“Body-on-frame�
Spaceframe with base standard platform PQ34-35 Volkswagen Golf 4G.
Easy customization Cheaper/easy maintenance
Cheaper production, flexibility, mass production
Platform chassis + upper monocoque steel body
Chassis/Frame Beetle vs New Beetle
130 km/h max speed
208 km/h max speed
1.1-1.6 L / 30-60 hp Gasoline engine Flat-four or horizontally opposed-four
1.2-2.5 L / 100-170 hp Gasoline/Diesel Engine (turbo) Inline-four engine or straight-four
Compacted, balanced and robust Extended, less tall, without radiator (air cooled)
Smooth, compact, efficient, cheaper, less consumption Taller and bigger (water cooled) more complex, most common motors
Less efficient, more expensive, more consumption
Motor/Engine Beetle vs New Beetle
3-4 Speeds manual/semi automatic
4-6 Speeds manual/automatic
RWD Rear Longitudinal Engine Rear drive Rarely used today, mainly in Porsche
FWD Front Transverse Engine Front wheel drive Common use today
Good indoor space, compacted, good acceleration, easier steering system
More packaging space, good indoor space, supercompacted system
Tend to oversteer, less packaging space
Tend to understeer, less traction, posibly heavy steering
Transmission Beetle vs New Beetle
Rear Longitudinal Engine
Front trasversal Engine
Air/oil cooling without radiator
Water cooling R134a
Central fan force air entrance. Oil support
Use of special liquid. Combination between water/air
Robust, adapted to extreme conditions, less maintenance
More efficient today, necessary Problems with liquid (freeze), more maintenance
Less efficient today (complex systems)
Refrigeration Beetle vs New Beetle
Recirculating ball
Power rack and pinion
Worm and cap nut steering
Hydraulic assisted. Most common
Robust, not common today Heavy, more expensive
Cheaper, less backlash and greater feedback Less efficient mechanical advantage
Steering Beetle vs New Beetle
Front: ( ) 4 Transverse torsion bars
Front: Mc Pherson with 2 shock absorbers
with (
) 4 upper/lower trailing arms. Rear: ( ) 2 Transverse torsion bars
(
(
(Independient each wheel) Rear: Solid beam axle bars, trailing link with 2 shock absorbers (non independient)
) 2 trailing arms and torsion bars with 2 Wing axles
More stability, vehicles with front wheel drive Mc Pherson (more space)
Independient suspension, and ) 1 Hydraulic shock absorber in each wheel
Suspension Beetle vs New Beetle
Hydraulic drum
Hydraulic Disc with ABS
Robust, cheaper Bad cooling
Better cooling More expensive
Front and rear
Ventilated front, solid rear

Aerodynamics Beetle vs New Beetle
Area of turbulence
Extended lenght smooth front air pass
Rear spoiler
Wheels cover properly
Bottom part totally flat
Smaller ground clearance
Smaller
