Actually, they aren't. The RL's 3.5l V6 (B35??) is based on the old 2.7l V6 from the Legend. The Odyssey's 3.5l V6 (J35) is based on the Accord' 3.0l V6 and is a much newer engine.
:doh:
Learn something everyday. But it still stands, the RL has a 3.5L (not a 3.0L as originally posted) and gets marginally better mpg than the GS430 (not the other way around as originally posted).
