GENERAL MOTORS Owners of several midsize models now have an extended warranty on their electric power steering.
The biggest change is that some models now have a touchpad in addition to the red eraserlike TrackPoint button that sits between the G and H keys.
Gears, brakes and latching mechanisms vary; racks and fenders may be standard or optional but most models now have folding pedals to save more space.
All models now have a rearview camera, and trim levels starting with the midlevel EX-L get forward-collision and lane-departure warning systems.
The bottom line is the equilibrium sensitivity of the model was a bit on the high side (about 4C/2xCO2---most models now have it closer to 3C) while the forcing scenario (B) was a bit on the low side.
When the XC90 was launched last year, 30mph was the maximum, but with the launch of S90 and V90, all three models now have Pilot Assist up to 80mph.
A recent advance is that these models now have the ability to employ spatially variable hydrological and erosion parameters, the spatial distribution of soil particle size at user defined soil depths as well as several different flow direction algorithms.
The newest models now have enhanced gyro-stabilization capabilities and the ability to fly for triple the duration of what was possible only a couple of years ago — at a digestible cost of $1,000.
