NON-LIABILITY OF MANUFACTURER
The purchaser of the vehicle assumes full liability for the safe construction and operation of the Ariel Atom 2
whether the vehicle was assembled by the purchaser, a thi rd party garage, or by Brammo Motorsports, LLC.
The Ariel Atom is a high performance vehicle intended for track use. Construction of high performance vehicles
involves inherent risks in materials selection, systems d esign, and vehicle construction. Operation of high
performance vehicles involves inherent risks associated wit h exercising materials, designs, and assemblies at
the limits of performance constraints. The operator’s i ndividual characteristics and techniques will contribute
notably to the performance of the vehicle and the stre ss placed on designs, materials, and construction.
Ultimately, decisions regarding the safety of the vehicl e are made by the owner or operator. By purchasing th e
vehicle, the owner accepts full responsibility for the saf e design, materials selection, construction, and
operation of the vehicle and relieves Brammo Motorspor ts, LLC of any and all liability for any and all injury or
death associated with any aspect of the vehicle.

GM DRIVETRAINS
The Ecotec 2.0L SC (Supercharged) is compact and lightw eight, and its Eaton M62 Supercharger adds 40
percent more power to the Ecotec 2.0L engine compared to a naturally aspirated version. The M62
supercharger utilizes a helical roots compressor and integr al pressure control, producing a maximum of 12-19
PSI of boost. The boosted intake flow exits into an all-new matched intake manifold with an integral air- to-
liquid heat exchange intake charge cooler system. A comp act single-track, six-rib belt supercharger drive
system utilizes a linear tensioning device to further st rengthen the already impressive system performance and
durability. A microprocessor manages the M62 supercharge r, fuel, direct spark delivery systems and the
engine’s 68-mm Electronic Throttle Control (ETC) system . ETC delivers outstanding throttle response,
improved reliability and better integration with cru ise control electronics for greater overall performance a nd
drivability.
The Ecotec 2.0L SC engine is built with a six-quart oi l sump and a crankshaft driven pump. A block-mounted
oil cooler, or optional remote cooler, is included to e nsure proper lubricant cooling that promotes long engi ne
life.
The 2.0L SC engine is built exclusively at the FGP (Fi at-GM Powertrain) engine facility in Kaiserslautern,
Germany. This plant uses a die-cast production techniqu e that yields a block that is well suited for high-stress
applications including turbocharging and supercharging.
Often referred to as the Global Four Cylinder, the starting point for the 2.0L SC is the Ecotec 2.2L (RPO L61).
This engine has leveraged GM Powertrain’s worldwide de sign and engineering capability by drawing on the
best practice of technical centers in North America and Eu rope. The Ecotec 2.2L created a template for
subsequent global powertrain development that laid th e groundwork for engines such as Powertrain’s new
Global 3.6: V6. Most important, the Ecotec 2.2L is a world-class gasoline engine with obvious benefits for the
