Nissan's 4.0L V6 vs. Toyota's 4.0L V6...what's Toyota doing wrong???

Nissan's 4.0 V6 (which I believe is a VQ derivative?) makes:
265 hp @ 5600 rpm - horsepower
284 ft-lbs. @ 4000 rpm - torque
EPA estimated fuel consumption: 17/21 City/Highway

Toyota's 4.0 V6 (which spawned the new 3.5L in the IS) makes:
236 hp @ 5200 rpm - horsepower
266 ft-lbs. @ 4000 rpm - torque
EPA estimated fuel consumption: 16/20 City/Highway

One would imagine that if it made less power, it would at least get better fuel economy. Especially considering that the Tacoma weighs over 400 lbs less than the Frontier (4307 lbs vs. 3875 lbs) and has slimmer tires (P245/75R16 vs. P265/70R16).

The information is from edmunds.com. I'm not sure if Nissan is also using SAE standards. What's Nissan doing better than Toyota??

Nissan has always been pushing numbers. Toyota only recently been going into the power wars. One thing for sure though, the Tacoma is better built than the Frontier.

It was my understanding that Toyota and BMW are the only ones currently using the new SAE standards.

What are they doing wrong?

Making an engine that will last forever instead of just push high numbers when you buy it.

and yes, this is an apples and oranges comparison. I have not seen Nissan's revised hp/tq numbers for the new SAE standard.

Sure Toyota's engines last a long time, but I haven't really heard many complaints about the VQ series engines. They're not very fuel efficient, but they're powerful and reliable - which is why Nissan uses them all across their product portfolio.

I do agree that the Tacoma has much better build quality and is more refined than the Frontier. I actually drove my cousin's Pathfinder Armada recently, and though that thing has crazy torque, it's got the worst build quality (1 inch panel gaps every which way) and is extremely ugly.

How many years has the VQ been in service?

I'm not a nissan freak, but I do know toyota has a long history of engines/cars that run forever.

You wouldn't have been exaggerating if you would have put in one VITAL piece of info:

+-2,000 miles

Nissans get TERRIBLE gas mileage. Just wait until the real world numbers come out.

If you wanna hear complaints... check out people reviews of Nissan Maximas after they had them for a couple years.

I'm assuming the Nissan Murano has the VQ in it too since its a 3.5. We had one as a rental car for 2 days... S model, fwd, CVT. 1,100 miles the check engine light came on and back to Enterprise it went... I'm guessing that wasn't a fluke.

You're half right. Right now, it's just GM, Toyota and Honda using the new standards, and Nissan was quite vocal in its opposition to them. Worse, they're not obligated to use the new standard until they come out with new engines.

Probably not. A client at work had a Murano, and some CVT-related issue led him to break his lease early and get an Acura MDX instead.
