#1 of 55 3.5L power?
Sep 02, 2007 (12:06 pm)
Are their any 07 sienna owners here? If so how does the new 3.5L engine perform? i am thinking of trading our 04 in for an 07. i wanted to know how the new V6 performs while passing and when going up steep inclines? thanks in advance. =]

For me it has plenty of power - it doesn't transform the van into a sports car, but it does allow it to do what I want it to do. I can't really compare it to the 3.3L because I haven't driven previous Siennas.

Can someone post a 0-60 video of their 07 sienna? i wanna see how well it can accelerate, i would really appreciate it =]

It's quicker than any van really needs to be, put it that way.
The 3.3l was plenty adequate, don't get me wrong. 0-60 was in the 8 second range, I believe.
But the 3.5l puts it in 7 second range, even the slow pokes at Consumer Reports managed 7.7s to 60 in an AWD model.
So if you're looking for that extra little oomph, that's basically exactly what you'll get.
If you're not, the gearing is the same and with Direct Injection it can be extremely fuel stingy at low rpms. I've had 2 tanks where I averaged 30.6mpg. My worst tank so far was 23.x mpg, and that was around town.
Let me find that torque curve...found it. See how flat it is? It breathes better than the 3.3l at high RPM, so that's how it makes more HP, but it has 10% more torque all over the rev band.

Note: it's the one on the right. On the left is a V8.
The V6 actually has a flatter torque curve, surprisingly.
Note that from about 2200 rpm to around 5800 rpm, there is no valley in the torque curve at all.
I have that engine in my Sienna and love it.
#6 of 55 flat torque curve?

The flatter is better? well, i want to know how responsive is the Sienna's transmission to the newer V6?

Yes, flatter is better, because that translates to linear power delivery, i.e. you get similar acceleration at any RPM.
What you don't want are peaks and valleys that make it slow (or suddenly fast) at certain RPM.
When you stab the throttle the transmission gives you a gear right away, 2 gears take a little longer. With the power of the 3.5l you don't usually need 2 gears for passing, though.
I have yet to encounter a situation where I wanted more power with my van.

thanks alot, it is good to hear the 2007 sienna has all the power you need. have you driven it up some inclines yet? if so, how did it perform with the steep inclines? i really can't wait tell we can get an 07. Do you have an LE?

I have driven the LE '07 for 4 months now and the power is phenomenal. I live in West Texas and have driven it through some of the mountains out here and it moves easily up any incline. Remember, it still weighs about 4300 pounds. It is very tempting to just press the accelerator and drive it like a Nissan Maxima - but, it has 270 horses - and when you use all of them to pull 4300 lbs - you burn alot of fuel. Although capable of 26-28 mpg, I tend to really enjoy the engine as my previous vehicle was a V-8 powered LS430. I can get as low as 19-21 mpg in the city. Still beats the heck out of any SUV with the equivalent power in terms of gas mileage by at least 35-40%. It'd probably take a 5.3 liter V-8 to equal this pull in an SUV/truck. In fact, I've driven between San Antonio and El Paso at least 8 times with it on I-10 and I easily pass anyone or anything with ease - there is so much power still on tap at 70-80 mph. Any dad giving up a sports car for a minivan will love it. Definitely ditch the '04 Sienna. You'll fall in love with this power train immediately. A buddy of mine traded in his older Mercedes - couldn't afford the loaded LE - was looking at cheaper brands such as Kia, Nissan, etc., but after driving mine, he got a CE for under 23K simply because of this new engine. Despite two manual doors, he loves his minivan!

The Mid-Atlantic is flat as a pancake. I haven't been out to the Shanendoah mountains but even then they look like hills if you're from the Rockies.
Any how, for things like passing, power is abundant. Hit the gas and you are there, often I used too much throttle and need the brakes to compensate.
I also own a Miata, and while the Miata could do circles around the van, the van is a LOT quicker, no contest.
