I was trying to find some details about our 1.4T engine. Correct my details if I get something wrong.
9.5:1 Compression
DOHC with VVT on both cams (DCVCP)
Coil on Plug ignition
Hypereutetic pistons
Cast Reinforced Crank (not sure how it's reinforced)
Forged Rods
Aluminum head
4 valves per cylinder with sodium filled valves
Turbo built into the exhaust manifold
Plastic Intake
Injector size?
Boost?
Low-mass hollow-frame cast iron block
Dual overhead camshafts with variable valve timing
Chain-driven cams
Roller-finger camshaft followers
Piston-cooling oil jets and integrated oil cooler
Variable-flow oil pump
Electronically controlled thermostat.
The 1.4L’s turbocharger is integrated within the exhaust manifold, for reduced weight and greater packaging flexibility in small vehicles. A reinforced crankshaft and stronger connecting rods deliver additional strength to support the engine’s pressurized power and torque over a wide rpm band.
No fancy direct injection, aluminum blocks, or hybrid technology. The 1.4T seems to be the culmination of the last 20 years of turbo technology with an emphasis on economy, midrange power, emissions, and reliability.
It's worth mentioning that the Sonic has a true front mount intercooler opposed to the sandwich design of the Cruze.
