BMW 320d EfficientDynamics – Click above for high-res image gallery

British auto journalist Tom Ford recently decided to test BMW's claim that its new 320d EfficientDynamics model could achieve 1,000 miles on one tank of diesel fuel. While the EfficientDynamics is the most efficient version of the 3 Series available right now, it is not the lowest power version. With 163 horsepower and 280 pound-feet of torque, the 320d can get from 0-62 miles per hour in just 8.0 seconds. The incorporation of electric power steering, a lower ride height and automatic start-stop helps the 320d ED achieve a 57.4 miles per gallon (U.S.) on the EU drive cycle.

Ford decided to drive from England to Munich and back to see how many miles he could squeeze out of a single tank. To extend the drive, Ford kept the windows up and the air conditioning turned off, but otherwise drove about 65-70 mph on the motorways and autobahns. By the time the tank ran dry, Ford had covered 1,013 miles and got to within 70 miles of Calais on the return route. That's an average of 57.4 mpg at 59.3 mph, numbers we could certainly live with. You can check out Ford's video report at the Sunday Times Facebook page.

The 1,000-mile BMW

* 24.05.2010
* Press Release

BMW's cleanest and greenest 3 Series ever has just completed a record-breaking journey from the UK to Munich and back - on one tank of fuel.

Filled up at the Channel Tunnel, the new BMW 320d EfficientDynamics Saloon made it to Munich, then as far as Lille on the return leg – a staggering total of 1,013 miles on a single tank of fuel – before needing to be refuelled.

To put it in a UK geographic context, the distance achieved would have meant being able to drive from Land's End to John O'Groats, and still having 200 miles range left in the tank.

Just as impressive was that the intrepid driver - motoring journalist and TV presenter Tom Ford - didn't use efficient driving techniques such as coasting, or drive deliberately slowly for the trip, coverage of which appeared in yesterday's Sunday Times newspaper.

Although switching the air con and radio off as a concession to fuel saving, Tom managed a reasonable motorway pace all the way there and back, proving that in the real world, the new BMW 320d EfficientDynamics Saloon delivers what its promises on paper – an official combined figure of 68.9mpg and CO2 emissions of only 109g/km.

On the way to Munich, Tom achieved highs of 75.9mpg, and didn't dip below 65mpg for the entire trip. With an average speed of 59.3mph, the car achieved 68.9mpg overall.

He said: "I was prepared for this car to fail in the real world. I was wrong.Although I did try and be careful and drive in a feather-footed manner, I did cruise at a reasonable 65ish mph on the autoroutes and autobahns, so faster than the usual economy run pace.

"Think about it in the context of everyday motoring: comfortably more than 1,000 miles on one tank of diesel means just 12 fills a year for the average motorist - and even driven normally I still think you're looking at 750-800 miles per fill. BMW's EfficientDynamics: it does what it says on the tin."

The BMW 320d EfficientDynamics Saloon develops 163hp between 3,500rpm to 4,200rpm and 360Nm of torque from 1,750rpm to 3,000rpm. This equates to a zero to 62mph time of 8.2 seconds and a top speed of 137mph ensuring that while it might be extremely efficient, it still offers sporting performance - a fact not lost on Tom.

He said: "It's difficult to tell the difference between this model and a standard 320d in terms of driving performance which is brilliant. It means that as well as the obvious financial advantages, this special 320d is a car for the environmentally conscious who still want a car that drives superbly."

For drivers choosing the BMW 320d EfficientDynamics Saloon, there is no VED to pay for the first year of purchase due to its low CO2 figure and a 13 per cent benefit-in-kind company car tax rating and sporting ability thanks to its 163bhp. For a business buying one, the sub 110g/km emissions mean 100 per cent first year writing down allowances, allowing the model's full first year depreciation against to be offset against Corporation Tax.

The BMW 320d EfficientDynamics Saloon comes with the existing suite of BMW EfficientDynamics technologies, including Auto Start-Stop, Brake Energy Regeneration and Electric Power Steering for optimum performance. However it also achieves its class-leading emissions with the addition of innovative engine construction, a longer transmission ratio, lowered suspension and the use of specially designed aerodynamic alloy wheels with Michelin EnergySaver tyres.

      BMW has a hybrid that does 50g/km CO2. It has an electric motor for the front axle and the rear axle is powered by either a second electric motor or a turbo diesel. Technically that's a parallel hybrid but look at the link and I think you'll forgive me for wanting BMW to make them.

      "BMW's "CO2 Champion" Performance Concept is a Plug-in Diesel Hybrid; 50 km/31 mile All-Electric Range; Thermo-electric Generator for Waste Heat Recovery"

      This is one parallel hybrid I could get behind.

      I always thought that miles per tank was an odd thing to care about, all a manufacturer has to do is put in a bigger tank to increase this number.

      A semi truck with dual 100 gal tanks getting 5 mpg goes 1000 miles on a fillup.

      Thats good mileage, but this is on the highway where diesels excel but with an average speed of only 59.3 mph. I bet a prius driven on the same route at the same speed would get better mileage and it would get much better mileage than the bmw on an urban driving test.

        "This equates to a zero to 62mph time of 8.2 seconds and a top speed of 137mph ensuring that while it might be extremely efficient, it still offers sporting performance"

        Apples to oranges. Of course you can always choose a slower car which also has its handling sacrificed to fuel mileage and do a little better. There are also smaller cars displayed almost weekly in this blog that are more efficient than the Prius.
        • 5 Years Ago
        I'll name one, the Vw Polo TDI Bluemotion Model. It is significantly more efficient than the Prius even on the EU Cycle. I'm sure it would beat the Prius in EPA as well.

        wincros: "There are also smaller cars displayed almost weekly in this blog that are more efficient than the Prius."

        Really? Then name one!
        • 5 Years Ago
        wincros: exactly.

        A prius is going to be 1/3rd of the fun to drive as this car. Have you ever driven a BMW?
      • 5 Years Ago
      My perfect garage would be this and a Nissan LEAF.

      I cannot believe BMW only gave the US the I-6 diesel engine...
        • 5 Years Ago
        uh huh.... we don't have this... WHY?

        0-60 in 8 seconds is not too bad for a luxury car. Faster than an economy car and boudless torque, which is the main problem of an economy car going up hills, etc.

        BMW USA, please pull your collective heads out of your arses.
        • 5 Years Ago
        I would love to see this in Touring form talk about an all out perfect car! Excellent mpg, still fun as hell to drive (its a bmw after all) and with the wagon version you would still be able to haul all your gear for weekend adventures!
      • 5 Years Ago
      This obviously plays to the advantage of diesels. It has higher energy density so all things being equal, a diesel will travel further on tank. Also, diesels do better on the highway.
      • 5 Years Ago
      Are those UK mpg numbers? Cruising at 105 km/h is not real world especially in Germany.... I don't think it's safe to drive that slow in several parts of German autobahn most of the time and that's 25% slower than recommended speed in Germany.

      So to summarize: $10K more expensive than Prius with slightly worse combined mpg rating and 20% more CO2. What's so special about that?

      For some reason Toyota/Honda don't do these tests (probably because what's the point).
        • 5 Years Ago
        'So to summarize: $10K more expensive than Prius with slightly worse combined mpg rating and 20% more CO2. What's so special about that? '

        Significantly lower VOC emissions, carbon neutral % if run on bioD, and most importantly, it's a BMW. The interior quality of my Prius is garbage compared to this car. The overall build and parts quality of a Prius is about what I'd expect from Corolla, and isn't anywhere near the league of this BMW. I drive a Prius for the MPG, not because it's a nice car.

        Not to mention that driving a German car has a fun factor that's incomparable to the sterile utility of a Prius.

      I was driving my accord Diesel today on the Motorway wafting along at 60 mph at just under 2000 rpm getting just over 50 mpg us. Very quiet and certainly not stinky !
      Everyone was passing me of course !

      Not sure how you would do 1000 miles in an electric at least not all in one go or on one tank as you would have to stop what about ten times ? and in many areas electricity isnt generated from clean sources, although overall pollution would be less.

      I dont understand why some people are so critical of a car of this power and performance that is so economical - many of you are saying how incredible it is that a Fiesta can get 40 mpg us and this Bmw does 55 mpg us. So you could have a much slower Prius or tdi golf or Focus in Europe anyway. They are all cheaper by about £5000 mind you !

      About the only thing in common between a Prius and this BMW are that they each have four wheels and are called cars ! BMW comes with a six speed manual like my Accord.
      • 5 Years Ago
      I don't think the 2 cars are comparable, Paul. Those figures are pretty compelling. Obviously the BMW is more expensive and has a larger fuel tank. Their claim has been verified (just barely). The German diesels are pushing Toyota's high mileage dominance pretty hard here, and I expect Toyota to respond with the next round of technical advancements to the benefit of us all. The market works. Competition benefits all. Next I expect BMW to add an efficient hybrid system to their beautiful turbo diesels to end the Prius' dominance once and for all.

      BMW offers a NOx-reducing catalytic converter, just like the one in the American-spec Golf/Jetta TDI, as a €1000 option on European 320d, 520d, 330d and 530d models. That option brings them from Euro 5 emission levels to exceeding the 2015 Euro 6 standards. I bet, eqipped like that, it wouldn't be a problem to export it to America.
      With the NOx cat, the 320d ED is still 1000€ cheaper than a 328i...

      Of course BMW NA's marketing department reckons four-cylinders would be bad for the brand. Yeah right.

      "So how did you get 128lbs of diesel to make 384lbs of CO2?"

      Trace, brush up on your high school chemistry. The C in CO2 comes from the fuel, the O2 comes from the air intake.

      • 5 Years Ago
      So how does the environment fare after that 1000 mile trip in your gas burner?

      1000 miles = ~1600 km @109 g/km = 174,400 grams of CO2 = 384 pounds!

      No thanks. I'll stick to my electric vehicle getting green power from Texas wind!
      - - - - - - - - - - - - - - - - - - - - - - -
      Now for some better news: Texas has already reached it's 2025 renewable energy goal!

      "Texas has reached its goal of having 10,000 megawatts of renewable energy capacity this year, 15 years earlier than scheduled, thanks to an ample supply of West Texas wind."

        Trace "So how did you get 128lbs of diesel to make 384lbs of CO2?"

        Carbon from the fuel combines with oxygen from the atmosphere. One of the dirty secrets of diesel is that there is a not more carbon in it per gallon than gas, so a gallon diesel produces a lot more C02 even well to wheel.

      I already expected for a long time that real life EV's would soon be able to do 1000 miles on one charge :-)
