Schumacher finally showed some under body shots of their new CAT SX 4wd electric buggy today. The layout and drive train has been much talked about but we've had to wait until today for a glimpse at the real thing.

The NiMh traditional cell car used 4+2 saddle pack layout.
Much of what's already been rumoured appears to be true, three belts and a forward direction motor layout and the car is available in two layouts for traditional NiMh cells or LiPo cells.
As previously mentioned, it's a 4+2 cell formation for the 'traditional cell' car, whilst the LiPo car runs a pack length ways down the car and the ESC, Receiver and Steering servo move to the right hand side to balance things out.
Transmission
3 belt transmission with efficient low tension belts running on large size CNC machined pulleys.
Adjustable internal transmission ratio (2.4, 2.6, or 2.8:1) to optimise ratio for brushed or brushless motors.
Motor rotates the same direction as the wheels creating a car with superb jumping responsiveness and no torque steer effect as is common with shaft drive cars.
Super free ball diffs with silicone nitride balls, pro spec thrust bearing, and lightened steel outputs.
Strong steel universal joint driveshafts.
Smooth twin pad slipper clutch with easy access adjustment.
Unique clamp motor mount to fine tune weight distribution, and allow motor changes without affecting gear mesh.
Industry standard wheel fittings.
Eccentric bearing housings for adjustment of belt tension and diff height.
Layshaft or front one way option. Overdrive front pulley option.
Internal gear cover.
Chassis
Optimum weight distribution with ‘4+2’ NiMh batteries or stick pack lipo layout.
2.5mm aerospace grade carbon fibre chassis and top deck.
Horizontally split transmission housings for ease of maintenance and diff access.
Ultra narrow chassis design to minimise grounding on roll.
Rigid servo mount directly onto transmission housing for precise steering.
Dirt protected with tight fitting body and undertray.
O ring wing mount system to avoid crash damage.
Purple titanium turnbuckles included.
Suspension
Class leading suspension geometry with durable components and a huge range of adjustments to set up your CAT to any track conditions.
Adjustable rear roll centres, inboard toe-in/toe-out, anti squat and track width.
Adjustable front roll centres, inboard toe-in/toe-out, track width and rake angle.
Pro spec shocks with titanium nitride shafts, CNC machined pistons with recessed ‘e’clips, threaded collars, twin O ring sealing and diaphragm volume compensation.
Strong and rigid 4mm carbon fibre shock brackets.
