Lexus is moving away from sedans and toward SUVs

Interestingly, a heavier rear end assists braking, but induces more front wheel spin on an AWD vehicle.
While a heavier front end assists front traction & acceleration on an AWD vehicle, but it hinders braking.
In the end, that's why most engineers go for 50/50 balance; a bit rear heavier on a full fuel tank, and getting lighter on the rear as the tank empties.
Internal combustion engine = good low torque
External combustion engine eg gas turbine, turboprop, turbofan & turbojet = great for high speed torque.
More cylinders = more power, smoother, but less efficient & more expensive.
Supercharger = response & low rpm power
Turbocharger = midrange torque & power
Electric motor compressor + exhaust driven turbo = best of both worlds
Hybrids = pros & cons
EV with lion = good
EV with better than lithium ion = even better
Hydrogen fuel cell powered electric vehicles = great range, but less performance, while infrastructure takes longer to set up.
FWD = entry level
RWD = premium
Transverse mount in front of front axle = entry level
Longitudinal mount behind front axle = premium
Coupe = low
Sedan = standard
Crossover = tall cabin & tall ground clearance, similar to traditional 8 feet ceiling versus modern day 9-10 feet ceiling.
Sports = speed
Luxury = comfort
There's no big deal; they're all good, in different ways.

Not exactly. Many trucks are designed for stopping with a full load, the brake system is designed to move more power to the front brakes when the vehicle is lightly loaded or not unloaded at all. When loaded, the truck senses the weight a distributes the braking power more evenly.

However, increased vehicle weight slows down the rate of deceleration.
These two factors added together produce the final outcome in braking.
Eg, a 2nd rate sat nav system won't hinder RX sales, nor will transverse layout in front of front axle, nor cheap single lower arm suspension, because RX sales determined by many many factors added together.

You are incorrect. Adding weight to the vehicle at the rear will reduce the traction while braking. Adding any weight serves no benefit. Trucks are completely different, as they are designed to carry loads, adding weight to a Tundra will change the way the power of the brakes work according to the design of the truck,.
