Yes, dual clutch transmissions with two gear sets are terrific, but too expensive thus far for entry level or even midrange cars. The best ones, like those on the AMG-Mercedes premium vehicles, allow downshifts that skip a couple of ranges and do rev matching as you go into the lower gear. That’s pretty awesome. The multi-disc clutch pack automatics are decent as well, and at least get rid of the inefficient torque converter. I too like a manual trans for all except heavy traffic commuting, which I no longer have to do. But I recall spending a month with a project truck, a Mazda diesel that I had fitted with a turbo, while commuting from central Jersey to NY through the Lincoln Tunnel. My knee was never the same. :-) Paul > On Jul 18, 2017, at 4:01 PM, Ken Waller <kwal...@peoplepc.com> wrote: > > I believe one of the benefits the makers of CVTs sought was increased mileage > by > tuning the engine/trans to operate in the optimum power range. > > However most people, use to the (gear) steps in an automatic find the > constant acceleration to be unusual and to some unnerving, resulting in > customer complaints and their effects on 'things gone wrong'. > The inclusion of 'steps' is the manufacturers effort to improve customer > satisfaction. > I believe its another case of the industry unleashing 'new' technology > without properly preparing the potential buyers for the different/unusual > characteristics. > > I've not seen any numbers but the inclusion of these emulated steps can't > have a big effect on overall economy. > > I also prefer a good manual transmission - I prefer the involvement - but > I've driven some of the better dual clutch vehicles and they are very hard > not to like and generally shift quicker than most can shift a manual. > > Kenneth Waller > http://www.pentaxphotogallery.com/kennethwaller > > ----- Original Message ----- From: "Igor PDML-StR" <pdml...@komkon.org> > Subject: Re: OT -Unexptected Good News from Subaru > > >> >> >> IMHO, those emulated steps on top of the CVT are ludicrous. >> One of the biggest advantages (and the reasons why CVT was invented in the >> first place) is the stepless, smooth transmission. >> So, this "emulation" is undoing the benefit. >> And I know that Nissan and Honda (and a few others) are doing that >> horrendous stupidity to satisfy people who need to be jolted every time they >> accelerate.
