The most potent Audi V6 TDI ever to enter production powers
executive class Audi models to 62mph in a fraction over five seconds and
returns up to 44.1mpg
- Advanced new biturbo TDI engine
heads diesel line-up in A6 Saloon, Avant, allroad quattro and A7
Sportback ranges – OTR prices from £43,810
- Available now in A6 Saloon and Avant and A7 Sportback, and later in 2012 in A6 allroad – first deliveries in spring
- 313PS from 3,900-4,500rpm, 650Nm from 1,450 to 2,800rpm
- A6 Saloon 3.0 BiTDI quattro – 0-62mph in 5.1 seconds, governed 155mph top speed, combined MPG 44.1, CO2 169g/km
- Sound actuator in exhaust system accompanies remarkable performance with sports car exhaust note
Knockout punch in a velvet glove comes courtesy of a formidable new
313PS Audi Biturbo TDI engine, which is now available for A6 Saloon and
Avant and A7 Sportback models. The new twin-turbo V6 is notable not only
for being the most powerful six-cylinder diesel engine ever offered by
the Vorsprung durch Technik brand, but also the sweetest-sounding.
Available now in A6 models priced from £43,810 OTR, and from £51,645 OTR
in the A7 Sportback, it combines trademark Audi TDI refinement with an
exhaust-mounted sound actuator that enables it to deliver its mighty
650Nm output to the tune of a distinctly sporting soundtrack.
Slotting in above the single-turbo 204PS and 245PS versions of the
3.0 TDI that already feature in the A6 and A7 Sportback ranges, the
latest V6 has a two-stage turbocharger group that delivers a maximum
boost pressure of up to 3.2 bar, helping the A6 3.0 BiTDI quattro Saloon
to lunge at the horizon and pass the 62mph marker in as little as 5.1
seconds, and the A6 Avant and A7 Sportback to do the same in just 5.3
seconds. An electronically limited top speed of 155mph is common to all
versions.
Like the existing TDI engines, the new star performer is backed up
by technologies from the Audi modular efficiency platform, including
start-stop and recuperation systems and the innovative thermal
management system that quickly brings the coolant and oil up to their
operating temperatures. With their help, combined economy in A6 and A7
Sportback models is on an equal footing at 44.1mpg – an impressive
figure given the high outputs and low acceleration times involved.
Sound actuator
Thanks to an innovative actuator in the auxiliary channel of the
exhaust system, the BiTDI A6 and A7 Sportback models don’t sound like
they should be capable of such level-headed economy figures. The
actuator system essentially consists of a speaker which imposes a
defined oscillation pattern on the exhaust flow and transforms the
typical TDI exhaust note into a more sonorous roar that is closer to the
output of a high-performance petrol engine.
Without exception, power is transmitted from the BiTDI engine via an
eight-speed tiptronic transmission to the latest generation quattro
all-wheel-drive system, which features a self-locking centre
differential and torque vectoring for optimum traction and stability. A
sport differential which distributes power in continuously variable
proportions between the rear wheels is available from the options list
to sharpen and quicken response even further.
The mighty new BiTDI engine is available in conjunction with SE and
S line specification in the A6 Saloon, A6 Avant and A7 Sportback. The
forthcoming A6 allroad quattro, due to open for order in February, will
also offer this exceptional unit.
Stand-out features common to all these models include satellite
navigation linked to a 6.5-inch retractable colour monitor, Milano
leather upholstery, the Audi drive select adaptive dynamics system
controlling throttle response, transmission shift points and steering
feel, the Audi parking system plus, light and rain sensors, cruise
control and keyless go push-button engine ignition.

ed 160 hp and 129 ft-lb of torque. It’s likely a streetfighter like the 6 would be given performance tuning to bump up peak output somewhere near 180 hp at the crankshaft.
Obviously Honda must contend with this performance imbalance for its EVO6 to compete with BMW’s Concept 6. Perhaps underneath the EVO’s stylized cylinder-head covers is a new DOHC valvetrain and four-valve cylinders, which would go a long way in bringing more horses to Honda’s trough. The addition of gasoline-direct-injection technology would allow a bump in compression from its current 9.8:1 ratio to a figure commensurate with BMW’s 12.2:1.
two automatic shifting modes in addition to a bar-mounted toggle for operating the six-speed gearbox manually. With the introduction last year of the dual-clutch transmission in the VFR1200F, we’ll assume that technology would make it to this concept, and, likely, to the next Gold Wing.

Resting on a 66.9-inch wheelbase, the VMax scales in at 684 lbs full of fluids and boasts nearly 200 hp. The K1600GT already weighs just 703 lbs wet, so the Concept 6 could easily match the Max. But for the EVO6, that giant Gold Wing engine will ensure an optimistic mass of just below 800 lbs.
