New Audi A4 1.9 TDI e: 45 MPG and 137 g CO2/km

2 May 2007

A4tdie
The A4 TDI e.

Audi is extending its highest-volume model series, the Audi A4, with two new models based on its 1.9 TDI e engine.

With an output of 115 hp (86 kW), the A4 1.9 TDI e, available as a sedan and as an Avant model, consumes 5.2 l/100km (45 mpg US) and emits 137 g CO2/km. The A4 accelerates to 100 km/h in 11.2 seconds and has a maximum speed of 201 km/h (125 mph).

The A4 furthermore has high transmission ratios for gears 3 to 6, which contribute to lower fuel consumption. The engine electronics are engineered for economy. Various weight-reduction measures, including an aluminium hood and low-rolling-resistance tires in size 205/55 R16, in addition to aerodynamic features such as the saloon’s integrated S line rear spoiler contribute to the overall efficiency of the package.

Audi had earlier introduced a 105 hp (78 kW) 1.9 TDI e application for the A3, with combined fuel consumption of 4.5 l/100km (52 mpg US) and with CO2 emissions below 120 g/km.

I'm assuming this isn't available in the U.S. Is that correct? I'm still looking for an AWD that gets over 40 mpg. Maybe they will bring the Prius AWD from Japan to the U.S.

They have a Prius AWD in Japan??? They slipped that one by me, I'll have to google that

Audis are awesome cars. Will this be available in the US?

It's nice to see a luxury maker get closer to 50MPG with traditional engines/luxury and AWD! Wow!

They don't seem to offer any TDIs in the US :(

I don't know how many of Audi's core customers, in the US, would purchase this vehicle. I'm sure it could easily get 5% of the Audi A4 purchases but there is a reason that they have been bumping up the horsepower and engine sizes year after year on the A4: That is what the customers demand.

Tier2 Bin5 version for an A3 3 or 5 door hatchback would be my choice.

VW intends to re-introduce the TDI to the U.S. for the 2008 MY.

They don't really say in the article, but since Audi and VW are essentially one company, it stands to resaon that it wouldn't be hard for them to adapt the VW engine with emissions controls into an Audi body. For all I know, this is exactly what they are announcing today...

I don't think this one is AWD.

But it has decent performance and fantastic economy for a decent sized car, so well done.

@ mahonj -

correct, its FWD. For reference, the regular A4 1.9 TDI requires 5.7L/100km in the same NEDC drive cycle, i.e. this new TDI e version is 9% more economical.

In addition to the the diesel, there's also a A4 2.0 TFSI e. Relative to the standard model, rated power has been cut from 200 to 170hp, but fuel consumption on Euro98 has gone down from 8.0 to 7.1L/100km (an 11% improvement).

There are also economy variants of the A3. According to Audi's press release, the economy boost was achieved through a combination of the following factors:

- engine controller tuned for fuel economy
- longer ratios for gears 3 through 5 (Audi A3 only)
- long ratio for gear 6 (already standard on A4)
- weight reductions, e.g. aluminum bonnet
- low-resistance tires 205/55 R16
- aerodynamic improvements, e.g. spoiler from S model

It is starting to sound like the 80's when most small cars in the US had a de-contented/driveline tweaked model to boost the MPG numbers.

I definitely would by the A4 TDI, especially if it used the Blueline tech. Bring it to the US!

I would like a Passat wagon with a TDI engine!

LiveGreen - here is your wagon! http://seattle.craigslist.org/see/car/323557764.html

My partner has an old 1997 Audi A6 2.5TDi (140bhp) and for it's size and displacement gets excellent fuel economy (40 mpg US combined average). This is helped by the fact it has a 6-speed gearbox, so that cruising at 70 the engine speed is only around 2,000 rpm. Not only do diesels get excellent fuel economy, they also get higher milages compared to petrol engines. Remapping the ECU could improve power (+30bhp)and economy (by up to 20%), which we are seriously considering.

I'm definitely a German car fan, although I couldn't afford a new A4. I think a Passat TDi to replace my current 1.8T (Petrol) will be worthwhile in a few years. It will be worthwhile too since petrol costs $7 per US Gallon in the UK. Much better than choosing an econobox.

Thanks skldrd But for 29K!! Whoa! I was hoping for a 2008 TDI Passat Wagon.

America gets a Q7 TDI SUV lux-tank. Why not an A4 Avant that gets 40+ mpg instead? I'm switching to BMW...

There are developments in DME in China:
We see great potential for DME as a clean alternative fuel . The present diesel oil is a major source of air pollution from diesel engine of trucks and busses in large city like Tokyo. The potential market of diesel oil substitute is larger than LPG. DME is one of ideal fuel for diesel engine. DME vehicles were demonstratively manufactured in Japan, China and Korea and their driving test already started. Practical durability fleet test of a DME truck is under going in Japan.

We are pleased to organise a conference on China taking the lead in the DME market in production from coal and Japan and Korea activities.

If you would like to know more on COAL to Syngas to DME developments, join us at upcoming North Asia DME / Methanol conference in Beijing, 27-28 June 2007, St Regis Hotel. The conference covers key areas which include:


DME productivity can be much higher especially if
country energy policies makes an effort comparable to
that invested in increasing supply.
By:
National Development Reform Commission NDRC
Ministry of Energy for Mongolia

Production of DME/ Methanol through biomass
gasification could potentially be commercialized
By:
Shandong University completed Pilot plant in Jinan and
will be sharing their experience.

Advances in conversion technologies are readily
available and offer exciting potential of DME as a
chemical feedstock
By: Kogas, Lurgi and Haldor Topsoe

Available project finance supports the investments
that DME/ Methanol can play a large energy supply role
By: International Finance Corporation

I think the technology behind these clean turbo diesels are great...I had a prius and it was an inferior car inside and out.
Buy an Audi - You get a lot more for your money
