driveline as needed. The battery is comprised
of 288 pouch cells in 12 modules,
with a fifth of its total weight comprising
the pack's scalable aluminum construction,
its interior a framework of
extruded and pressure-cast profiles.
The ID.4's onboard charger is a Level
2 unit with an 11-kW maximum rate, and
it's also equipped with a DC fast-charging
capability at a maximum rate of 125
kW; VW claims the ID.4 can go from a
5% state of charge to 80% in about 38
minutes with 125-kW charging. The
ID.4's battery pack uses a liquid-cooled
floor plate to help keep the battery in
the ideal temperature range of around
77°F (25°C) to benefit power output,
DC charging and battery service life.
The ID.4's high-voltage-system warranty
provides that the battery will still
have at least 70% of its original capacity
after eight years/100,000 miles.

The steel unibody ID.4 AWD is 4.6 in. (117
mm) shorter than Volkswagen's Tiguan,
at 180.5 in. (4,585 mm), with a 0.9-in.
(23-mm) shorter wheelbase (108.9
in./2,762 mm). Despite the smaller footprint,
the 99.9 ft2 passenger volume is
very similar to the Tiguan (101.1 ft2), as is
cargo volume behind the second row
(30.3 ft2 vs. 33.0 for the 2-row Tiguan)
and with the seats folded (64.2 vs. 65.7
ft2). Where the ID.4 AWD trumps an
AWD Tiguan is curb weight at 4,782 lb
(2,169 kg), vs. 3,847 lb (1,745 kg). The
ID.4 AWD model's towing capability is in
a useful range, rated at 2,700 lb (1,224
kg) for a braked trailer, 1,650 lb (748 kg)
for an unbraked conveyance.
" In terms of dimensions, we're within
a few inches of length and width from
CR-V and RAV4, the segment leaders.
So exterior wise, very similar, " explained
Jeffrey Lear, product manager of electric
vehicles for Volkswagen of America.
" But on the interior with our MEB platform,
it's packaged really nicely.
Batteries in the floor. Obviously, no
combustion engine. Wheels are pushed
out. And the longer wheelbase means
more cabin and trunk space. "
With the high-voltage battery located
between the axles, VW claims the AWD

ID.4's weight distribution is very close
to 50:50 while keeping the center of
gravity low. The front suspension is a
strut-type with lower control arms, coil
springs and an anti-roll bar. A first for
Volkswagen, the ID.4's steering rack is
located in front of the wheels' centerline,
which it claims maximizes cornering
stability. The rear features a compact
multi-link suspension with coil
springs and an anti-roll bar. Compared
