Talk:VR6 engine

message: I'm somewhat confused by the idea of the VR6 being put into the Touareg, since its primary advantage is its ability to fit well in transverse applications.  Nevertheless, I've seen several sources stating that the VR6 is indeed the Touareg's engine.  Here are a few:
I can see how these could possibly just be mistaken assumptions, but to me the best proof that the Touareg uses the VR6 is the fact that one of the Volkswagen R GT concepts brought to the 2005 SEMA show was a Touareg modified by HPA Motorsports, a company that specializes in turbocharging VR6's.  All three cars (a Jetta, a Passat, and a Touareg) featured twin-turbocharged VR6's.  I haven't seen pictures under the hood, but I can't imagine HPA suddenly pulling a twin-turbochaged Audi or Porsche V6 out of thin air when they've done all VR6 work for years.
I've also never seen a reliable source state that the engine in the Touareg and Cayenne is specifically NOT the VR6.  I would imagine, since everyone says it IS, that someone would try to contradict them if it's not the case. TomTheHand 21:41, 20 January 2006 (UTC)
thread_title: VR6 in Touareg

message: Hey Anais1983, just wanted to address the SOHC/DOHC issue with you.  I've read the rest of the paragraph, specifically the next part referring to a DOHC inline-six.  I promise.  You see, I'm the one who wrote it.
All VR6 engines have two camshafts.  The 12 valve VR6 has one camshaft per cylinder bank.  Each camshaft controls the all of the valves (both intake and exhaust) for that bank.  That's how a SOHC V6 works: two camshafts, and each camshaft controls one bank.  The 24 valve VR6 also has two camshafts, but one camshaft controls every intake valve in both banks, and the other one controls every exhaust valve.  That's how a DOHC inline-6 works: two camshafts, one camshaft controls all the exhaust valves, one controls all the intake valves.  The point of the paragraph is to compare the differences between the two engines: in the way the cams are used, one is V6-like while the other is straight-6-like.

message: Can anyone provide some insight as to balance with this engine? My understanding is that a 60-degree V-6 is inherently balanced, and that any other v-angle creates vibration that has to be remediated either through changing crank design and/or adding a balance shaft. At a 10.5-degree angle, these forces must be dealt with somehow.
Do all VR6's have a balance shaft? Is there anything unique about the crank and/or balance shaft in the VR6 design? Does the design result in a high production cost? (It seems that the latter is likely true, because when VW has had the engine compartment space and opportunity, like the last-generation Passat, they have used a fairly standard V6 rather than the VR6.)
I'd appreciate any insight on this from anyone familiar with the VR6 and V-engine balance issues. It seems important to understanding VW's achievment with this engine, and explaining why no other maufacturer has widely adopted anything similar. Meersman 22:41, 9 December 2006 (UTC)

message: Is the firing interval, 120 degrees, or something uneven?  How many throws, on the crankshaft? CorvetteZ51 12:21, 1 July 2007 (UTC)
replies: text: The firing interval is 120 degrees same as an inline 6.  Theres 7 main bearings, same as an inline 6. 24.8.219.134 (talk) 22:54, 17 March 2008 (UTC)

message: In my opinion there was a 2.8l VR6-version planted ino the Mercedes V-class (because due to the small enginebay the mercs own engine did'nt fit -so they bought the VR6 from VW).  Max—Preceding unsigned comment added by 93.131.142.132 (talk) 23:11, 12 November 2008 (UTC)

message: The article currently says: "In 1992, with the introduction of the Volkswagen Golf Mk3, a six-cylinder engine was available for the first time in a lower-midsize segment hatchback in Europe." I'm not convinced that this is entirely correct – it might hinge on the exact definition of "lower-midsize segment hatchback" – but the Mazda MX-3 might have been available a few months earlier. At the least the Mazda deserves a mention in this context. --BjKa (talk) 15:03, 7 November 2011 (UTC)
thread_title:  6 cylinders in small cars 

message: Throughout its existence, the Lancia firm has selected Vee engines with various narrow cylinder-bank angles (example : Lancia Lambda of the 1920's). The purpose was so that a single overhead camshaft could be used for both cylinder banks. The cylinders were indeed offset ; geometrically, that's the only way such narrow angles could have been used. Ít's not as though Volkswagen thought up the narrow bank-angle idea itself. 4.154.253.76 (talk) 19:15, 30 December 2011 (UTC)
thread_title:  Lancia had narrow-angle V-engines too 

message: Wouldn't it make more sense to replace the I4 with an I6? Seems to me, the idea behind the VR6 was to create a six cylinder engine shorter than an inline design and not as wide as a traditional V design. Using an engine with a different number of cylinders does not make a good comparison.  — Preceding unsigned comment added by 46.115.72.4 (talk) 15:07, 30 August 2013 (UTC)
