Lol.... 25% of supras i see on craigslist and ebay say V6... i just laugh.

Is it cheaper for manufacturers to construct FWD vehicles? why are they building so many vehicles with front wheel drive??? even some "suvs" are front wheel drive... i just think thats pathetic.

I just think I6 is the most ideal choice... ive grown onto supras so much i dont even THINK of owning any other car.. just spending 50,000$ to make my supra godly. lol.i just see so much potential in it..

Efficient packaging, many consumers demand FWD because they are more comfortable driving them in bad weather, etc.

Many SUV's have started to be based on car chassis rather than truck bases. This causes a shift to FWD rather than RWD. Most SUV's sold are A/4WD variants - the 2wd intended to bring up the lower end of the price spectrum and/or for regions where inclement weather is not a primary concern of the buyer.

The fact that there are so many SUV's is pretty pathetic to me, not that some are available in more fuel efficient (FWD) guise. I don't find anything wrong with v6's or with 2wd SUV's - there are plenty of things to choose from if they don't float your boat.

Also mainly because most truck/big car motors are based on existing technology. When all the companys started with the smaller motors and smaller cars in the 80s and 90s, there inline motors were gone. So now in modern times, the "existing technology" is lacking any inline designs. At least GM brought one back and BMW never stopped. I really dont have anything against v6s, Just they dont sound good lud. Other than that i dont know what all the fuss is. Just grab a supra, rwd lexus, 3 or 5 series beemer, or a wrangler/tj/cj. They come in all types and price ranges! But then again, I hate 99% of new car designs, so maybe thats why i dont care what motors they use.

Its market hype, fuel economy, and the fact that nobody cares. The dealers dont even know the difference. One of them told me the cobalt was rear or AWD, because i told him thats what i was looking for but i couldnt afford a corvette. Everyone thinks FWD its safer. FWD is slightly better on gas, slightly lighter, and allows more interior room because of the lack of driveshaft, rear diff, smaller engine bay, etc. The day of mass sports car sales is over. There was a nice boom in the early 80s till the mid 90s that we have to feed off of with many cheap/affordable and nicely maintained supras, camaros, mustangs, mr2s, rx7s, etc. But future generations will have no such luck!

The Suzuki Verona has a FWD Inline 6 :)

Wow! I didn't think anybody knew about these cars. We used to have an 05 Verona. My wife wanted an SUV so we traded it. It has a 2.5 L inline six mounted transversely. I loved the car. It was an extremely smooth running car. It only had 155hp but it was pretty torquey and did alright in the get up and go department. Suzuki had a lot of issues with the engine/transmission management system and they discontinued the car in 06. I wouldn't mind finding one for a DD.

Good job Tanya, you never cease to amaze me with the auto knowledge.:icon_bigg

GM still makes an inline 6. Never driven one tho. And VW has those crooked straight 6s, the VR6. Its like a skinny v6, but with one head. So i would consider it a straight block. And they now have the 2.5 inline 5. Both are pretty cool sounding motors. Dunno if it was mentioned but volvo makes FWD straight 6 cars. They have it for a bigger crumple zone.

It's the 4.2L Atlas I6 from GM that I posted about earlier in this thread.

Some of you guys don't bother to read, do you? :sarcasm:

90 degree V6 = suck. 60 degree V6 = just as smooth as an I6

There are a few inherently smooth designs out there.

Top of the list for piston engines in vehicles that I know of is the I-6. The movement of the pistons and crankshaft naturally counter balances, so the engine is smoother, requires no counter shaft balance system and is narrow, so you have room on either side for things like intake and exhaust.

Many companies have produced, or still produce I-6 engines. BMW is quite proud of that fact. Toyota in the USDM had the 2JZ in VVTi form in the IS300, but now has gone to a more powerful, and smaller package V6 for it's RWD platform cars.

As noted, this allows for lower hood heights (Untill the pedestrian impact standard for the EU came into effect...) Also shorter front fenders and hoods. (This can help keep overall vehicle length down, and make more room for passengers etc.)

Most SUV's on unitized a chassis started off as passenger cars/vans. An exception is the Jeep Cherokee. They were built as uni-body SUV's from the start. (But really are just tall station wagons..) Common "SUV" or "Trucks" even now are just a Mini Van chassis with attitude. Examples would be the Ridgeline, Pilot, MDX, Arcadia clones, Escape clones and Hundai Santa Fe clones are all either passenger car or van floorpans with slightly different suspensions and drivetrain options. (The Arcadia is built specificly for this, but is still passenger car based v/s the body on frame design of a real Suburban for example.)

GM was playing around with the I-6 they produce for the Trailblazer clones. It can be punched out to 5.0L, and with turbo(s) and some other mods, is a very capable motor. Down under, Ford makes a turbo I-6 in a RWD sedan too, but the USDM has none of the cool cars from around the globe in many cases. (The GTO was a re-baked Holden, the GM supplier down under too.... RWD V8 powered family sedans... why not here? Because some bean counter thinks we will not buy them.)

And the government is involved in fuel economy crazyness.. Called CAFE.. Thus the reason you see so many trucks and SUV's... Americans want big, RWD and powerful vehicles just as much as anyone, but to get them past the CAFE standards, they package them as Surburbans and Avalanches..

Like that? Keep voting Liberal/Socialist... and you will get even more laws forcing you to buy fuel cars.. smaller, lighter and less room... Yay Socialist ideals! NOT.

How about my A8? It's "quattro" system works great.. (We have the snow and ice here to prove it.)

Best used car deal of the century.
V8 power. (Only 300 if you get the older one like mine, but they come in versions up to 360hp in the S8 version.)

AWD system that is very good at spreading the power around as you need it, yet does not feel like a FWD car/vehicle.

Great design. (Matter of taste, but I think they are the best looking classic sedan of any current design out there.)

Awesome interior and gauge package. Pretty much, most of the new cars/vehicles have copied the Audi interiors in many ways.
(Sit in a new Suburban.. Can you say A6 ladies and gentlemen...?)

The only down side is the ZF transmissions. They are "lifetime" and they must have the fluid changed out about every 40k if you really want them to survive a lifetime. The good news is, rebuilding the trans is only about 2500.00 and it's stronger than stock when done. (Bendix makes a kit for this trans that has better friction materials and design. Also switch over to Redline trans fluid, add a external filter and larger air to oil cooler for very long life, and better performance.)

Besides, you should see the face of the guy in the Mustang when you kick his ass in your big sedan from the stoplight! LOL It's priceless. :)

The 4 power, heated leather seats are not a bad thing either. Neither is the Alcantera headliner and door trim, or the Solar panel moon roof that keeps the battery charged, and runs a fan in the summer to keep the interior cool as the outside temp. In the winter, you can warm the interior for up to 45 min at a time when the engine is off.. there is a pump that cycles coolant over the motor through the heater core, and keeps car warm while you go inside shopping for example...

And the best part? I can get 28mpg at 83mph on flat ground, no wind. Not too shabby at all. (I've averaged a best of 24.7mpg on more than a few 800mile trips, and I can live with that combo of fuel and power.)

Oh, and the body is all Aluminum. Most of the suspension parts are as well. No rust issues, and I think the door panels are pretty thick, it seems to resist door dings pretty well.

I'll buy another one if this one ever dies, and I don't decide to put another motor/trans into it... :) (Can anyone say sleeper RS6 motor into the A8... LOL That would be very fun indeed.)

V6 has 4 main caps while an I6 has 7...

V6 center rod journal is splayed causing a weak part in the crank

Usually used because of smaller packaging (easier on assembly line, larger crumple zones, everything else that's been said in this thread).

I6 advantages is simpler exhaust and intake, smootness and durability...

BMW is the largest user of the engine design at the moment, and for good reason (and also a readon I like the body lines of their cars)

No Boxer love? :sarcasm:

Supra, straight 6's, w/e else people say is supreme in regards to the Supra... It's not the end-all-be-all. Get out and live a little, you may find the next thing to get off on.
