It has recently dawned on me that no one seems to have a diesel car on this site or keeps quite about it,is there a lot of audi diesels in states as in UK and Europe most Audi a4 or a6 are the 1.9 tdi models.

not me ,not me 1.8t

 

there aren't any diesel Audis in the states that i'm aware of

 

All the big german car companys probably sell more diesel than petrol in europe.

 

that's because of your crazy high gas prices...if i was paying 8 bucks a gallon i'd have a diesel too...as a matter of fact, even with our prices at 3 bucks a gallon i'd consider getting a diesel a4

 

Well most a4 diesels can be had with 150bhp tdi giving loads more torque than petrol models.Raced a golf gttdi once and only left him once we got over 95 mph.Its just that they sound **** and smell ****.

 

I had an A3 1.9 tdi (130, chipped to 160) in the UK. It was fantastic. If they had them here I would have the 1.9 tdi over the 1.8 T anyday. The power is incredible, from such a tiny wee engine. In the A3, which was fwd, you could wheelspin in 4th with the traction control off. They also had the 2.5 which you could chip to 200 hp, and silly amount of torque. I've also driven the 330D and it is VERY rapid. Overtaking is a breeze, as as soon as you put the foot down, off you go... Diesels are great engines, and they don't sound as crap as they used to. I had a magnex exhaust and it sounded fab.

 

blurred as a new Audi A8 TDI luxury saloon claims the title of the world’s most powerful production diesel. The new 326PS Audi A8 4.2 V8 TDI quattro will be available in standard and long wheel base body styles costing £58,605 OTR and £61,975 OTR respectively, and will set a new benchmark for TDI performance while actually also reducing fuel consumption compared with its predecessor.

15kg lighter than the 4.0-litre eight-cylinder TDI it replaces, the compact new 4.2-litre unit is the first Audi V8 TDI engine to incorporate the latest common rail fuel injection system with state-of-the-art Piezo injectors. The precisely metered fuel delivery that Piezo technology makes possible ensures that the new twin-turbocharged and twin-intercooled engine not only provides more power and even stronger performance than the 4.0 TDI, but also holds a fuel economy advantage.

Power has risen by 51PS from 275PS at 3,750rpm to 326PS at 3,750rpm. Peak torque of 650Nm is also available 200rpm earlier, from 1,600rpm, and remains constant for an additional 1,000rpm, right up to 3,500rpm, making for truly remarkable response.

A body shell that is over 40 per cent lighter than the norm thanks to aluminium construction around the aluminium Audi Space Frame (ASF) allows full exploitation of the exceptional output. Rapid-fire gear-changes from the six-speed tiptronic automatic transmission, and secure all-weather power delivery via the quattro four-wheel-drive system, also help the A8 4.2 TDI quattro to power to 62mph from rest in just 5.9 seconds, and to ride a wave of torque right up to an electronically governed 155mph.

Despite the major power and performance gains, the combined fuel economy figure for the new A8 4.2 TDI quattro actually shows a slight improvement over its predecessor at 30.0mpg (A8 4.0 TDI 29.4mpg), thanks in part to the advanced Piezo technology. This equates to a potential range of up to 590 miles on a single tank of diesel.

Featuring a separate high-pressure pump and rail for each row of four cylinders, the Piezo system permits up to five separate amounts of fuel to be injected on each working stroke at an injection pressure of 1600 bar, 250 bar more than with previous common rail systems. This helps to achieve the best possible fuel/air mixture and an even more efficient combustion process.

Environmental impact is also minimised by a diesel particulate filter, which is fitted as standard and works in conjunction with the twin catalytic converters to maximise exhaust gas cleansing. The system needs no additives, and so will need no servicing throughout the lifespan of the car.

In common with the rest of the range, the new A8 4.2 TDI quattro will feature the latest Audi corporate look characterised by the distinctive single frame grille. It will offer adaptive air suspension for optimum ride comfort, controlled via the acclaimed Multi Media Interface (MMI) in-car control system. An upgraded SE equipment specification has also recently become a standard feature of V6 and V8 models, and there is now the option to add a new Sport pack available at extra cost.


now thats power

 

i'll take two please.

 

Diesels are now selling neck on neck with petrol in Africa. Main reason is the price factor of petrol. I did some research and diesel is only more cost effective over a few years period. One must also take into account higher running costs. The new generation diesel engins are great these days with massive torgue.....but I still prefer petrol. The 2.0 FSI engine is a dream

 

I have a A4 1,9 Tdi (130Hp)
I drive mostly on highways and love the grunt and mid-speed acceleration (60-120 km/h).
I just tried a 1,8T (petrol), and it felt weak compared to the diesel, same with the 2.0NA engine, and the 2.8.

I get the economy AND the (useful) power. My next car will definately also be a diesel.
