The Audi A8 hybrid combines the
performance of a six-cylinder with the fuel economy of a four-cylinder
model. The sprint from 0 to 100 km/h (62.14 mph) takes just 7.7 seconds,
and top speed is 235 km/h (146.02 mph). In the standard cycle, the large
sedan consumes just 6.3 liters of fuel per 100 km (37.34 US mpg) on
average – a CO2 equivalent of 147 grams per km (236.57 g/mile), and
easily the best in its class.
In all-electric mode, the Audi A8 hybrid
can cover roughly three kilometers (1.86 miles) at a speed of 60 km/h
(37.28 mph). Top speed in this mode is 100 km/h (62.14 mph). The driver
can choose between three driving programs, on the basis of which the
hybrid manager – the control unit in the drivetrain – selects the best
suited of five operating modes.
With a curb weight of 1,870 kg (4,122.64
lb), the Audi A8 hybrid is by far the lightest hybrid sedan in its
class. This top value is due in part to the fact that the additional
components weigh in at only around 130 kilograms (286.60 lb) and also to
the ultra lightweight body. Featuring an aluminum Audi Space Frame (ASF),
it tips the scales at just 231 kilograms (509.27 lb).
The chassis of the A8 hybrid also benefits
from Audi’s expertise in ultra lightweight construction, combining
excellent ride comfort with sporty handling. The links are made of a
lightweight alloy; the power steering uses a special electromechanical
drive. The Audi drive select dynamic handling system and adaptive air
suspension with damping control are standard. The large 19-inch wheels
sport a special hybrid design.
