RPO LLT - 3.6L DI V6 w/VVT
The first overhead cam engine ever in a Camaro, the 3.6L (217 Cu. In.) V6
is the engine of GM's future fleet. Originally available domesticly in the
Cadillac CTS, this engine has grown in it's applications. For Camaro, this means
a high tech proven powerplant for today and the future. While there are several
variations and states of tune, Camaro receives the pick of the litter, the
Direct Injection version which pumps out an estimated 300 hp @ 6400 rpm, and
273 lb/ft of torque at 5200 rpm. The 300hp number is only five shy of the 2002
Camaro Z28's 5.7L LS1 engine.
The engine block and cylinder head are constructed of cast aluminum with iron
cylinder bore liners cast in place. The engine is oversquare with a 3.70" bore
and a short 3.37" stroke allowing for a 7,000 rpm redline. Usually short stroke
engines are noted for being a bit down on torque (anybody remember the 1967-69
Camaro Z28 302 engine?) but the capabilities of modern technology alieviate most
of that issue. The 3.6L engine has variable valve timing which constantly changed
the valve timing for optimum performance with a minimal emission footprint. This
allows the engine to have a torque-based camshaft when needed, yet also a
performance-oriented cam when called upon.
Direct Injection is a fuel injection system which sprays fuel directly into
the combustion chamber resulting in a more precise fuel delivery for greater power
and fuel effiency while at the same time lowering vehicle emissions. The V6 powered
Camaros are estimated to deliver 26-mpg on the highway.
RPO L99/LS3 - 6.2L V8
The latest darling of GM's long lived small-block V8 with be the driving
force behind the 2010 Camaro SS. There are two variations of the engine, RPO L99
which will be mated to the six-speed automatic transmission and the RPO LS3
which will be mated to a manual transmission. Both engines have the same
dispalcement, however features and power outputs vary.
The L99 engine will be a high tech powerhouse, with its net power estimated to
be 400 hprsepower @ 5000 rpm and 395 lb/ft of torque @ 4500 rpm. The engine will
have GM's Active Fuel Management which allows the engine to operate in eight or
four cylinder modes for increased fuel effiency. AFM (AFM) operates by energizing
the valve lifters to be on or off. When in four-cylinder mode, the valves are
closed and the fuel supply shut off. Another fuel saving feature is the Variable
Valve Timing (VVT) for optimized valve timing.
If the Camaro SS is equipped with the six-speed manual transmission, the engine
forgoes the VVT and AFM. With the direct mechanical link (no torque converter),
the engine can not be set up to switch from four cylinder to eight cylinder mode.
For compensation, the engine is projected to deliver 422 hp @ 5000 rpm and 408
lb/ft of torque @ 4500 rpm, The Redline for the LS3 is 6600 rpm versus 6000 for
the L99.
Whichever variant of the 6.2L is chosen, the engine shares many of the same
features such as aluminum cylinder heads and block with cast in iron liners for
durability. The crankshafts of either engines are nodular cast iron, which happens
to be common to the Corvette as well, and has undercut and rolled fillets. The
main bearing caps and connecting rods rely on powdered metal manufacturing
method for increased strength. For lowered advertised maintenance, an engine oil
life monitor lets the owner know when it is time to change oil.
