Narrative:
Whiny 1 RNAV arrival into dfw. Star was loaded and confirm by both pilots with emphasis on speed and altitudes especially being new stars. With autopilot engaged in LNAV and VNAV path aircraft remained on path and sped up in speed even with full speed brakes deployed. Vanco intersection to berms. ATC was notified and asked for relief. No scratchpad messages and light winds less than 10 knots. ATC coordinator contacted on arrival.redesign intersection to provide more distance to allow greater flexibility. Crossing 2000 feet in 4.4 at 250 knots is very tight in normal conditions.
