 Federal-Mogul Corporation : New Federal-Mogul Gallery-Cooled Piston Improves
              Power and Refinement of Downsized Gasoline Engines

              Lightweight Elastothermic piston limits knock and
           improves durability of high-power spark ignition engines

Southfield, Michigan, July 30, 2013. Federal-Mogul Corporation's (NASDAQ:
FDML) Powertrain Segment is introducing a new Elastothermic^® piston, designed
for next-generation downsized gasoline engines. It allows vehicle
manufacturers to further increase power density and compression ratios without
compromising refinement or durability. The new piston combines the low mass
and low friction benefits of its advanced Elastoval gasoline piston
architecture with an improved cooling gallery design located higher in the
crown of the piston. The new design decreases crown temperature, reducing the
risk of detonation, or "knocking", in hotter, higher pressure engines, while
simultaneously maintaining high structural strength.

"Engine manufacturers continue to utilize higher levels of turbocharging to
improve CO[2 ]emissions, fuel economy and performance," said Gian Maria
Olivetti, Chief Technology Officer, Federal-Mogul Powertrain. "Our innovative
new Elastothermic gallery-cooled gasoline piston enables these downsized
engines to run at higher power levels and compression ratios with low NVH and
outstanding durability."

The Elastothermic piston is the next step in the continuous development of the
company's advanced Elastoval piston architectures for gasoline engines.
Advanced Elastoval is characterized by reduced boss gaps and a smaller
distance between the side panels, which are angled or even multi-angled and
use down to 2.5 mm section thicknesses. In most cases, a convex boss structure
is used, with optional weight-relieving pockets in the pin direction.

Testing has shown that the Elastothermic piston gallery reduces the piston
crown temperature by 25 Kelvin (K) to 30 K. The cooler crown and top-ring land
area allows engine designers to calibrate the engine for more power, torque
and fuel economy while minimizing calibration compromises to avoid
pre-ignition "knock." It also allows for the development of future engine
designs with higher specific outputs.

The Elastothermic piston also decreases the temperature of the first ring
groove by up to 60°C down to below 250°C which reduces carbon deposits and
ring sticking, helping to keep oil consumption low and improving sealing. The
lower operating temperature, in turn, improves scuffing resistance, allowing
more cost-effective solutions for ring and groove tolerances. The reduction of
knock also reduces wear and deformation of the first ring groove.

"Piston crown temperature is a key factor in piston durability and the fuel
economy improvements that can be obtained by downsizing," said Arnd Baberg,
Chief Engineer, Piston Product Engineering, Federal-Mogul Powertrain. "The
lighter weight and smaller section of gasoline pistons makes integrating
cooling galleries far more challenging than in diesel pistons. Federal-Mogul's
materials and production expertise has allowed us to develop more precisely
controlled casting processes that produce high-strength, lightweight pistons
with galleries."

Vehicle manufacturers in Asia, North America and Europe are developing engines
with the new piston design that was developed in Federal Mogul's R&D-center in
Nuremberg,  Germany.  Production  is  scheduled  to  start  during  2013   and 
Federal-Mogul will present Elastothermic piston technology at the IAA Show  in 
Frankfurt from September 10-13, 2013.
