You know little about transmissions , do you? The ratios can't be pre-selected in such transmissions, they can't be 'chosen', by the way, I think the ratios are perfect, so we agree to disagree. With this many gears you really don't care about each individual gear, you care about spacing and the first and last gear and you provide a common multiplier through the differential gear.

 

I think he was saying the spacing wasn't ideal, especially between gears 1, 2, and 3. (I know in the 6-speed, the difference between 1 and 2 is quite atrociously far)

 

It's not about different strokes. Lexus would very much love a turbo engine, but they're conservative and taking time to develop it out. With powertrains, Toy/Lexus often takes a wait and see approach. BMW is usually first to come out with new powertrains. They've done like 12-15 different turbo engines (sometimes different turbo engines within the same lifecycle) in the span Lexus did one. It'll come soon.

 

Actually BMW is just on its 3rd gen of turbo inline sixes ...still way more than Lexus with the 2GRFSE... there was the twin turbo N54 (prob the best out of them all)... the single turbo N55 and now the modular B58, which shares its core with an inline 3 and 4 cylinder.

 

^^ There, fixed for you (lol)

 

Some nice upgrades for 2018 just announced...I've been waiting for the adaptive lighting and more hp and nice to have 10 yrs standard for lexus app.

For at least Canadian market, 2018 IS FSport Series 2 and 3 will be getting memory seats (power tilt/telescopic steering wheel) and parking sensors... about time lol

 

The real news here is a Torsen® Limited-Slip Rear Differential Now Standard on 350 RWD F SPORT !!!!!!!!

 

Does this mean the IS will now get the triple beam headlamps?

 

These are some nice upgrades for 18. Wish I had the AFS and memory seats for my 17!

 

You should go with the 18 V-6 Camry-This car is awesome. I was thinking of trading my RC350 for one. The features alone with the panoramic roof is a good value for this car. You can't get all of those things on a basic ES or IS for the money.

 

Up 5 hp, will the general public really be able to tell any difference in hp? 306 to 311 I mean why did Lexus do this, marketing move or will we really be able to drive it and say yeah I can feel it's a bit faster?

 

I wonder if we can buy the part and bolt onto a 14, this is a great surprise

 

You will not feel the 5 hp.

My guess is when they made the other changes to the engine, they were able to eek out 5 more horsepower fairly easily and decided it was worth it to claim some sort of increase. Marketing...

 

Na. I'm talking iterations.BMW does several updates called "Tus" or technical updates to many of their engines. They tend not to recycle the same engines, particularly lately. They've got a TON of new turbo engines currently being developed right now. From 3 cylinders to 12.

These are some of the BMW engines currently in the works... in addition to the tons they have currently which after a year or few, are already extremely outdated.

• B37 will not get any major updates in RWD models anytime soon. The transverse (FWD) version has a TU planned. No new versions are planned.
• B38 will get TU for all existing versions (starting with the recently updated F48 sDrive18i), with the exception of the 1.2L one and the one that goes into i8. No new versions are planned.
• B47 is simple: TU for all versions with the exception of longitudinal 16d (will be dropped?)
• B48 is starting to get its first TU (now available in Europe in F48 sDrive20i). The TU version will soon find its way into more UKL models, and then we'll see it in the CLAR cars, either with 07/18 "model upgrade measures" in G30, or at G20 intro. The only new version of this engine currently planned is the one that will go into UKL M35i, B48A20T1. The longitudinal versions will remain limited to 20i (B48B20M1) and 30i (B48B20O1).
• B57 - TU for 30d and 40d, but not 50d.
• B58 will get a TU (probably mid-2019), and with the TU will come a new version, B58B30O1. Note that up until now, all models, even the highest output X3 M40i, have been using the M0 version of this engine. O1 will probably take us even closer to 400hp, and I won't be surprised to see new model names (M45i? though don't quote me on this).
• N63 is currently in its third iteration (TU2), and there will be the fourth one (TU3) that will add two new versions, one below (M3) and one above (T3) of the current O2 (to be succeeded by O3). This actually looks somewhat illogical to me, since the future top version of B58 and the future bottom version of N63 should end up really close to each other in output. I suspect one of them may not actually happen.
• N74 used in the brand new Phantom is actually one iteration ahead of the one in M760i (TU2 vs TU1) in addition to being bigger (6.8L vs 6.6L). M760i will catch up with its own TU2 soon, but there will also be something new, probably RR specific (Cullinan Black Badge?): N74B68M2.
• S55 will not get a TU, but will be replaced by S58 (full name S58B30T0), as we already know.
• S63 just got its newest upgrade in F90. It's going to stick around for a while.
