Alfa Romeo has officially
previewed the new 4C sports car concept fitted with the
powerful 1750 turbocharged engine as well as the TCT
transmission and the brand's "DNA" button, just as it
makes its debut at the 81st Geneva Motor Show this
morning, while at the same time VW Chairman Ferdinand
Piech has again registered his keen interest in Alfa
Romeo at the Swiss motor show.
In its press release
issued this morning Alfa Romeo closes with a final line
that claims the 4C is destined for production: "This car
is not simply an exercise in style created for the motor
show; it will be on sale in 2012 and is set to reinforce
Alfa Romeo's global growth."
While the 4C Concept was
getting all the attention this morning, VW Chairman
Piech last night at a special event suggested that in
VW's hands the Alfa Romeo brand could reach 400,000
units sales by 2016. Last year it sold just 112,000
cars. By contrast Fiat CEO Sergio Marchionne is much
more optimistic for Alfa Romeo, he plans to reach
500,000 sales by 2014. Marchionne had also previously
targeted 300,000 units by 2010.
The overall shape of the
4C, while developing some thinking from the 8C
Competizione, shows a strong similarity to the Lotus
Evora, particularly in the glass house form, the glass
engine cover and the overall design language shapes.
Other external influences melded into the new project
include the venting in the frame around the engine cover
which is reminiscent of Ferrari's 360/430. Piecing
together some information from the press release, Alfa
Romeo says the 4C has a "length of approximately 4
metres and a wheelbase of less than 2.4 metres." The
length is around 27 mm longer than the KTM X-Bow (3.73
m) which would be accounted for by the new enveloping
bodywork, although more curiously the X-Bow's wheel base
is 2.43 m, implying a shortening of the wheelbase due to
the new rear subframe.
For the 4C Concept Alfa
Romeo has used learning gained with the 8C Competizione
in the areas of carbon fibre, aluminium and rear-wheel
drive, adding to the mix technology derived from models
currently on sale: the 1750 turbo petrol engine fitted
with direct injection, the "Alfa TCT" twin dry clutch
transmission (which recently went on sale in the Alfa
MiTo) and the Alfa DNA dynamic control selector.
Using the X-Bow's carbon
fibre monocoque along with aluminium for the rear engine
housing structure and the crash boxes and confirming
that the new bodywork developed by Dallara is "crafted
completely from carbon", has allowed Alfa Romeo's
engineers to impressively keep the weight of the concept
car to a claimed 850 kg (X-Bow "Street" by comparison is
790 kg) and while the power output isn't revealled, Alfa
Romeo says that the "extensive use of carbon, which also
plays a structural role and guarantees exceptional
agility with a weight/power ratio which is lower than
4 kg/HP." However this is still just a concept showcar
and kerb weight is bound to rise if the car does make it
to production in the future, particularly as Alfa Romeo
has a strong reputation for being unable to keep weight
from spiralling on its production cars.
The name "4C Concept" is
meant to be suggestive of the sports driving pleasure
from the "4 cylinder" 1750 turbo petrol engine "which
offers over 200 HP" - says Alfa Romeo. Already featured
on a number of models in production, for example the
Giulietta Quadrifoglio Verde, the engine boasts
cutting-edge technical solutions such as direct
injection, dual continuous variable valve timing,
turbocharger and the revolutionary scavenging control
system which eliminates turbo lag.
Located centrally in the
rear of the vehicle, the engine in the 4C Concept
ensures a performance which matches or exceeds that of a
3 litre engine whilst still delivering the moderate fuel
consumption which is typical of a compact, 4 cylinder
engine. Coupled with the new automatic "Alfa TCT" twin
dry clutch transmission, launched only a few months ago
on the MiTo and which will soon be available on the
Giulietta, the 1750 Turbo petrol engine in this
application allows the 4C Concept to reach a claimed top
speed of over 250 km/h and to accelerate from 0 to 100
km in under 5 seconds. The vehicle also integrates its
Alfa DNA technology.
The Alfa Romeo 4C Concept
has a sophisticated suspension layout, retaining the
high quadrilateral at the front but adding a MacPherson
strut arrangement at the rear, to ensure agility and
road handling. This solution, along with the rear-wheel
drive and the weight/power ratio, should add up to
driving pleasure, enhanced even further by the weight
distribution of 40 percent on the front axle and 60
percent on the rear axle (compared to a 37:63 split for
the production X-Bow).
