Welcome to London's Audi Specialists.We have a team of Audi specialists who can sort out anything from basic Audi servicing to advanced technical Audi cars problems. One of the best Audi Master Technician on site offering knowledge and experience using the latest Audi Main Dealer compulsory diagnostics equipment.

Six weeks after its Nürburgring appearance, Audi continued the design theme “Past – Present – Future” with new livery designs at the 2023 Spa 24 Hours. The R8 LMS cars also took center stage in Belgium in terms of the results on track: The brand won the prestigious “Coupe du Roi” trophy as the best manufacturer in the race, which is the world’s biggest GT3 race and takes place on the famous Grand Prix circuit at Spa. At the Family Day hosted at Böllinger Höfe on July 8, tens of thousands of people experienced Audi Sport GmbH as a particularly dynamic part of the four rings, which included, for example, taking rides in the Audi R8 LMS race car and the RS Q e-tron prototype for the Dakar Rally.

Sales records with future-focused model strategy

The Audi RS e-tron GT ice race edition, which was presented in September 2023, is currently the creative highlight of the model program. Limited to 99 units, the special edition of the first all-electric RS model embodies a new innovative expression of individualized design. Together with the 15 other high-performance models, the RS e-tron GT represents a broad range of offerings. It is the result of Audi Sport GmbH’s largest model initiative to date, which was launched in 2019.

The battery protection function automatically limits the charge level to 80 percent to extend battery life. To ensure intelligent trip and charge planning, the e-tron route planner prioritizes high-performance HPC stations (High-Power Charging facilitates ultrafast charging). If the driver takes the suggested route, the system activates battery preconditioning for the period before the new Audi Q4 e-tron models reach the selected, stored charging station. If the driver selects an HPC station as the destination, the system activates thermal conditioning to ensure the battery charges as quickly as possible at the station. For the first time, the Audi Q4 e-tron model family also features post-conditioning. Here, the vehicle’s thermal management system cools the battery, for example, if it exceeds a fixed temperature threshold after driving or charging.

New drive system with higher efficiency and more power

For both rear-wheel drive and quattro all-wheel drive, all Audi Q4 e-tron models now feature a permanently excited synchronous machine (PSM) on the rear axle. 

The update gives gives the Audi Q4 e-tron model family a completely redeveloped PSM notable for its higher efficiency and greater power. The models benefit from an increased range and superior power delivery. a completely redeveloped PSM notable for its higher efficiency and greater power. The electric SUV benefits from an increased range and superior power delivery. The Audi Q4 Sportback 45 e-tron1, for example, reaches a range of up to 562 kilometers (349 mi) in the WLTP cycle.

The Audi Q4 45 e-tron2 and the Audi Q4 Sportback 45 e-tron1 with rear-wheel drive produce 210 kW (286 PS) and accelerate from zero to 100 km/h (62 mph) in 6.7 seconds. The Audi Q4 45 e-tron quattro3 and the Audi Q4 Sportback 45 e-tron quattro4 with 210 kW (286 PS) take 6.6 seconds. The top-of-the-range models Audi Q4 55 e-tron quattro5 and Audi Q4 Sportback 55 e-tron quattro6 models with 250 kW (340 PS) accelerate from a standstill to highway speed in a mere 5.4 seconds. The top speed for all models is now 180 km/h (112 mph).

The new electric motor uses optimized thermal management for greater efficiency. The system features energy-saving cooling: Due to the geometry and arrangement of the gear wheels in the transmission as well as specially shaped components for transporting and distributing the oil, temperatures in the powertrain hardly rise at all. The cooling circuit, in turn, ensures the oil is temperature-controlled. A related component is the water-cooling jacket on the outside of the stator.

Improved steering response: the suspension with Audi’s DNA

In keeping with Audi’s DNA, the new tuning for the suspension improves the balance for even greater comfort, driving fun, and stability. Whether the model has standard or sport suspension or suspension with damper control, the steering characteristics and the damper tuning have been specially adapted. The result is harmonious damping, improved steering response, and tighter load control.

With the sport suspension, the body is 15 millimeters lower. The new spring/shock absorber tuning and the new steering tuning provide a balanced, solid driving experience and a sporty steering response typical of an Audi. The Audi Q4 e-tron models respond more directly to steering changes for greater sportiness and agility. 

New function: assisted lane changes

As an option, the update enables the Audi Q4 e-tron family to use assisted lane changes in combination with adaptive cruise assist for speeds above 90 km/h (56 mph) on highways for the first time. Part of the assist package pro as well as the assist package pro and assist package, protective and warning systems plus, assisted lane changing can be activated via the MMI.

The new system uses white arrows in the instrument panel and in the augmented reality head-up display to indicate to the driver whether it is safe to change lanes and which lane it is safe to change to. If the driver initiates the lane change by tapping the turn signal, the system actively assists the driver in steering. Once the vehicle is in the new lane, it switches the turn signal off again. During the lane change, the person behind the wheel retains full responsibility. Assisted lane changes are made possible using data from the rear radar.

Among the optional systems, adaptive cruise control specializes in regulating the distance to the vehicle in front by accelerating and decelerating. Adaptive cruise assist expands the functionality of adaptive cruise control by using slight steering corrections to keep the car in the center of the lane. To maintain lateral control, all the driver needs to do is lightly touch the capacitive steering wheel that is part of the system to demonstrate their attention.

Side assist monitors traffic behind and alongside the car and warns the person behind the wheel if they are about to change lanes in a critical situation. This system also uses information from the rear radar sensors.

Critical driver assistance systems are standard, while the optional systems come with the plus, pro, and protection and warning systems plus assistance packages.

Upgraded standard equipment and edition models

Audi MMI navigation plus, Audi connect Navigation & Infotainment, and the fully digital 10.25 inch instrument panel Audi virtual cockpit are now standard equipment. The luggage compartment lid now comes as standard with an electric motor, and, in conjunction with the optional convenience key, it responds to foot gestures. Heated front seats now also come as standard.

With the new Edition S line, Audi is expanding its extensive range of individual equipment. Whether in combination with the Pebble Gray, Glacier White Metallic, or Mythos Black Metallic finishes, the wheel arch trims and door covers in contrasting Mythos Black Metallic, 21-inch wheels in a bronze matte 5-W-spoke star design, darkened Matrix LED headlights and darkened LED rear lights. At the same time, the Audi rings in a bronze finish add sporty accents.

A unique acoustic identity thanks to “character sound”

The Audi Q4 e-tron models are unmistakable – not only visually and in terms of handling but now also acoustically. With the update, Audi is giving the compact SUV series its own acoustic identity as an option. The typical “character sound” distinguishes it from other electric Audi models and those of other manufacturers. Beyond that, it deepens the emotional bond between the Audi driver and their vehicle. 

All models will be audible at and beyond low speeds up to about 25 km/h (15.5 mph) to further enhance road safety.

The digitally generated driving sound, emitted via two exterior speakers at the rear and two interior speakers in the rear doors, is available from the factory as a special feature. This innovative soundscape varies according to load and speed up to the car’s top speed. The unmistakable sound is a clear indicator of Audi’s electric models and emotively expresses the vehicle’s progressive character.

The “character sound” is defined by the exterior sound, not only by the infotainment system or the interior speakers. If necessary, the system can be deactivated at any time in the Audi drive select menu. The Acoustic Vehicle Alerting System or AVAS, which is a legally required warning sound, is part of the “character sound” and is active at all times. This does not affect the way the infotainment system sounds.

Electric pioneer Audi Brussels to produce the Q4 e-tron

From the end of the year, Audi will produce the Audi Q4 e-tron model series at its Brussels site in addition to production in Zwickau. This move, a response to the high demand for the model, allows Audi to increase production capacity. Audi Brussels has been producing the Audi Q8 e-tron and the Audi Q8 Sportback e-tron since December 2022. Prior to that, the Audi e-tron, the first fully electric production model from the brand with the four rings, has been rolling off the production line in Brussels since 2018. The plant in Brussels is the world’s first independently certified carbon-neutral high-volume production facility in the premium segment.

In the long term, Audi plans to convert all its sites to the production of electric models. After Brussels and Böllinger Höfe at the Neckarsulm site for the Audi e-tron GT quattro7, Ingolstadt will begin the ramp-up for the first model on the new Premium Platform Electric (PPE). By the end of the decade, each Audi plant will produce at least one fully electric model. As already achieved in Brussels and Győr, all Audi sites aim to achieve net carbon-neutral production1 by 2025.

The 360factory and sustainable land use

Audi is also focusing on sustainability in the further development of its sites: Audi Production is using the transition to e-mobility to comprehensively transform its global production network and has a clear vision for the production of the future with the 360factory. As part of this holistic, sustainable approach, Audi is modernizing, digitalizing, and transforming its existing plants for the future. With the 360factory, Audi can achieve even greater flexibility and efficiency in production without sealing additional areas for new buildings.

When it comes to sustainable land use, Audi is going one step further by revitalizing a former industrial site. The incampus in the south of Ingolstadt is also integrated into the company’s sustainability activities as a branch of the main plant. A joint venture between AUDI AG and the city of Ingolstadt through its holding company IFG AöR, incampus GmbH has redeveloped a 75-hectare industrial wasteland in the east of Ingolstadt. A technology park was built there – without developing any new land. Fifteen hectares of the total area were designated as a compensation area for nature and landscape; a near-natural alluvial forest with nutrient-poor grassland now thrives there.

Closely coordinated simulations and tests

More than 60 crash test dummies of various types are used in the new crash arena – from an 18-month-old toddler to an adult weighing 102 kg (225 lb). The sophisticated THOR dummies use up to 150 sensors to obtain relevant data during the tests.

High-speed cameras and motion tracking are used to capture the sequence of events during crash tests. A large number of sensors provide physical readings. 3D scans are used to process post-test deformations digitally. All this data is fed into a back-end system. The system also includes data analyzed by experts from other test labs in Europe, Asia, and America.

These days, practically all accidents can be simulated, whether they involve pedestrians or head-on and side-on collisions. Every month, the specialists at Audi perform tens of thousands of crash simulations well before the first prototype is even built. For the crash design of the body of a single current model alone, more than 60,000 calculations are made for up to 100 different load cases. The new Audi IT Center, also located nearby on the incampus site, plays an important role here.

Despite the rapid progress in simulation technology, actual crash and component tests remain essential. This is because the various national authorities in countries where Audi models are marketed have approval procedures that require physical crash tests. In product development, on the other hand, the two methods are highly synergistic, with findings from both simulation and physical testing flowing into the process.

Long tradition of passive safety at Audi

Passive safety, i.e., everything that reduces the consequences of an accident for car occupants and road users, including pedestrians, has a long tradition at Audi. DKW was already working in this field more than 80 years ago when the DKW F7 was put through systematic rollover tests to gain insights into design safety. In fact, those were the first crash tests in automotive history. Later, the specially built facility in Auto Union’s central testing department allowed reproducible collision testing.

Another major step followed in 1970 with the inauguration of the first crash hall in Ingolstadt. After its construction, the building was used for over 50 years, during which time it was repeatedly modified and adapted to meet new requirements.

In 1972, crash test dummies were used for the first time and became increasingly sophisticated and versatile over the years. In 1986, Audi introduced a self-patented innovation: the procon-ten (programmed contraction and tension) safety restraint system. In a head-on collision, the steering wheel retracts, and the front belts tighten by moving the engine toward the passenger compartment via steel cables and pulleys. The system significantly reduced the risk of head injuries for the driver in the event of an accident. It was not until the widespread introduction of airbags that this invention was improved on.
