Does the new RL have drive by wire technology?

 

Yes. It is mentioned on acura.com in the specs/details section.

 

what is DRIVE BY WIRE tech?

 

"In most cars, a mechanical cable connects the accelerator pedal to the throttle valve. The RL uses the all-electronic Drive-by-Wire Throttle System™, first developed for Honda Formula 1 racing engines. It senses accelerator pedal motion, then a computer weighs this data against vehicle speed and engine data in real time and opens the throttle accordingly. The pedal feel is more direct. Acceleration is smooth from rest, and immediate at normal cruising speeds, for quick passing. Because control is more precise, throttle response is quick and sporty. Exhaust emissions are reduced, and performance and fuel economy are improved. Drive-by-wire facilitates communication between the engine, the ABS and Vehicle Stability Assist (VSA®), enabling a more coordinated reaction by these systems when they are engaged. In the RL, throttle position and shifting are coordinated electronically, so the shift "feel" is more refined."

I find cars with that drive by wire throttle stuff are much easier to keep at a constant speed.

 

"By wire" control systems that aren't mechanically linked. Since everything but the throttle has direct mechanical links. It is more like throttle by wire.
