Audi R8 V12 TDI Concept

Before images from the Detriot Motor Show start pouring in, we thought we’d go over some of the cars expected to make their début in a little more detail. Apart from the new sports TTS, Audi is presenting the ultimate road going diesel car. The R8 V12 TDI Concept.
Using a newly developed twin-turbo 6.0-litre 12-cylinder diesel engine, the V12 TDI is based on the standard Audi R8 but proves the point that diesel doesn’t always mean slow. With 373kW and 1,000 Nm of torque this supercar goes from 0-100 km/h in just 4.2 seconds.
Using two turbochargers (which generate up to 2.6 bar of boost pressure), peak torque is not only enormous but also effortless, coming on at just 1,750 rpm to 3,000 rpm. As for the 368 kW, the diesel achieves a specific output of 62.0 kW per litre displacement.
The actual engine design is relatively similar to other turbo diesels from Audi. Two large intercoolers are used to reduce the temperature of the compressed air, connected to a twin-pipe exhaust system with two particulate filters.
If you’re still of the school of though that diesels are dirty, it’s time to wake up. This Audi R8 V12 TDI concept can already fulfill the Euro 6 emissions standard while most supercars struggle to meet Euro 5.
Audi has ensured this V12 doesn’t sound like a truck, the company says the engine is full-bodied and equipped with energetic overtones to guarantee an exciting sound.
The V12 TDI marks yet another milestone in diesel technology, and it’s no wonder that Audi is behind it. The German luxury brand has been experimenting with diesel engines for decades. Some of the company’s milestones include:
- 1978 - World’s first five-cylinder diesel engine in the Audi 100.
- 1989 - The first TDI auto engine made.
- 1994 - the first TDI quattro model.
- 1999 - the first eight-cylinder TDI – a V8 engine with a 3.3 litre capacity.
- 2004 - The 3.0 TDI made its debut as the first V6 diesel with inline piezo injectors in the common rail system.
There is no official word from Audi to suggest the V12 TDI will make it to full-scale production, but given the popularity of diesel engines in Europe, it is likely.

This is more than a statement of intent - it will happen.
Other car makers can now only imitate.

Lcat,
I only hope that you’re right… I would have no hesitation in purchasing this diesel monster (given the funds of course…!)

What a brilliant machine. The one thing that i’d prefer in the petrol one, is the crazy sounding, high reving 4.2L. V8. Gotta be heard to be believed. I thing the aural pleasures associated with high revs adds o the supercar experience.

Aren’t diesels dirtier in terms of more poisonous gases but produce much less CO2? The Euro standards only look at CO2 am I right?

I know this might seem a really really dumb question but I wonder what MPG it gets.
If it looks that good and goes so hard if it was cheap to run it would be quite a car that I will probably never afford.
Ford and Holden a diesel can be quick. Ford have put truck motors into a cars before.

Bob your right on there. Diesels produce more NOX than a comparable petrol engine but about 20-30% less Co2. The NOX is a bigger problem than Co2 but I read somewhere that as the diesel engines gets more miles under its belt the NOX tails off to less than a petrol equivalent. I’m no chemist but NOX is Nitrogen Oxide and accountable for people with lung diseases, asthma etc. When NOX and VOC’s (volatile organic compounds) react in sunlight they produce smog basically.
Mmmmmm perhaps we should consider the hybrid thing more.
