TDI vs BlueTec Diesel Cold Start Comparison
Since I have two diesels for now, I thought I would take the opportunity to record the difference between a cold start of the TDI and BlueTec.
Both are V6, direct-injection turbo diesel engines. Both produce 400+ lbft of torque. Mercedes dropped this OM642 engine in favor of a 4-cylinder for 2014.
The Audi is much, much faster. The Audi is also quieter and at least 20% more efficient than my BlueTec. The BlueTec is for sale, if any of you want that "old" feeling.
The videos are kinda boring, unless you're interested in the character differences between a Mercedes and Audi diesel.
Both cars had only a 2-3 second delay between pressing the start button and firing up. The glow plugs work instantly. I'll have the first person POV videos up later today. The ambient temp was 16 degrees for the TDI and 19 degrees for the BlueTec. Both have QuikTrip diesel from the same station.
