Ike gauntlet Tacoma 3.5 vs Canyon 2.8 diesel...surprising uphill times

Did you include the 2 timing belt replacements in that, including labour to be fair?

I've done the same thing just for kicks. I ended up around 300,000 km including belt replacements. If anything goes wrong on the Colorado Diesel before then, and let's face it that truck is a GM with the disaster waiting to happen at high mileage G80 gov bomb locker in the rear, then the calculation would go to the Tacoma no matter how high the mileage.

 

No doubt. It surprises me on here how many people compare a 2500 HD Denali to a Tacoma. Around here you'd get laughed at for hours for doing that. They are so different it's not even funny and the use for each is totally different.

 

I did not include any maintenance. And yes, I did not have faith that the GM would even still be running by the time it got to the break-even mark at 230,000 km

 

Guess I missed that part.
Then the best comparison would be a manual on all three trucks with a V6.

 

welp, im stumped then as well.

 

Horse power is not what you use for pulling or towing. That is torque. Seen a Canyon break traction while hauling a car and car trailer. Compare a 3.5 diesel to a 3.5 gasser in standard clothing and the gasser will lose in towing every time. Don't see any 426 ci gasser Kenworths now do ya?

Maybe the Taco beat it by a few seconds, but the Taco was being flogged in the process. The smog machine was just easing along.

 

I believe they said they did use the ECT PWR button for that test.

 

I came up with a similar number--167,000 miles to break even. But that was a few months ago, and at the US prices at that specific time. I think I based it on the option charge for the diesel engine, and on Colorado gas vs diesel MPG rather than Colorado vs Tacoma. Either way, around 10 years of ownership for the average person, and most won't have the vehicle that long.

 

What is your definition of "flogged"? Both had the gas pedals on the floor. The rpms are just the nature of the gasser vs. the diesel with the gasser near redline making peak horsepower and the diesel at 3400 rpm, also making peak horsepower.

Let's do some math rather than just saying stuff like "torque is used for pulling."

3.5l Tacoma at 6000rpm in 2nd gear is running at 69 mph. It makes 278 hp which is 243 lb*ft at 6000 rpm. Multiply by the overall gear ratio of 8.17 and the Taco is putting 1998 lb*ft to the rear wheels (a bit less due to drivetrain losses).

2.8l Duramax at 3400 rpm in 3rd gear is running at right at 60 mph. It makes 181 hp which is 280 lb*ft at 3400 rpm. Multiply by the overall gear ratio of 5.3 and the Duramax is putting 1482 lb*ft to the rear wheels (a bit less due to drivetrain losses).

So who pulls better now? Both engines are at their redlines by the way.

 

Nice comment, except there is no 3.5 L Diesel available in the Colorado. That's a very odd displacement for automotive Diesels that's usually reserved for I5 engines.

I don't see many semi's or freight trains breaking the pavement or track from a stop either.

There are lots of fuel trucks and farm grain trucks around here that are gassers. They fell out of favor due to the cost advantages of Diesel over a million mile vehicle that will stick around for damn near ever. Also, a large transport vehicle like that doesn't need to get a 0-60 time above 20 seconds with a load. Try driving a small truck thought that takes that long to accelerate. You wouldn't want to own that.

Both trucks were flogged. Watch the video. This isn't a "loss" for Diesel nor does it need to over explained. The Tacoma is likely geared better to get the most out of the engine when it's pushed to the limit.

 

Maybe cause you don't own one?? Just sayin...

 

V8 powerstroke, Isuzu, inline 6 cummins, vs a Tundra with the same load? Like sized engines.
I'm sure an inline 3.5 diesel would fare better than the 2.8 even at 600cc improvement. Either way you slice the comparison, the diesel is going to be better for towing and that is undisputable. You can hammer, flog, abuse the Taco all you want to beat the diesel. But the diesel is going to keep running much longer than the beloved Taco.
I wish Toyota would offer a diesel in the Taco but I guess that isn't going to happen.
If Nissan comes out with the 3.0 Cummins that is going to give the Tacoma a run for it's money or take over first.
You have a point if you are talking small truck and acceleration, but is there a substantial diff? IDK.
I can tell you that when I pulled my 3000 lb off road pop up over 9500 feet here in Colorado my '14 Tacoma felt it. I don't think it would have killed the diesel that bad. I did trade up for the new 3.5 hp and torque curve numbers. At elevation I bet those hp torque numbers drop more for a gasser than a diesel?
Diesels work less for the output and hence they last longer.
I'll pull my camper here soon again, but I'm not going to breed that 6000 rpm and second gear for 60 mph regardless of the duration.
If you want to see real world diesel vs gasser. Sit on Laveta Pass and watch full size tucks unhitch tow vehicles to make the climb while powerstrokes and cummins blast it at 65mph with 5th wheels.
Maybe the little diesel is not in a fair fight or just outclassed.

 

Given that @Rock Lobster finds his 2nd gen insufficient for power even with the S/C I doubt the 3rd gen naturally aspirated Tacoma would get him excited.

 

Not like sized trucks. The Tundra is a 1/2 ton. All of the engines you mentioned sit in 3/4 tons. Even the new Titan XD with the 5.0 L Diesel is only able to tow a little bit more than the Ford F150 Ecoboost.

I doubt that. Have you owned a newer Diesel. They don't hold up like they used to with all the new emissions technology. Lose an injector and you might pay as much as it would cost to buy a rebuilt engine for a Tacoma.

Agreed. Toyota wants to make as much money on the Tacoma as possible and more engine options would eat into their profit margin.

An F150 does 0-60 in just over 6 seconds at 2000 feet of altitude with almost every engine offered. The Colorado at altitude can't break 10 seconds. While racing isn't the point of a truck that's a big difference when you are trying to merge on a highway which most drivers do every day.

As for Nissan, unless they make good money on the Titan, I don't know if they will even offer a truck line anymore.

According to these results a Diesel Colorado would of had to of slowed down and chugged over. Which is fine. If that's what you want. Ike is done at altitude just FYI.

They turn less but the nature of Diesels is also completely different. Older Diesels tend to cost less than gassers but when I worked in local fleet operations we had a hell of a time keeping modern Diesel costs down. We ditched our 3/4 tons just as I was leaving for F150's with the 3.5 L Ecoboost. Then again, we didn't tow a ton with those trucks. It was mostly for payload which the new aluminum F150's filled in for nicely.

6000 RPM on a gas engine and 3500 rpm on a Diesel... either way you are pushing the fuck out of that engine and shit will likely break faster.

Again, you aren't comparing apples to apples. The gas engines in most 3/4 tons have half of the torque of the Diesel option. That's where the huge difference is. In this case, with the Tacoma against the Colorado, the difference is much smaller. Hence....

It's not fair. It's an engine designed for the 3rd world to power the truck in a country that doesn't care how fast they get there or whether or not the tow rating is accurate.

 

Damn, guess I'll have to swap pulleys too.

 

Well not too much buyers remorse around these parts so I can't be too far off.

I do like the 15 Taco tho and I'd have bought one IF I didn't test drive my truck - I didn't buy for the "looks" thats for sure. Its a pick up truck ... not going to win a ton of points in the style department just for that reason.

 

Sadly, the third gen section is populated with people either defending their trucks to the death or flogging their buying decision. Just browse the daily posts. A good chunk of them are from dissatisfied owners and lost perspective buyers who prefer the last gen truck.

BTW I'm not flogging the 3rd gen but to say there isn't much buyers remorse on TW is not accurate IMHO. That's all I hear on here, oh and random dick slapping both ways.

 

You probably would like it more once you got used to it. Like how your russian bride likes you! (Jokes)

 

If you watch the Canyon video, they said the V6 version did the climb in 7:54 seconds vs 8:05 in the Taco. So the V6 is stronger and the diesel is more efficient. Either way, GM wins.
