that is not chrome lah... it is polished aluminium. Chroming are
for cheap american cars only... 
In Dubai the mtm Audi A8 polished was the eye-catcher. The car was
analysed and in many studies the enamel varnish of the aluminium
car body was removed. Furthermore the car was cleaned. After that,
the car body was poslihed with fine abrasive paper as well as
special polishes to high gloss. The blank dress must not have any
defects, because of the fact that retouching was not possible.
Finaly the car was protected with special clear varnish against
enivornmental impacts.
Because of the fact that it is impossible to polish plastic parts
like front- and rearspoiler, mirror house, side sillboard or also
fuel tank cap, they were enameled in a complex way to get a chrom
effect. Finaly they were polished with clear varnish.
Optics:
For the new top model of the Audi family we developed a discreet
aerodynamic package for better output. The front- and rearspoiler
is available in different materials like Carbon, aluminium
vaporized or to enamel in the current car-color. In the
MTM A8 in Dubai
interieur there are entrance strips as well as door mats with mtm
logo available. A steering wheel can be ordered soon. The kingly
leather accouterment can be worked over in the way you want to get
a kingly ambiance in the car. The offer of interieur parts are
rounded off by changed instruments scales - the speed indicator can
show more than 300 km/h.
Engine:
Between the cylinder heads of the 4,2 litres V8-aggregate a
compressor is put. Thus a performance of ca. 450hp and a torque of
530 Nm is reached which is leading to excellent driving
performance.
Suspension:
The air-spring-chassis was modified, so that a programming of speed
dependent heights is possible.
Wheels:
The 9,5x19" mtm-bimoto rims are SLC coated and snuggle excellent to
the high gloss polished blank dress of the luxury car.
