Talk:DeltaWing

Untitled

2012 LeMans. the current text is too limp. it didn't make contact with another car, Nakajima made a huge faux pas by driving the Nissan off the road with his Toyota LMP1 racer. let the truth be reflected.85.83.19.103 (talk) 19:32, 19 June 2012 (UTC)

Not a Nissan engine

Updated to reflect engine from RML group (actually the same enginre as the chevy cruze race series) http://www.rmlmallock.co.uk/motorsport/prototype-sports-car 108.172.114.141 (talk) 05:52, 11 December 2012 (UTC)

Except it's not. RML specifically states it is a Nissan engine. Although rumored to be an RML-developed Cruze WTCC motor, that was just an engine used for testing of the car. The actual race motor is based on a Nissan Juke motor. The³5₉ (Talk) 06:46, 11 December 2012 (UTC)

The latest issue of Road & Track has an article about the DeltaWing. Per the article, it was made from Chevrolet parts with only the throttle body from the Nissan Juke. I'll add that reference in the near future, but I'll look for a difference between a testing motor and race motor. 72Dino (talk) 14:44, 11 December 2012 (UTC)

I found the article online here. It states that "The four-cylinder engine that the DeltaWing raced with at Le Mans was billed as a Nissan, but it was built largely from Chevrolet parts by England's Ray Mallock Engineering, which built the fours that won the 2011 World Touring Car Championship in a Chevrolet Cruze. The DeltaWing did, at least, sport a throttle body from a Nissan Juke." R&T is a reliable source . . . is there a reliable source to the contrary? 72Dino (talk) 14:56, 11 December 2012 (UTC)

There is nothing to indicate that this is a Cruze WTCC motor though, just that it carries over some parts. Basically the best way to describe it is as a bespoke RML motor with Nissan parts. The³5₉ (Talk) 20:55, 11 December 2012 (UTC)

Secondary source versus primary source

A reliable secondary source, Road & Track, has stated that the DeltaWing engine contains Chevrolet parts here. An anonymous editor has added this primary source to indicate that the motor is a "custom unit created by Nissan and Ray Mallock Engineering", and removed the R&T citation here. The IP also states that "According to RML the engine has no Chevrolet parts, all custom designed parts from Nissan and RML", although there is no citation for that so I don't know how they would know that unless there was a conflict of interest. I'm looking for feedback from more editors to resolve the question about the engine being made from both Chevrolet and Nissan parts. 72Dino (talk) 04:10, 19 December 2012 (UTC)

It seems fairly straightforward to me. Unless they can back these claims in their edit summary, their edits do not stand. It's possible they read it somewhere, but who knows. The³5₉ (Talk) 05:48, 19 December 2012 (UTC)

Motor Trend claims it's a Juke-based engine. --NaBUru38 (talk) 18:39, 10 January 2013 (UTC)

And Racecar Engineering asked the question a Nissan executive. The answer was: "t is a pure-bred racing engine but structurally and conceptually it’s very similar to our [DIG-T]". --NaBUru38 (talk) 18:43, 10 January 2013 (UTC)

The Q&A with a Nissan executive could be biased as they are out to sell cars, so I would not consider this a reliable source for this particular article (he's not going to say it was made with Chevy parts if they are paying to have their name on the car). The Motor Trend article does say the engine is "sourced from Nissan". That does not preclude the use of parts from other manufacturers, but it might mean that. I'm also not sure if the "Source: Nissan" in the article relates to the text or to the video. If it is to the text, it sounds like it might be just a press release. Hard to say which reliable source is correct. Maybe put both? 72Dino (talk) 19:37, 10 January 2013 (UTC)
