The Audi R8 Project – The Best Used Supercar?

We recently purchased a gen 1 Audi R8 to use as our 2020/21 project car. We aim to test out this used car, clean it up, modernise it and write about it over time. We will be building the ultimate guide to Audi R8 ownership during our testing.

Audi R8 Project Intro

I have always felt that the R8 has been a massively underappreciated car. This was mostly due to the R8 not having a long line of predecessors like its competition the Porsche 911 or the baby Lamborghini.

The R8 (Type 42) began production in 2007, just about 8 years after Lamborghini became a part of the Audi family and the R8 shared a lot of components with the much more exotic Lamborghini Gallardo which happens to be one of the best selling supercars ever. Nevertheless, the Audi R8 is a car that deserves some love and that is what we plan to do with this project.

Project Car Details

The Audi R8 that we will be focussing our attention on is a generation one version with a 4.2-litre FSI V8 engine and a manual gearbox. It has an aluminium spaceframe construction and an all-wheel-drive system.

However, what separates the R8 from the rest of the supercar world are the carbon fibre “sideblades”. It gives the car an aggressive look and makes it appear larger than it really is. It was marketed as the everyday supercar and that is reflected on the inside with great head and shoulder room for two people and the frunk where there is just about enough room for a few bags. It also had one of the friendliest price tags among the two-seater supercars of the time.

Plan – Clean Up and Modernise

With the car being second hand, the first step involves cleaning the car and correcting most of the minor cosmetic flaws. Then we will look at making this car in tune with the times by modernising a few things. At its heart, it is still an excellent car and the addition of a few things should make it a great fit even on current roads more than a decade later.

The Downside

Like with buying any used car, there are certain risks involved. This is especially true here when it comes to a performance car like the R8. The most common risks include the following issues.

  • Magnetic ride: The R8 is equipped with magnetic ride suspension which for a car of its time is pretty advanced but it comes with its set of problems. Over time these struts leak and will need to be replaced, they are very costly. Our project car has already been swapped over to BC Racing coilovers. So this problem is not going to occur thankfully.
  • The clutch has to handle a lot of stress from the powerful engine and that can cause a lot of wear and tear over the years. Again our test model has had a recent clutch and flywheel. So that shouldn’t be an issue.
  • Like most used cars the air conditioning unit has plenty of chance of failure as it ages. However, it is placed underneath the engine in an R8. Meaning it is difficult to fix. Ours has already been replaced.

There are other things that one needs to look for when buying an old R8 which we will discuss in detail in our buying guide soon.

Initial Upgrades Planned

To make it all worth the effort, just doing regular maintenance won’t be enough and a few modifications are needed to really spice up this car and inject a new lease of life into it.

One of them would be to set up the coilovers so that the suspension is properly stable. It will also make the car quite capable around a track while allowing it to retain its real-world practicality. There are other benefits too which we will discuss in detail when we do the work. The brand we have fitted is BC Racing as it is relatively simple to install, is priced reasonably and above all, improves the handling, comfort, and the performance of the car by a fair margin.

Detailed Car Review

How does the generation Audi R8 drive? What is it missing? Is it still relevant today?

I am a firm believer in the thought that a supercar isn’t about the numbers or anything physical on it. The best supercars manage to bring a smile on your face no matter how unconventional or flawed they are and because the Audi R8 is the epitome of this definition, it is a car I highly recommend. The one downside of the R8 compared to its more established supercar competitors is that it really lacks a loud and fiery exhaust note. Find out more…

We take the Furniture Clinic Leather Clean & Protect to the leather seats of the Audi R8 and see if it is something you should buy for restoring your own leather seats. Find out more…

Continental ContiSportContact 5 P R01 Tyres

I found these tyres especially appealing as they had been specifically made for the Audi R8 when the car was new. It is like a bespoke suit. Audi and Continental worked together to develop this tyre specifically for the R8.

We replaced our worn tyres with a fresh set of ContiSportContact 5 P rubber and the results spoke for themselves.

One of the defining characteristics of any tyre is the dry grip. Thankfully, these tyres did not let me down. I was able to make a clean getaway and the tyres instantly improved the way the R8 behaved on a dry road.

In the wet the clever tread design does work as they can clear enough water to keep the tyres stuck to the tarmac. Wet weather braking was way better than I expected as the car was still able to stop from reasonably high-speeds in a controlled manner, without fish-tailing or simply aquaplaning. I would not recommend these for a spirited drive on the track in pouring rain but you can easily drive at normal speeds even when there is standing water on the road.

The upgrade makes the R8 better equipped while retaining enough of its practicality to make it an easy car to live with on a daily basis. These tyres are ideal because they were purpose-built for the Audi R8 and just as any suit aficionado will be able to attest to, if given the choice, you should always go for the tailor-made option rather than something generic.

Topgear Audi R8 V8 Valvetronic F1 Exhaust

Driving the R8 V8, you soon realise that the missing link was its sound. It did have that V8 burble going for it but the noise was rather muted and almost lifeless. I wanted something that made a noticeable difference to the exhaust note without breaking the bank (relative to the cost of the car) and more importantly, I needed something that didn’t sound noisy all the time.

Topgear Exhaust

I still wanted it to be quiet when I need it to be. The Topgear Audi R8 V8 Valvetronic F1 Cat Back Performance exhaust seemed to fit the bill perfectly, so I decided to give it a try. Read the full review here.

M-Tech Audi R8 Custom Piston Gear Knob Replacement For R8

The gear knob in these cars really shows its age and every time I grabbed it for a gear shift, it just didn’t feel like something inside a modern-day sports car. As such, I opted to replace it with something that looked and felt cooler and upped the ante inside the R8. I went for this M-TECH custom made‌ gear knob. Find out more…

Upgrading The Head Unit – Eonon GA2178

We decided on a floating screen because once you remove the original head unit and control buttons below, simply fitting a double din unit does look a little plain. We went for the Android Eonon GA2178 unit. See the full installation here. So we chose the Eonon GA2178 that came with a dashcam, rearview cam and OBD dongle. In short, it worked out really well. The large screen looks premium and has a good resolution. It also allows you to use Apple CarPlay and Android Auto, with the addition of the USB dongle, which is perfect!

Replacement Mats – Exclusive 1200gpsm – Carmats4u

I wanted to upgrade the car mats to something a bit more suited to the R8. The replacement had to be of superb quality while being fresh enough to make the inside of the R8 come alive. I am quite happy with the car mats I got for the R8. It fits the car perfectly and the inside of the Audi now looks and feels so much more refined. Costing just under £50, these floor mats from carmats4u.com gets my vote of approval. Find out more…

Maintenance

So far these are the different maintenance steps we have taken on the car to keep it in top performance.

Replacing The Original Battery

The Audi was still running the original OEM battery from 2007. It starts well, but a 13-year-old plus battery isn’t going to be as reliable as a new one. If you want to know the age of your Varta battery the week number and year is stamped on the negative terminal.

We chose to replace the battery with a Yuasa 110Ah full-size battery with 950 cranking amps of power. The battery costs around £130 and comes with a 4-year warranty, this wasn’t needed straight away, but is great maintenance when you want a reliable car and should assist with the additional power requirements of the new head unit.

Replacing The Spark Plugs

Looking at the cars service history it had only done around 7,000 miles in the last 5 years. To keep the car firing on all cylinders we made the decision to look at replacing the half-decade old spark plugs with some shiny new ones.

We went with the NGK Laser Platinum spark plugs. Replacing the plugs means pulling all eight coils and using a 16mm socket to remove the spark plugs. You can see below that even with just 7,000 miles of use they still have heavy deposits on. The plugs cost around £120 for eight and a great maintenance part for the car.

Fuel System Cleaner – Redex

The fuel system in the R8 is made up of a fuel tank, lines, filter, one low pressure fuel pump and two high-pressure fuel pumps and 8 injectors. Redex cleans the fuel system and gets rid of all the deposits that build up over time. Deposits, in turn, can make the car feel sluggish especially when you try to pull away or when trying to accelerate hard.

On a more serious level, it can reduce the fuel efficiency of your car and increase emissions as well. We tested out Redex Advanced Petrol Cleaner. See what we found out here.

Paint Repair – Touching Up With Chipex

Any car that has been on the road for a few years will pick up stone chips. To a car guy, you get a bad feeling inside when you see a new stone chip on your pride and joy. However, it is part and parcel of car ownership.

The R8 over the years has picked up a few stone chips here and there, but particularly on the back of the R8 there was a strange mark in the paint I was keen to cover up.  I did some research and decided to use Chipex to touch up the paintwork. I have used it in the past on other cars and the results have been good.

The process is fairly simple, clean down the area, apply the paint, smudge with your finger, allow to dry, then gently blend in with the provided solution. After that, allow some more time to dry and polish up the area for maximum effect.

Silver is a difficult colour to touch up, but Chipex gets as good as you can without sending it off for expensive paint repair. The mark is a lot less of an eye saw and I can live with this now, whereas before I was very keen to get it repaired asap.

Best Charger Audi R8 Battery

The Audi R8 has a very large battery. It is rated at 110Ah. The Amp Hour (AH) specification provides a measurement of battery capacity. It is an indication of how much energy can be stored by the battery. So if you haven’t used the car in a while and want to charge the battery you will need a decent charger.

A powerful charger such as the CTEK Pro Battery Charger MXS 10 will be able to charge the battery at a maximum rate of 10 amps per hour on a charge. So would take around 11 hours to fully charge the car from flat. You might find most of the chargers available to buy are a lot less powerful around 4-5 amps per hour which could take around 20 hours or longer to charge the battery.

We tested out the CTEK Pro Battery Charger MXS 10 on the R8 and has some nice features like the quick connect adapter for regular trickle charging without the clamps. Find out more here…

Misfire P0300 Fix – High Pressure Fuel Pump Issue

Shortly after buying the Audi R8 V8 the car developed a performance fault, when pushing the car to full-throttle, the R8 would stutter or misfire between 4,000-5,500 rpm.

This started off as being intermittent, but after a while began to occur every time passing 4,000 rpm. The fault showing on the ECU most frequently was “P0300 – Random/Multiple Cylinder Misfire Detected”… Read about the fix here.

Servicing in UK

This is another area where a lot of doubts can arise and it can get quite confusing. Buying a used car without a hassle-free servicing option can be a big headache even if you get the best car in the world. Thankfully, Audi has a good servicing network in the UK and most of them are equipped to take care of an Audi R8.

As for the actual schedule itself, the servicing comes in two forms – a fixed servicing option that takes place every 9,300 miles or 1 year.

Another thing to keep in mind when buying a used car is the servicing history of the car. Preferably, it should have been serviced by an authorised service centre while strictly following the service schedule. A sports car is a high-performance machine and it requires slightly more care than a regular car and that is why a good service history is critical.

Oil Change and Inspection – £ 520

We had the car serviced for the first time. The car is at 65,000 miles and 13 years old. The car was due an inspection and oil change. Which makes it the bigger service of the two servicing options. The R8 also required a brake fluid change which needs to be done every two years.

We chose to use an Audi Specialist based in Birmingham for servicing. Compared to using the Audi main dealer, an independent specialist garage is the better option with a car at this age. They use all genuine Audi parts, but the labour is more cost-effective.

Below is a breakdown of the servicing costs including taxes.

  • Oil Change and Inspection – £ 520
  • Brake Fluid Change – £79

During the brake fluid bleeding process it was picked up that both the rear brake caliper bleed nipples were blocked so they needed to be replaced. The cost around £8 each.

Overall the servicing costs of the R8 V8 manual aren’t too bad, if you compare it to an RS3 as an example you would be paying an additional cost for servicing the Haldex units and DSG transmissions etc.

For reference see the breakdown of costs pre-VAT (20% UK) below.

Running Costs

Here is a simplified breakdown of what the car is costing to run so far in 2020.

Yearly Costs

  • Insurance: £800 (including modifications)
  • Road Tax: £570
  • MOT: £35
  • Servicing: £600

Ongoing Costs

  • Fuel: £100 for a full tank of Shell V-Power (300 mile range)
  • Oil Top Up: 1 litre – £15 (Needed every 2,000-3,000 miles)

Replacement Parts 

  • Battery: £140
  • Spark Plugs: £120
  • Wheel Alignment: £120

Keeping Within The Speed Limits – Road Angel Pure

With a performance car like this, it is very easy to find yourself soon well over the speed limits and in trouble with the law.

We have started testing the Road Angel Pure. It is a speed awareness product that knows the speed limits on all roads and even has built in laser detection.

After even a short time testing this product it is working out to be a great companion for the R8 giving you the alerts you need to stay on the right side of the law, but still, have fun in the car. Find out more…

R8 Competition = 911 / V8 Vantage / 458 /Gallardo

As we alluded to earlier, the Audi R8 has a lot of competition. The most obvious one for the gen 1 version is the Porche 911 from the same timeframe. You can get a used 911 for a similar price and the two are evenly matched when it comes to the performance. The R8 is better looking with the 911 being a bit more feature-rich and practical. But I do think the R8 has dated better with time.

Other cars like the Jaguar XKR and Aston Martin V8 Vantage can also be bought at similar price points. Both are a lot more comfortable but come up short on the performance side of things. If performance is the sole criteria then the R8 is better matched against cars like the Lamborghini Gallardo or the Ferrari 458 but both go for up to double or triple the price of a used R8 and spending that much on a used car does not make a lot of sense for a project like this. The Audi R8 offers the best of all worlds and that is why it is the car of choice here. Lets not forget that Audi did also offer the V10 version of the R8 which has more performance, but is also more costly to buy and run.

    Hi all, I’m very interested in the R8 article. I’m also glad it’s the standard V8 Version as I feel this has the best balance of performance, value, and engine note. Very glad I tuned into this site. Many thanks!
