Does this hybrid system start and stop every stop light like other hybrids such as the jeep i just witnessed at a stoplight, stop then start, thanks

 

Sort of. It switches to Ev at stoplights. It is not like a car that the engine abruptly shuts off at a light, then restarts when the drivers foot is lifted off the brake. The 250h starts moving on Ev mode, then the engine kicks in when extra power is needed. You do not notice it, it is very smooth and quiet comparatively.

 

thanks for this, hearing a car starter come on like the jeep i seen just seemed wrong, again thanks !!!!!!!!!!!!

 

Major difference between a conventional Start/Stop and a Toyota/Lexus hybrid is that nothing is belted
to the motor in the Lexus. Motor off but the A/C keeps coolin' and the electric power steering lets you
steer along left turn lane and drive through lanes. The restart is also different, rather than an oversize alternator
yanking a belt or a conventional starter working overtime, the Motor/Generator unit simply spins up the
IC motor through the planetary drive.

 

awesome tech info!!! thanks very much!!!!

 

is the ux a direct corolla engine and trans?

 

The UX200 powertrain is lifted out of the Corolla. Not sure about the Hybrid. I think it maybe lifted from the Corolla or Prius as well. I hope that doesn't put you off. A lot of powertrain components are shared between Toyota and Lexus.

 

Yes, a lot of the newer European and American cars do what you describe - start engine noise when your foot lifts off the brake. To me it's annoying as heck. So much for a quiet ride, right? As long as you stick to most Japanese cars, you'll never have this "problem." Gosh I hope Lexus/Toyota never does this.

 

Toyota/Lexus already has Start Stop techonolgy. It depends on the market. Lucky for us, the North American market will not get start stop tech for now.

 

Nearly yes for both 2L and 2L Hybrid powerplants. Engine/transmisison programming differences exist as well as increased sound deadening materials, engine mounts and other structural elements added to the UX to make it feel more premium in the powertrain/NVH department.

 

@macmaster @MX73 If Start/Stop is done well where it is nearly seamless as is automatically the case with the Toyota/Lexus hybrid powerplant, personally I welcome it. My Stinger has the Start/Stop and I am very pleased with it's fairly smooth operation, significantly smoother than the A4 I had. Sure, you hear the engine come on/off but doesn't bother me personally and being stuck in traffic saves me some premium fuel/costs.

 

it won't, i was just looking for solid info on this, i have an 06 corolla that runs like new with never an issue and 180,000 miles,, so i can definitely say this doesnt put me off!!!!

 

It's actually a new line of engine. The M20A-FKS was recently introduced in the new 2019 Corolla Hatchback. There is the M20A-FXS for the hybrid that is not carried over from the Prius.
