BMW Advanced Diesels – excellent performance, decent fuel economy and US emissions compliance all in one beautiful package. [xfloat=right]http://www.cleanmpg.com/photos/data/506/BMW_330d.jpg[/xfloat]Wayne Gerdes – CleanMPG – Jan 2, 2008 The 2008 North American International Auto Show (NAIAS) in Detroit will host 2 BMW diesel previews. Both the 335d Sedan and X5D SUV equipped with BMW’s advanced 3.0L diesel and 50-state compliant Blue-Performance emissions system will be shown with scheduled availability in late fall of 08 as 09 models. The BMW 335d’s advanced diesel is rated at 265 hp and 425 lb-ft. of torque at just 1,750 rpm with a 0 to 60 time of approximately 6.0 seconds. Along with the excellent performance, preliminary 08 EPA FE ratings are expected to reach 23/33 mpg city/highway. The BMW X5 using the same engine should achieve 0 to 60 in 7 seconds with an 08 EPA city/highway rating of at least 19/25 mpg. The 3.0L inline-six diesel uses the latest Variable Vane - Twin Turbo technology, an aluminum crankcase and third-generation common-rail direct fuel injection with precision-quality piezo-injectors for improved performance, reduced NVH, lower emissions and improved fuel economy. BMW’s Coup de Grâce to both the Federal Tier II/Bin 5 and California’s LEV-II emission standards comes about from the use of an SCR (Selective Catalyst Reduction) CAT with AdBlue injection reducing nitric oxides (NOX) and enabling nationwide rollout of these powerful but 50-state compliant super diesels to the American marketplace. The Blue-Performance system incorporates a DOC (diesel oxidation catalyst) just downstream of the exhaust manifold, a DPF (diesel particulate filter) housed in the same unit and an SCR catalyst with urea injection further downstream. This combination ensures effective reduction of nitric oxides (NOX) by way of a chemical reaction within the exhaust system initiated by the injection of a small dose of urea. The ammonia (NH3) generated in this process within the SCR catalyst converts the nitric oxides (NO and NO2) in the exhaust gas into environmentally compatible nitrogen (N2) and water vapor (H2O). BMW will use a two-tank AdBlue system with a heated active tank and piping (1.6 gallons in volume). The second passive tank includes an additional 4.5 gallons of urea solution allowing enough emissions compliant reduction to last through the distance traveled between oil changes. Like all BMW’s, the current 4 year/50,000 miles Maintenance Program will cover all routine maintenance including refill of AdBlue at no additional charge. Retail Pricing will be announced in the fall.
The HP and TQ numbers are impressive but not the FE... I guess all around the world we must be known as power hungry, b/c we only get the most powerful and not the most FE vehicles
Not to mention the most expensive vehicles. 45 grand for 28 combined is only .6mpg/dollar. Atleast give me 1mpg/dollar.
I believe, or at least I hope that it is only a matter of time before we can get small and efficient diesels here. You guys know that I love my Fit, but I would get rid of it today if Honda came out with a diesel (or for that matter, a thrifty hybrid). Louis B
Id love to see a 320d wagon with MT... My wife and I were just joking about seeing one of those one day... I wonder if this diesel will even be available with the MT. We need long-lived diesels like the w123 and w201 MBs of old... JMH
I know it isn't great but those are 08 numbers. At first I was thinking my 545 got 28 on the highway but it was rated for 24. Now this car with similar performance gets 33 on an 08 scale. So that is at least 50% better. Now the 545 was more like 5 sec 0-60 but either way it is close. And wouldn't those numbers exceed the 2020 Cafe standards? Just trying to see the positives. I would imagine that we will get the smaller diesels in the next few years. It takes some $$s to get a new engine through EPA testing.
And the 5-door. A 5-door 118d would be a great replacement for my car a few years down the road. The best performance comparison for a 335d might be the no longer produced 330i. The 330i had a 255hp, 220lb-ft I6, did 0-60 in around 6 seconds, and had EPA ratings of 17 city and 25 highway.
Yeah the urea I think is killing some of the performance and fe. Hopefully they will find a way to make these things more efficient.
Hi All: ___Remember that the BMW 335d would kill a TCH out on the highway as well as every mid or large non-hybrid sedan in town without breaking a sweat! Throw even the basics at this one and a TCH is going to have a tough time. I tried but was unsuccessful in procuring one for a review last fall but I believe it was C&D who pulled a 44 from it over a week of beating the hell out of it! ___For those that have not driven one of these new high pressure common rail super-diesel’s, they are truly a thing to behold in the FE department! To hell with the performance numbers although I always post them … They are not an attribute any of us will use but they are pretty to look at ___Good Luck ___Wayne
SCR with urea is fairly dependable, and doesn't affect mileage. There is the additional cost of refilling the urea tank though.
