AWD in RX?

If one looks at the power distribution in the square in front of the steering wheel, one sees that power is ALWAYS sent to the rear wheels when starting or accelerating. When no longer accelerating it stops sending power to the rear. The button with the 4WD symbol is there to lock the differential when needed, So far I've never had to use it.

Based on other cars explanations and some real world use, in a few situations you want all 4 wheels spinning, just to keep going, rather than have them sense slippage and shift between front and rear. Deep snow and mud are two where you just want to plow through as best you can with all the wheels trying. While not the same, the lock switch gives you the effect of a true manual 4WD, where there is no control of slippage.

My comparison right now is a 2018 Honda Pilot AWD and I will say the Honda AWD is superior. I can floor it and I get tons of grip with no wheel spin. The active torque vectoring is also noticeable in the curves.
With RX it seems like the front wheels easily lose grip even during partial acceleration from a stop...the traction control is constantly flashing even on dry pavement. The display says 50% of the torque is going to the rear tires instantly but it doesn’t stop the front wheels from slipping during initial acceleration.

I have to agree with PWMDMD, the Honda AWD system, with Sand mode, Snow mode etc., is superior to the Lexus. Just go to TFL truck and watch a Ridgeline climb offroad; it works very well despite the junk tires. The Pilot has the same AWD system as the Ridgeline. The Subaru beats them all though, so if you’re in a Subie, no worries because that symmetrical AWD is awesome. I owned a 2005 Forester XT while living in the Lake Tahoe area, and it would go places my F150 4x4 couldn’t go.

Whats up with this why doesn’t everyone just make their AWD system like Subaru. Is it patented or something

If I do the same thing in the pilot no detectable wheel spin and certainly no traction control intervention.

New 2019 RX350 with 2500 miles on it. I can break the front tires loose 100% of the time on many different paved roads by simply smashing the gas down. If I do a small rollout it’s fine. If I lock the differential it’s fine. The AWD system is just not fast enough to engage the rear tires before they lose grip.

Wow, I've never been like - have to much respect for my machinery. Ever heard of "mechanical sympathy", tyres, brakes, gas plus all the moving parts in a car are stressed more when driven hard - costly and detrimental to the longevity of the vehicle. But that's me.

You and I drive alike, so, just for the fun of it, go test drive a 2019 BMW X3 M40i. It will put a smile on your face, and beg for full throttle in the sport plus mode. This Bimmer is very quick. I owned an ‘18 X3 M40i, and it was an absolute blast to drive. Bought the Lexus to make the wife happy, but, if the stars align right, I’ll be in another X3 M40i.

At 35K miles and 3 or 4 years no one will be able tell if this car was babied or driven hard so my attitude is have fun while you own it!
