RS4

Audi RS4

A 420 BHP wolf in sheeps clothing and its based on the quattro drive system, why drive anything else?

Why the fuss?

Sleek lines, all wheel drive and an aggresive looks and nature to go with it A car to battle with the best supercars hunter due to its a performance engine and 4 wheel drive. A sports saloon to break the mould, yet an everyday drive to. An A4 with a difference.
 
The RS4 features FSI technology, and comes with lots of gadgets and even asymmetric / dynamic distribution.

What is it capable of?

Well, the RS4 is 420 bhp at the wheels, its driven by 4.2 V8 that revs to 8250 rpm with ease. This engine is one of the only cars built to achieve 100 bhp per litre - a milestone in car technology. The lump can generate 317 lb-ft max torque which is delivered at 5500 rpm plus the engine is small, 90% of the cars torque is available all the time between 2250 and 7600 rpm. This availability of constant power gives the driver the freedom to drive at lower revs in each gear, therefore minimising wear. The RS is fueled direct fuel injection system, this offers an optimum rate of fuel & air combustion. Giving the auto even more power. This means the RS4 can reach 0-62 mph in 4.8 seconds and 125 mph in 16.6 seconds.
 
Top speed is a healthy 155 mph and thats limited, remove the limiter nad we reckon it will max out at around 190 mph.

Keeping her on the road

Audi's was faced with a few challenges when designing the RS4 and making it work, first problem how to get all the power and acceleration to the road wiithout going through a fullset of tyres in one run.
 
The quattro AWD had proven itself for 25 years on Volkswagen and Audi cars, but somthing new was needed a next gen drive system, research started and before long they had pioneering another technology asymmetric / dynamic torque distribution incorporating a self-locking Torsion centre differential. This car with its new system and the addition of sports suspension could reach unsurpassed dimensions of driving, Audi even added DRC (Dynamic Ride Control) this reduced body roll and dive making the automobile more stable.

Brakes we need, brakes!

This serious piece of kit needed some awesome stopping power, 18-inch cross-drilled, inner-vented brake discs were added - The front measure 365 millimeters in diameter, and the back were 324-millimetre diameter. They even thought of the best way to keep them working constantly, by adding a flow-optimized ventilation system combined with underfloor Naca jets, this provided high levels of cooling, ensuring the brakes stayed at an optimum tempertaure.

Just take a look

This car is like no other A4 saloon one look defines this, the radiator grille, has a diamond design, air scoops, and custom wheels developed for the RS4 specifically. There has been a new air dam added as well as extra-large exhaust pipes discreetly fitted in keeping with true euro style, a spoiler hides in the boot lid all blended with Audi's sleek lines. Its been lowered by 30 mm, and the car’s track has been widened to give a more sinister stance.
Feel a $1,000 000
 
The RS4 comes with an executive level of luxury aluminium, carbon fibre and leather to create the perfect driving machine.
 
The Racing bucket seats are full leather, with high sides for the ultimate support and a button to inflate the side supports to mould round your body contour. As for a race feel you will find a sports steering wheel, starter button and aluminium racing pedals.

I told you not to open it

Well go on, one button and it opens all, control the fuel pedal control map, the result sharper acceleration and a direct response.

The Audi Quattro

All wheel drive

The Audi Quattro, this car single handedly changed the course of rallying history, the car has great historical significance as a Rally and road car. It is special due to it only the second car to feature AWD the first being the Jensen FF in 1966.
 
The car model name is "Quattro" using a capital Q, this is differentiated between the drive system signified as a lowercase q.
 
The original Audi Quattro first saw life in 1980 was released in 1980, it was the first auto to combine a Turbo charged engine with an All Wheel Drive System. The engine was was a 2.1 Litre, with a SOHC, this featured a 10 valve straight-5 setup, with 160 bhp. As the models progressed so did the break horsepower creeping up to 200 bhp twin cam. The Quattro UR is recognised as a milestone rally car, and it took advantage of rally rule changes allowing cars to run all-wheel-drive.
 
 
The car and its setup was doubted by rally critics it was believed there heavy body & complexity would slow them down, how wrong could they have been. It was an instant success, the first rally it participated it won, and from that day it fully dominated for the next two years.
 
11,000 road cars were produced cars between 1980-1991. The Audi body style had very few body changes, from 1985 a new sloping front grill, headlights, trim and new badges were added.
 
All VAG's ( Volkswagen Audi Group) Quattro cars were built in Germany by a specialist Audi divisionhand by hand, the division included specialist engineers, developers, mechanics and researchers.

Quattro - Sport

The Sport Quattro was developed solely for Group B rallying, however as it was a rally car a production car had to be offered, this version was a limited edition model with a significantly shorter wheelbase. This model is very rare, lighter than other models rally tuned and demonstrates optimum handling and extreme power.

 

Audi S8

Audi S8 Quattro

A luxury saloon with immense power made famous by its part driving round Paris and the South of France in Ronin.
 
 
The S8, a V8 with a difference, performance, luxury and styled aggresively. This car is basically the same as the A8 with quattro - all wheel drive and an aluminum space frame, but thats where the similarities end comes this monster of a car features aluminum uprated sports suspension, all round vented brake discs front 13.6 inch and the rear 11 inch, Brembo aluminium brake calipers finished off with 18-inch Avus alloys with 245/45ZR18 rubber all as standard.
 
 

An engine to match

 
The engine is the same as the A8 saloon, a V8 with a 4.2 capacity, but with one difference it has 60bhp. This in mind the S8 has been lowered all round by 20 mm than the standard A8, the shocks have been stiffened 30 percent more and the springs uprated and the compression damping is 40% higher with thicker stabiliser bars therefore giving considerably more grip increasing handling balance dramatically (0.88g on the skidpad vs. 0.77g for the A8) hhhhhhhhhhhhhhhhhhhhwith a harsher ride. The car has light power steering, however its agility still keeps it bounds ahead of its closest competitor, the Mercedes SL55 AMG.
 
The S8 comes equipped with some extremely good safety features including an electronic differential lock (EDL) this and the brakes combined provides a targeted force distribution to the wheels with a great degree of traction, also there is ESP electronic stabiliser program, ASR traction control, ABS brakes and 8 airbags.
 
The Audi S8 Quattro runs a six speed manual transmission, in the US a Tiptronic Gearbox replaced the 6 speed manual and has a few exterior differences from the A8 though hard to spot chrome door mirrors, a chrome-lined air intake, exclusive wheels, red and silver motor sport emblems front & rear.
The inside is fitted with Nappa leather, heated mirrors, power everything, cruise control, solar panel glass sunroof, system GPS, remote security system with alarm & immobiliser, electric rear sunblind, a nearside mirror tilts down when reversing, 10-speaker BOSE sound system with CD Shuttle and numerous other features.

S1 Evo

S1 EVO

The S1 Evo an all wheel drive 450bhp World Rally Championship car.
 
 
The S1 with its quattro drive system dominated rallying. Walter Röhrl went to victory in the 1st ever rally it was entered in, in San Remo Rally, Röhrl won 29 out of 45 stages.
 
When Group B rallying was banned in 1987 this car and many other suffered, such cars as the Ford RS200 and the Audi S1 Evo days were numbered. Röhrl wasn't beaten though and went onto enter the car in the Pikes Peak hill climb, he dominated the climb and went onto victory.
 

Audi History

Audi guide

The 'Four Rings' formed 1899

Back in Zwickau 1909, August Horch came up with an idea, Audi. This name is still the original trading name since 1910.
 
In German 'Horch' translates as Listen! To this day this remains Audi's policy and has always been paramount. There goal was to build and design for the luxury car market. This success was achieved in the International Austrian Alpine Rallies, 1912 was when the victories started and continued to 1914, this confirmed that high performance matched with luxury would give the German company a winning brand.
 

1909 Horch & Cie

In 1909 there was in a dispute between August and the Supervisory board of A. Horch & Cie - Motorwagen-Werke AG. Shortly after Horch left what he had created.
 
However, on in 1909 on July 16th he fomed a second company Horch Automobil-Werke GmbH, in the same city as a direct competitor. August tried to fight for previous name but lost the legal battle. A solution presented itself: the Latin translation of Horch (German for “hark!”) Audiwerke GmbH, starting on April 25th 1910.

Left hand drive

This was the dawn of the left hand drive motor car, up until now Right-hand drive had been as common as horses and carriages. In 1921 September Germany's first ever car manufacturer, Audi. became pioneers of another commonly seen idea.
 
The company became the first to release a left-hand drive production car, the Type K. This new position gave drivers a greater view of the road making it easier to see oncoming cars & hazards it also making it safer to overtake, by the turn of the 1920's this was the standard.

8 Sport Cabriolet

In 1927, The 8 Sport Cabriolet was released a two door car with two side windows with two Dickey seats in the rear.
 
1932, brought the Type 780 the equivalent to the 8, this car suceeded sucessor, inturn the 853 was released due to popular demand.

Wanderer W25 K

A performance sportscar with a relatively high top speed and extremely responsive acceleration. The W25 K was inspired and designed by Ferdinand Porsche, with its 2 litre 6 cylinder engine it was capable of 85 bhp, this was aminly due to its supercharger. This new, US influenced racing car, performance and styling were inspired by the W51. This car went onto create the backbone of Auto Union's range.
Audi 100 Coupé S
 
The Audi 100 Coupe was released after the saloon version. The new model featured flair and a contemporary Italian design, it was debuted at the Frankfurt Motor Show in September 1969. The Coupe Scame came standard with wide tyres, adjustable steering wheel, vented front discs and a limited edition interior.

Audi Quattro

The Audi Quattro made its first appearance at the 1980 Geneva Motor Show. It was the first car to demonstrate four wheel drive as a permanent drive system.
 
The car as soon as it was released dominated Rallying with its 4 wheel drive system known as quattro, note the lower case q, the system it utilised was already used by off-roaders such as Land Rover. The combination of a sports saloon with 4 wheel drive uprated suspension and racing rims was a triumph. The basic principle was a hollow-shaft designed central differential, that allowed power to be fed between both the front & rear axles of the auto.
 
After the introduction of this new system, the German car manufacturer went from strength to strength, intrun releasing an array of performance all wheel drive cars these included the S8 and Audi RS 4 & RS 6.

The new millenium

The RS models released through out the last eight years have dominated their various car markets, with such cars as the RS4, but now the new series of R autos are with us, named after the Le Mans styles racing cars. Theses include the R8 the R4 even maybe an R10 and more recently the A1 and Q7 SUV.

The R8

This flagship Audi Supercar was released in 2007, a car like no other it comes with a mid mounted V8 Lamborghini Murcielago engine. This cars contniues to astound with more and more models being released, including a convertible roadster and an Audi R8 LM model.
