Gm 3.5l Or Honda 3.5l In The Aura?

[whitesl2guy]

From the news I have read, the AURA will offer a 3.5 and 3.6 litre engine. I sincerely hope Saturn will be installing GM engines in the Aura, and not the Honda 3.5 (found in the Saturn Vue). It's already a crime that a Honda engine is in that vehicle, with the wide array of GM "sixes" available. Does anyone know? Dean

p.s. from what I have heard, the polymer panels are not offered on this model. That's a shame.

I'm pretty sure both of the engines available in the Aura are GM designs.

It's a GM power plant. I haven't heard anything to even hint at anything else. But with just the displacement numbers to identify the engine, it can get confusing.

I believe is the old pushrod 6 for the 3.5 and the Caddy 3.6 HF for the uplevel. ALso, that Honda 3.5 really puts the VUE in the top of its class. Great powertrain combo and a perfect mix of fuel economy and power.

[bobwill]

you can rest assured that both will be homegrown GM motors.
For one thing, the Honda 3.5L and GM 3.6L are nearly identical in performance, what would be the point of offering both?

I was just looking at the G6 specs for 2007. I was surprised that they will also start offering a DOHC engines in the car. I thought that GM should keep the pushrods to Pontiac and Chevy and the DOHC to the uplevel cars like Buick, Caddy and Saturn The G6 will have 4 engine choices: an I-4, a 3.5 L pushrod V-6 and 3.9L pushrod V-6 and the GM 3.6 DOHC engine in the top level GTP (along with the 6 speed auto found in the Aura). The funny thing is, you can only get a manual in the GT, not the top level GTP as you could last year. Weird stuff.

The 3.5L V6 that the Aura will receive is a GM design.

GM's internal code for the Aura's 3500 V6 is "LZ4"

The Honda-sourced V6 in VUE is coded "L66"

[gmhashope]

The 3.5 is an OHV engine that shares its newer design with the 3.9, it is not the same engine as the the old 2.8, 3.1, 3.4, or 3.5 with 201 hp currently in the G6. The 3.5 incoporates VVT and is E85 capable. It is basically the same 3.5 VVT V6 found in the Impala but will get 224 hp instead of the 211 hp version currently in the Impala. Also, the Malibu and G6 will get the 3.5 VVT V6 for '07 instead of the older 3.5 non-VVT V6 design.

BTW, the 3.5 OHV VVT V6 and 3.6 DOHC VVT V6 are GM designs.

What engine family is the 3.5 from?

Is it a new design?
A descendant of the 60-degree Chevy V-6?
A descendant of the 90-degree Buick V-6?

The 3.5L is not "old" by any means. It was all new for the 2006 model-year and has VVT and is E85 capable.

It is a 60-degree engine design.

I didn't think the Aura was getting the flex-fuel version of this engine. Do you have any pointers for this? I thought it was getting the LZ4, not the LZE.

Beginning this year there is a version of the 3500 VVT WITHOUT Flex Fuel (LZ4 is the correct RPO). This is going in not only the Aura, but it is replacing the OLD NON-VVT 3500 (LX9) in the G6, and Malibu. The LZ4 and the LZE are the same engine (in design and specs) one is just Flex-Fuel capable.

I don't know if the Aura will ever get the LZE E85 version or not, but I can't understand why they wouldn't. Unless they want to keep the E85 version for Chevrolet only- which would be stupid.

the honda is a SOHC v-tec, the GM engine is the one they'll be using for sure. But what surprises me is though GM wants to save money, they'll offer multiple engines which differ VERY SLIGHTLY in size and power. 3.5L @ 240hp vs. 3.6L @ 250hp or so, they're doing that with the outlook too, makes less sense.

[TBone1082]

I believe the base 6 cyl, being of older GM design will actually be priced similarly to the Toyota Camry 4 cyl model. Which would you choose? a 4 cyl base or a 6 cyl for the same money?

The 4 cylinder. Not everyone wants a V6.

The 3.5 is NOT of older GM design... I'm having a hard time understanding where people aren't seeing this.

I'm skeptical that it really will be the same money. If you shop around, you'd have no trouble finding a stripped 4-cylinder '07 Camry for $18,000. Will Saturn be selling us an Aura XE at that price? I'm not holding my breath.

The 3.5L makes 224 HP, not 240.

The reason GM is using the 3.5L as the base engine is to cut sticker costs. The 3.6L is expensive, and can only be in high-end cars.

[bgates2b]

Is the 3.6 a derivative of the Northstar?

Was Oldsmobile using that engine to (I want to say in Alero's but I might be mistaken)?

[hugh]

I don't think the 3.6 going into the AURA was in any version of Olds but it did debut in Cadillac CTS.
