TEST NOTES: Feels seat-of-thepants quicker in extended-range mode,
when it’s basically operating as a series
hybrid. When the battery is low, the
engine hums along until there is enough
charge to maintain performance.

ROADHOLDING,
300-FT-DIA SKIDPAD .............. 0.84 g
UNDERSTEER ................... MODERATE
TEST NOTES: We learned on the
road that the ELR willingly accepts
aggressive steering inputs. This translates
to very controllable behavior on the
skidpad. Tires howl as the limit nears.
FIRST STOP ................................... 172 ft
SHORTEST STOP ....................... 173 ft
LONGEST STOP ............................ 175 ft
FADE RATING ................................ NONE
TEST NOTES: With the exception
of zero pedal feedback, the brakes work
without flaw and our six test stops are
separated by three feet. A digital readout
in the dash says braking can generate up
to 60 kW when used in conjunction with
the Regen on Demand feature.

N O TA B L E H I G H L I G H T S GM’s HiPer strut adds significant unsprung mass,
but its crafty design reduces the tire’s scrub radius and the suspension’s spindle length—two
contributors to torque steer—in the quest for better handling.
