INTRODUCTION
________________________________________________________________________________________
The birth
of VEXUVIUS **(for TRC variant) was inspired my enthusiastic into rock
crawling activity via radio control models. In real life rock crawling is
very much an adventurous sport and need skilled man in handling both machine
again the environment where physically unpassable obstacles are crawlable.
It took me months to to fully indulge my passion in technical work of the
crawlers. I realised having an ultimate 4x4 machine doesn't mean it has
something to do with speed but its all about skilled driving and torque
power. To make this activity affordable by immerse the activity into virtual
reality VEXUVIUS was built with its physic inspired by rock crawling r/c
models...i hope in reality a full scale VEXUVIUS will one day reborn.
VEXUVIUS was named after the mountain god VESUVIUS which reflect its power
and mighty over the top of high mountain summit hence thus its
characteristic as it was.
THE DESIGN
________________________________________________________________________________________
With enthusiasm to recreate rock crawling version of MAXXIMUS with more
modern exotic looks i decided to start making a new design from scratch with
all dimension measurement and outline similar to MAXXIMUS. The first
plan to built 4 seater with rear truck bed and 4 door but cut back to 2 door
two seater hatch back design. MAXXIMUS have classic truck like frontal
and rear appearance but i planned VEXUVIUS to have more sedan car like
or exotic looks such as aero headlights and rear lights, smooth aero
outlines and mid mounted exhaust to give it a sporty looks.
Few signature remains constant
such as the "X" beam and flat sharp lines remain as trademark in
all "CD" designated marking. To show evolution
from one species to another through DNA evolution of design XEXUVIUS carry
on legacy of XAVAGE partial genetic imprint into its physical self but in a
form of super off-roader genre. The rear "X" beam, headlights case, lines of
narrow dark panels, sharp mirror like center lines and aerohead like
windshield carries on its genetic to present day. Not to forget it also
share partial looks of classic MAXXIMUS overall physical outline looks, in
VEXUVIUS the rear hatch, frontal and rear face improved with more
aerodynamic and modern looks. However due to the fact VEXUVIUS built as
exotic off-roader and crawler the chassis have only 2 doors, 2 seaters and
enough compartment to store survival tools and spare of adventurous journeys
and lightweight concern.
Front and rear tip end distance to wheel base
are shorter compare to standard 4x4 models allow more clearance to navigate
steep angle surface especially during rock crawling without hitting the
front and rear tip first. The main headlights and rear lights are
mounted higher above the wheel fender level away from possible mishap at
prone impact area plus added areodynamic modern looks like a sport exotics
light case design. Exhaust muzzle integrated in mid section of the
rear panel for mishap avoidance and sporty looks, also another means to
maintain constant design trademark throughout lines of SupermotoXL
Designs.
CHARACTERISTIC
________________________________________________________________________________________
VEXUVIUS
**(for TRC variant) is very
torque-ish truck concentrate more on "power to climb" gear ratio with locked
differential for all around slipless traction over the rock. Its features
solid axle, higher ground clearance and short length chassis almost Jeep
like size for manouverability over rough and narrow turn terrains. The tire
are very claw-ish for greater and deep gripping power over rocky and loose
obstacles. Full time 4wd transmission and powerful vertical braking power.
The front nose and rear length from the main wheel hubs are very short allow
more clearance and climbing angle away from ground and object obstacles.

TRC
"Torqued Rock Crawler" variant.
________________________________________________________________________________________
The "TRC" (Torque Rock
Crawler) version is the original specification of VEXUVIUS. The
specification built for serious over the rock expedition climb any obstacles
beyond and 4x4 vehicle limitation. With high suspension lift kit, serious
rock crawling tyre with bead locked wheels, winch, k-bars, rollcage, 5.9L V8
hybrid engine huge torque power, full manual control axle slipper the
XEVUVIUS TRC variant will put mother nature against the machine to the test.
TR
"Trans Rally" variant.
________________________________________________________________________________________
The "TR" (Trans Rally)
variant designed for fast paced off-roading, very aggressive dirt blaster,
full time 4WD and good for running down the rally track gone Dakar Style
tourer. With V8 engine, stock rally wheelsets and rigid chassis, spare
wheels, roll cage protection and higher supension clearance the "TR" will
make a big leap over the sand dunes.
UR "Urban Rider" variant.
________________________________________________________________________________________
The "UR" (Urban Rider)
variant designed for tailored urban driving, simple styling, less
off-roading accessories and mid height setup on the suspension. Completely
basic type of 4x4 vehicle for everyday use. The tyres and wheels are
standard compact SUV type tarmac threading suits for smooth and low rolling
resistance thanks to lightweight CNC metal matrix alloy wheels. It runs
below 250hp on v6 engine, with out differential lock option on axle
transmission, stock peformance suspension and just good enough to drive
around the country side with family and friends.
SUMMARY
________________________________________________________________________________________
VEXUVIUS
have shown several important value that are usefull for our next future
development of super off-roader both in design, engineering and conceptual
theory. Simulated research and development on VEXUVIUS shows that there no
limit on what design and ideas we could implement as long we have will to
create it. I learn the most important thing in my life when it comes to pull
out new ideas for an automobile designs, "we don't have to follow others, we
follow our own ways". Uniqueness is our trade and ideas is our talent.
