The 2UR-GSE (type 2015) has the Atkinson/Otto double cycles that reduces fuel consumption. On paper it's comparable to some turbocharged V6 competitors which is quite impressive. I would like to know from RC-F/GS-F/LC500/IS500 owners about their real life experiences with the fuel consumption of this engine. Please describe your usage scenario (daily or sporty driving or track driving) and your driving style. I would also like to hear about V35 from both LS500 and LX600 owners.
I've been recording the fuel efficiency of my BMW 440i xdrive with 6-speed manual and the upgraded 360PS tune of the B58 (regular 340/440 were 325PS). Over 6 months I averaged 20-21 MPG urban, 23-25 MPG combined and 31-32 MPG highway. I tend to drive as efficiently as possible: shift early, always use cruise control, keep 5-6 car lengths space, lift-and-coast instead of braking. But at the same time I often accelerate WOT when getting on a highway. The early B58 had a micro-hybrid system which uses a BSG to do energy recovery (a weak but noticeable regenerative braking effect), and it rewards lift-and-coast a lot. The car can stop with engine off for really long so the start/stop can really save a lot of fuel.
I ask this because some time in the near future I plan to buy a Lexus with 2UR-GSE. I love the B58 but even such a good turbocharged engine doesn't have the level of responsiveness I desire. I know this may sound dumb but I do try to get as much efficiency out of every type of vehicle I own.
