while these never set the world on fire, the engineering behind them in interesting to say the least.
>independent rear suspension featuring a fiberglass transverse leafspring
>Engine was the first American designed and built DOHC V6
>Said V6 was adapted from a pushrod block, leading to 5 camshafts. The crankshaft drove a chain up to the dummy camshaft in the block. The dummy camshaft then drove a cogged timing belt that drove the 4 overhead camshafts that actuated the 24 valves. Though severely detuned in production form, power output was impressive for the time, making 210 HP.

The W-body chassis underwent numerous revisions. Gen 1 cars used the fiberglass leafspring in the IRS.
Gen 1 cars:
1988-1996 Pontiac Grand Prix
1988-1996 Buick Regal
1988-1997 Oldsmobile Cutlass Supreme
1990-1994 Chevrolet Lumina.
Gen 1.5 cars are identical to gen 1 cars with the exception of the rear suspension. Gen 1.5 cars ditched the leafspring for a coilspring setup, using macpherson struts at all 4 corners. All W-body cars since used a similar rear suspension.
Gen 1.5 cars:
1995-1999 Chevrolet Monte Carlo
1995-2001 Chevrolet Lumina
Gen 2 cars were wider and had a longer wheelbase. The reason for them being wider was so Pontiac could advertise the return of the wide track Pontiacs.
Gen 2 cars:
1997-2003 Pontiac Grand Prix
1997-2004 Buick Regal
1997-2005 Buick Century
1998-2002 Oldsmobile Intrigue
2000-2005 Chevrolet Monte Carlo
2000-2005 Chevrolet Impala.
Gen 3 cars weren't supposed to exist. They were supposed to be replaced by an extended wheelbase epsilon platform, but thr program stalled so the W-body was updated again into the gen 3 cars.
Gen 3 cars:
2004-2008 Pontiac Grand Prix
2005-2009 Buick LaCrosse (sold as the Buick Allure in Canada)
2006-2007 Chevrolet Monte Carlo
2006-2015 Chevrolet Impala (2013-2015 cars were only sold to fleets like taxi's and rentals)
Pic related. A gen 1.5 Monte Carlo.

Does explaining how an engine works makes it interesting? It's just an another american unreliable POS.
>>15444088
This. Finally someone who understands!
This car was absolutely built with one thing in mind. Speed. It was shaped after numerous hours in the wind tunnel and numerous sketches. It may look bloated but everything in this car makes absolute sense. But I like the way how it actually is.
Even though VW did a publicity stunt with this car and lost a ship-load of money on each car they sold, they gained a lot of knowledge and expertise that no other car company in the world has ever gained. It's truly a feat in engineering. Chiron is just a greater feat to the Veyron and the CEO of Bugatti as already said that they will strive for perfection and speed. I love it.

>>15446016
You know I'm just going to throw this out there for mouthbreathers like yourself. Maybe GM didn't see the need to spend time and money to R&D a 350 horse v6 in midpriced FWD coupes and sedans that had to meet epa regs and be built in the 80-90s.
>>15443939
Those were a pain to work on. Half shaft has to come out just to replace the alternator.

another marvel of engineering right here
>>15443936
friend has a 1994 pontiac grand prix with the 3.1 v6 that sounded like a cammed v8, beat the shit out of it and took it over bumps 40+ mph and hooned the complete shit out of it, then manji'd into a curb in the rain and bent the driverside rear suspension all up, probably will still start up and run, it's been sitting for a year.
Do I win?

No, then they would have made a light-weight car instead of a 2-ton saloon.

and numerous sketches.
What are you even trying to say? Other cars are just built haphazardly?

Do cars have to make sense in the US, or does Detroit just build whatever they feel like?
>>15444295
>It was shaped after numerous hours in the wind tunnel
Actually, the biggest problem with the Veyron is that it was designed, in 1999, before it was engineered. It was the 250mph aerodynamics and cooling that meant it took 6 years to develop the thing. Just look at the Chiron's gaping anus for function over form.
TMYK
>>15446300
Detroit builds what will sell. If the owner wanted a smaller GM coupe in '95 they bought a J-body. Anytime you want to own, maintain, make a profit out of a automible company just step up anon. Otherwise don't pretend you know better.

No. Also your crummy unit wasn't even reused in the Pagani Zonda.
First AWD car
and some other innovative stuff
Viper and the AC Cobra that inspired it.
>large engine
>small coupe built entirely around it to handle said engine
>engine block came from a truck so it was very cost effective for the performance it delivered
>engine weighed nearly 700 lbs or more and the car was still a performance success and weighed around the same if not less than its rivals with smaller engines
The Supra (as far as i know) could never race with its 2J engine because it was too heavy and opted instead for one of Toyota's 4 cylinders. The viper's engine was just as heavy as the 2J or even heavier and it was still competitive in motor-sports. Even to this day this combination so far has remained a match made in heaven.
>>15446538
That's because the Toyota is an actual car you can actually drive, and the Viper has nothing else in it other than its hurr cubic inches ship motor.
the Multijet
>>15446012
Only real niggas will appreciate this.
>>15446552
many forget that the supra is a grand tourer, not a sportscar
>>15446538
Not to nitpick but the Ram and Viper V10s where designed independently. The only similarity was the number of cylinders and the displacement.

>>15446016
What part of severely detuned did you not understand? Production ready prototypes of the engine made 280 HP. So why did they detune it to 200-215 HP? So the automatic transmissions would survive behind the engine. They couldn't get a FWD automatic capable of handling the V6's torque. There was a manual option available (made specifically for the engine by Getrag and had no trouble taking the power) but it was discontinued due to poor sales. Out of 40,000 3.4 powered Lumina Z34's made per year, around 3000 of them were manuals. Manuals were available from 1991-1993. Even with the manual, the engine was detuned because GM management.
>>15447192
200mph in 1970? did that make this the fastest production car in the world at the time? or does it even count as a "production car" i remember hearing Clarkson say that the F40 in 1987 was the first car to hit 200mph. does that mean this was the fastest production car in the world until that moment or were there other cars that eventually hit 200mph after this?
>>15447289
The 200 MPH was achieved during a NASCAR race. The cars were modified for racing. Street cars were never tested to 200 MPH.
The Ferrari F40 is stil the first production car capable of 200 MPH on the street, until someone can take a production Daytona or Superbird and test it on a track.
>>15447289

They are literally inferior. Men are overall better... I mean, it's the fact. We're stronger. More intelligent. Just to name a couple off the top of my head.
>>15447374
That's the average speed over the lap BTW, that's how they measure it in oval.

>>15448102
>>15448181
Because it's retarded. 40% of women are "more intelligent" than the majority of men, including you. Treating them all differently instead of just looking at their actual performance is a huge waste of both male and female human capital.

Not that anon, but you know that car has spent exponentially more time in the wind tunnel than any other production car ever, save the McLaren F1.
The car itself was reasonably well designed, but the R26B is just glorious.
>>15449106
The difference between a two plug engine (standard) and a 3 plug. This allows fuel to be burnt more efficiently by reducing """"squish"""" which leaves some fuel unburnt.
>>15448973
Yes I know, but all modern cars still spend "numerous hours". Which is what I remarked on.
Also "exponentially" doesn't mean "a lot" stop using words you don't know

Because they aren't increasing the efficiency of the engine by any sort of engineering, they just saw unburnt fuel and added another spark plug. Then another one when it still wasn't burning clean.

the man has a point. there isnt really something distinguishing the GT from the rest of the supercars out there. sure the rear archs are different but all of them have their own look. the lambos are edgy, the 911s have their charachteristic shape. the engine isnt really something special either

It's great because it's a Ford performance car. Their highest performance car ever made at that. Look at the GT350 in their lineup and see the performance. Now imagine a car with more than 7 times the budget. It's going to be insane.
>>15443909
This car may be a design masterpiece, but it was poorly engineered and made. Hard to get in, you coudn't open any windows, it was made so badly that when one guy tried to restore one of those he had to have it done at workshop which specialized in restoring italian supercars, because it was as badly fitted as those.

>buttresses
That's a design decision retard. This thread is about engineering
>wide open rear end
What do you even mean by this? It looks like tons of other supercars. Also how the fuck would that even be "engineering masterpiece"? The reason it's open is because they can't cool it properly otherwise

>>15447286
not the guy you have been mentally jousting with, but consider...
All GM cars have to be able to hit 250k miles as a daily driver. I believe parts must be available for a min of 15 yrs. These corp mandates differ from what ferarri, lambo or other boutique auto makers have to abide by. This is why GM makes corvettes and not 100 car runs of exotic tech.
GMs standard LS/LT series of engines can make a minimum of 600 hp/600 ftlbs with just a heads and cam swap. Start playing with the bottom end and adding forced induction and the sky is the limit. The tech is most certainly there. Detuning gives engine reliability to meet the internal mandate.

Fun fact: the Volvo 960 / V/S90 from 1995 util the end 1998 also had a setup with independet rear suspension and a transverse fibreglass leaf spring.
I had a 1998 without the self-adjusting rear shocks, it sagged very low in the back when you put a bunch of heavy stuff in it, or towed things. It probably worked better with the Nivomatic shocks.
