Holdens SIDI?

[scottmuecke]

thought this forum would be the best place to ask about the 'new' SIDI engines. Props to Holden for finally putting the constantly upgraded buick 6 to rest.

According to TV ads its the bee's knees.
From what ive been told the technology is not new and in fact they still dont perform as well as the japanese makes in the 380 and camry.
Will these engines improve the 0-400m times at all?

Just 1 more thing, how does the Sportivo compare with the SV6?

Holdens haven't used a buick motor for almost 15 years.

Direct injection has been in the states for a while, they have gained more power but it has exactly the same amount of torque as a vz.

depends what your after from a car.

Holden will be rear drive rather than front and a vz will get just as many kms out of a tank than a ve with one of these motors.
I'd be looking a an aurion if it didn't bother you which wheels drive the car.

If you're talking about the Buick and Ecotec, the Buick was last used in the VR, and the Ecotec finished when the VY did. The Alloytec, a completely new engine, has been in use since the VZ, and SIDI is an upgrade of the Alloytec. Holden put the "constantly upgraded" (in reality, 2 revisions) V6 to bed long ago.

not really, remember they are making the same power from a smaller capacity motor, so really yes it has more poer if you keep things in proportion, the 3.6 has more torque and power than the vz,

fuel economy, i believe holde is doing more testing with them in that green vehicle challenge, i think they are getting 6.5L/100km on highway runs, so that better than lowest 7.5 my vz has ever got

imo

Your VZ has the weight penalty of being a wagon, so your economy is damned good. Is the VZ wagon heavier than the VE?

[andyman]

my weight is comparable to a ve, but with me travelling with travelling and 2 other people id say nudging 2.1T gvm


the 7.5 is from the trip computer average over 300km's of driving on the hume highway between exter off ramp and lachlan valley way to borowa/cowra turn off,

over all tank consumption is usually about 9lt/100km as i do more driving around town before i fill up again

a FWD will always perform a little better than a RWD.... they don't lose as much power through the drive train. a real PITA to drive though.... torque steer annoys the crap out of me.
i am keen to test drive the SIDI Commodore... at least drive one that has a few K's on it. That was one thing i liked about the alloytech was the fact that it revved cleanly and was pulling strong all the way to red line. I haven't floored an SV6 but the V Series Omega i had was still pulling hard at 145kph in 2nd gear. the ecotech was valve bouncing at 125kph in 2nd.

aurion? ugly ass cars! i think they go well with the Mahindra

[VKCOMMO]

i think they go well with the Mahindra

they look like they have been squished in from either side

i stand corrected the sv6 has 10nm more torque over the vz but on the other hand an omega might have gained power but has lost out in torque now down to 290nm from 330.

if he wants a holden and wants economy he should get a maloo, won the green car challenge.
