1.Mégane Coupé Concept
 Mégane Coupé Concept is powered by a 200hp (147kW) 2.0 Turbo petrol engine which delivers torque of 280Nm at 2, 600rpm and peak power of 200hp at 5, 800rpm to ensure punch and flexibility at all engine speeds for everyday motoring pleasure....
 
2.TCe 100
 The turbocharger includes an " overpower " feature which temporarly boosts power output in 2nd, 3rd, 4th gears at engine speeds of more than 4, 500rpm (5hp extra torque)....
 
3.F4R RS - 200 hp 2.0 16V
 Lively and discreet at low engine speeds, it proves its sporting credentials at higher speeds.... Result : more torque at lower engine speeds and more power at higher speeds ; a high compression ratio of 11.5 : 1 obtained through the well designed shape of the chamber and piston....
 
4.Particulate filter with exhaust-mounted injector
 Advantage : unlike other solutions available on the market, the regeneration process no longer depends on vehicle speed, engine speed or journey length....
 
5.Organization & Development
 Physical values are set for each feature (e.g. noise level in decibels at given engine speed)....
 
6.TCe 130
 Like its smaller sibling, the TCe 100, the TCe 130 combines a small engine with a low-inertia turbocharger that is responsive even at low engine speeds.... Thanks to this tumbling flow of air the combustion flame propagates more efficiently, improving torque at low revs without impairing performance at higher engine speeds....
 
7.Acoustics
 The M4R 2.0 gasoline engine : excellent acousticsThe 16V M4R 2.0 delivers the driveability of a high-capacity engine, allying power and torque at low engine speeds with performance at higher speeds.. This lively engine is also the quietest in its segment.. To achieve this result, the M4R relies on : balance shafts to reduce boom ; a silent timing chain ; a twin-mass engine flywheel that eliminates the transmission of vibrations to gearbox gears at low engine speeds (on versions equipped with the TL4 6-speed manual gearbox) ; a plastic cylinder-head cover to reduce noise ; stiffened oil pan and cylinder blocks to eliminate vibration, lighter pistons, rods and valves..
 
8.2.0 dCi (M9R)
 This minimizes vertical oscillation of the engine caused by the movement of alternative weights (pistons, rod) and moving parts (rod, pistons) to reduce vibration linked to the 4-cylinder architecture. A twin-mass engine flywheel acts as an acoustic filter to reduce boom at low engine speeds. A silent timing chain favors acoustic comfort....
