable seating position even for tall rear seat passengers. This is in direct contrast to the comfort available on the rear bench of an A-Class. To improve the weight distribution of the vehicle, its battery is located inside the boot, under the floor.[citation needed]

The A2's interior was very upmarket in comparison with other superminis.[citation needed] In both the UK and Europe, there were several choices of seat material and colour, comprising the standard Cirrus cloth, optional Matrix cloth, optional Alcantara/leather, or full pearl Nappa leather seat coverings. Sport models received sport seats with electrically adjustable lumbar support as standard in jacquard satin cloth.[citation needed]

Service hatch (Serviceklappe)

[edit]

The front of the car included an unusual design feature called the "Serviceklappe" in German – this translates to "service hatch" or "service panel". On early cars, this was a glossy black panel at the lower edge of the bonnet, where the radiator grille would normally be sited. Behind it are the filling points for oil and windshield washer fluid, and the dipstick.

The bonnet was widely rumoured to be sealed – Car and Driver wrote: "...feature of the A2 that may foretell the future: the sealed hood". Actually, the bonnet is easily removed, being held in place by two twist-lock catches. The bonnet, weighing 8 kg, then comes away from the car altogether, unlike the usual hinged flip-up arrangement on most other cars. Due to the service hatch, the bonnet does not need to be removed frequently for access to the engine.

Facelift and additional models

[edit]

The service hatch is the most obvious indicator of the age of any particular A2. It was changed to matte black for the "color.storm" colour schemes, and for model year 2004 it acquired fake grille slats. However it can be changed easily, so it should not be taken as a reliable age indicator.[12] Very little else was changed externally during the life of the car. Colours and wheels designs were changed mildly during the production run. The only other external indicator of the age of the car is the windscreen wiper. Very early models have a traditional blade, but starting in model year 2002, newer cars have a "flex" version ("Aerotwin" from Bosch, model 760).

2005

[edit]
  • Special Edition (including CD player and climate control) models introduced into UK markets, at this time no other models were available in the UK
  • Audi lost an estimated £4,000 on every A2 they sold and only made money on cars with optional extras. Continued production of the model was reviewed by the board of directors
  • Production of the A2 is halted by VW/Audi group boss Bernd Pischetsrieder.[14] Overall, Audi lost €7,530 per vehicle produced.[15]

Lekker/DBM electric version

[edit]

In October 2010, an A2 converted to electric power by Lekker Energie and DBM Energy completed an early morning 600-kilometre (370 mi) drive from Munich to Berlin on a single charge. Upon arrival, Rainer Bruederle, Germany's Economics Minister, called the test drive a "world record."[16]

The car was said to still have 18% of its charge remaining on arrival in Berlin and the average speed was reported as being 90 km/h (56 mph). The "kolibri" batteries used in the design are so compact that the vehicle retains its four seats and boot space. A production version would be possible. "The technology could be implemented today. It is up to industry to use this potential," commented Mirko Hannemann, the head of DBM.[17]

1.2 TDI "3L"

[edit]

The Audi A2 1.2 TDI had the lowest drag coefficient of any car in the world at the time of its launch.[18] It was also one of the most economical and least polluting, only emitting 81 g/km (German emission standard D4) to 86 g/km (D3 emission standard) CO2 emissions. The Audi A2 3L reuses the engine and special gearbox developed for the equally efficient Volkswagen Lupo 1.2 TDI 3L.

Two versions of the car were available in Germany during its production run. The D4 version, which used only 3 L/100 km (94 mpg‑imp; 78 mpg‑US), was "standard." It had no power steering, air conditioning or other extras, with the only optional extra being body coloured door handles and wing mirrors. There were no optional extras because optional equipment adds weight and therefore reduces economy. It had a fixed rear seat cushion. The tested fuel economy was 2.88 L/100 km.[citation needed]

The second version was a D3 version which was still capable of 3.0 L/100 km. This version had options for air conditioning, a winter package, and a comfort package, but was not available in all markets.[citation needed]

Both versions had thinner glass, lighter seats,[19] and 14" magnesium alloy wheels. The standard tyre fitment was 145/80 R14 T76 Bridgestone Ecopias or Continental Winter Tyres using very flat wheel covers to minimize turbulence. The engine block was also made from a light alloy, so even though it was a diesel, it weighed just 100 kg (220 lb).

The car had an automated manual transmission with a Tiptronic mode on the selector. The car also had an ECO mode. When engaged it limited the power to 41 bhp (31 kW; 42 PS) (excluding kick down) and programmed the transmission to change up at the most economical point. ECO mode also activated the start/stop function, a feature that was new to European cars at the time.[20]

A total of 6450 1.2 TDI models were built. [5]

A2 Concept (2011)

[edit]
2011 Audi A2 concept car

At the Frankfurt Motor Show in September 2011, Audi exhibited an entirely electric concept car, the A2 concept, previewing an expected new A2 production model. The superstructure made largely from aluminium, additional parts in Carbon Fibre-Reinforced Polymer, and other construction techniques restrain the weight to only 1,150 kg.

A lithium-ion battery placed between the floor holds 24 kWh of usable charge. An electric motor is transversely mounted at the front of the vehicle, the electric motor delivers through the front wheels and uses a single-speed transmission. The vehicle will also incorporate shift-by-wire, brake-by-wire and steer-by-wire contactless technology, and LED matrix technology for the headlights and tail lights.[22]

In June 2012, the UK's Car Magazine reported that Audi had put the electric A2 project on hold indefinitely, following disappointing European sales of other EVs, like the Nissan Leaf & Mitsubishi i-MiEV, and a projected retail price of over €40,000.[23]

It was reported that, according to the director of e-mobility and sustainability strategy at Audi of America, the A2 electric concept was not a developmental prototype with a test program, but a one-off concept car to be shown at auto shows.[24]
