Looks like a pretty mean truck, with an 8.0 liter engine that makes 300 horsepower and 600lbs.-ft of torque.

That thing is BADASS! If they come out with a non-dual form with that diesel, the 5.7 will be for $ale...too bad its just a concept right now (and probably will be for a while since they had problems loading that 8.0L in there...)

the word is 2012 for the diesel. After it comes out, I heard from a toyota guy that a diesel hybrid will be in the worx. upwards of 30mpg!!!

looks like there is a 5 leaf pack under the rear?

also, they've got 295/60/22.5 tires....Alcoa rims!

Brushed Aluminum front bumper.

Cool over cab lights... might be driving, fog and running light combined.

Hopefully, the production model will be a tad thinner in the rear.... I'd like to see the rear wheel wells taper off towards the tailgate so that the taillights are flush against the tailgate.

SEMA 2007: Tundra Dually Diesel

Are those power figures from Toyota (300/600)? Pickuptruck.com has the numbers at 220 hp, 520 ft*lb. 8.0 liter and 1500 pounds. . . .that's a big motor. Surly Hino has a smaller motor that could work for a 1 ton Tundra. Currently, the largest domestic diesel is 6.7 liters (6.6 liter and 6.4 liter as well). All of those are over 340 hp, and over 650 ft*lb.

I find it funny, Toyota says it's keeping the powertrain "all in the family", yet the Allison Transmission it uses is from GM. . . . .

But GM no longer owns Allison. Either way, it is "outside" of the company.

GM owned Allison Transmissions for 90+ years, iirc. . . . I'd say it's a GM transmission, despite them selling Allison this year. . . .

Why not just use the Hindo's medium duty transmission (same place they got the rearend, brakes, and engine)? Just seems odd that they opted for an Allison. . . .

Just think...in 2012 Diesel Fuel will be about $12.00 a gallon

Are you referring to the concept diesel? It doesn't use an Allison, it uses an Eaton 5 speed manual. (still "outside the company" though)
Edmunds IL has the engine rated at 256hp and 745lb-ft.

8.0l six cylinder producing only 300 hp and 600 lb-ft?
thats a giant slow diesel guzzling thing
im sorry...im really disappointed in toyota...thought they would come up with the real deal...a cat diesel or something better

Surely they can tune for more power. There's no doubt about that.

But I'd much rather see an engine with more than 6 cylinders, especially for heavy-duty related work

***mhadden*** · 10-31-2007, 07:54 AM

I agree...fewer cylinders = less cost associated with repairs. Unfortunately, the less cylinders, the less power and torque

I'm suprised to see a smaller diesel wasn't put in there, but hey, I'll take any diesel that Toyota offers

well...thats not necessarily true...dodge's cummins diesel is a 6 cylinder but produces the same amount of torque and hp as ford's powerstroke and only 10 less lbs-ft than GM's duramax diesels, and produces peak torque at a lower rpm

Good call...I meant to say "usually means less HP/torque", but this is an instance where its not true
