Hi guys, Like to check with you all. does the Cerato engine displacement 1,599cc is a CVVT Engine? As I understand that RIO has also an engine displacement 1,599cc and was rated the engine CVVT on the BOOT LID.
Is there a difference between V1 pioneer batch and a later batch?

Cerato V1 is only a DOHC, but V2 onwards up to Forte/Koup is CVVT. sorry, not sure about RIO. BTW, you can call-up C&C to enquire on such information.
difference in terms of what? (btw V1 pioneer batch and later batch). What's "later batch", BTW? Not very sure what information you want, but basically on a nutshell ...... (a) V1 engine block is cast iron; whereas V2 onwards is "cast aluminium Alloy". But the former is more durable than the latter. (b) V1 exos is in the front and airlet is rear; whereas V2 onwards is exactly the reverse. (c) V1 run on timing belt; whereas the others in timing chain. (d) factory tuning of V1 is slightly lower than others.

What I meant was Cerato V1, RIO, Verna, Getz, Matrix, Elantra are using the same engine displacement at 1,599cc comparing to the latter V2, Forte, Avante and New Elantra which are using the newer Displacement engine of 1,591cc.
So I conclude that since the Cerato V1, RIO, Verna, Getz, Matrix, Elantra are using the same displacement, I will assume that they are the same engines. My question is that RIO 1.6 and Verna 1.6 had their engines equipped with CVVT on their cars as pasted on their Cars by Manufacturers thus my question whether Cerato V1 is a CVVT. But since you've mentioned that it is DOHC might be that the RIO and Verna had a revised technology.
My next question is the "Later Batch" is still on the variance of V1. According to an acquaintance that the Earlier batch Manufactured say; 2004-2005 is much more fuel consuming to those manufactured in say; 2006-2007??

V2 dohc ma...... dual cams all timing chain 1599 cc timing belt Sorry, I am confused. Isn't V2 on CVVT rather than DOHC? V1 is on DOHC while V2 is on CVVT? I was asking this is because of my fuel consumption is actually better than those reported on my V1. My average is 11.66km/l Highest consumption was 10.21km/l while the lowest consumption was 12.84km/l that is why I asked as the reported fuel consumption by other members was much higher than mine.

cvvt may be a feature. I'm not reading enough to tell. but dual cam is engine design. just like lancer glx 1.6 engine is sohc.

Cerato V1 is NOT using the CVVT and the Rio's Alpha Engine is not the same Alpha II in V1, Matrix, Getz 1.6.
The CVVT is slightly newer and not brought into the V1 Cerato.

Anyway, got this off somewhere;
The alpha family continued at least through 2005 in Hyundai's Accent economy car. The G4ED Alpha II was enlarged to 1.6 L (1599 cc) thanks to a 76.5 mm bore and 87 mm stroke. A 10:1 compression ratio produced 104 hp (78 kW) at 5800 rpm with 106 ft·lbf (144 N·m) of torque at 3000 rpm. The Alpha II has a cast iron engine block and aluminum DOHC cylinder heads with 4 valves per cylinder. It uses MFI fuel injection and features forged steel connecting rods. The Alpha engine family is produced in Ulsen, South Korea.
CVVT Alpha II was introduced in the 2006 Accent. Power output also increased to 112 PS and 108 lb/ft torque. It has COP(Coil-On-Plug) ignition, graphite-coated pistons and new cylinder block design to increase strength. Throttle body bore has increased from 48 to 52 mm. Engine and automatic transmission control is now integrated into one module and the PCM is located in the engine compartment. It is ULEV-certified in all 50 states.

Thanks for the clarification. Now I understand that the engine in Rio and Verna 1.6 is a different engine compared to ours. So we share the same engine with Getz, Matrix, old accent and Elantra. So ours are using Cast Iron DOHC G4ED as compared to an updated engine of CVVT Alpha II. Guess CVVT Alpha II gives a better mileage as to our G4ED

Technically it should give better fuel economy because;
1. Using an aluminium block, thus it's much lighter.
2. Higher power output to propel the car.
3. CVVT is much more efficient.
