Here at Autoline After Hours we pride ourselves on tracking down the all-important "gurus of go" in the automotive industry. Well, dang if we ain't lassoed another ...
Thank the Lord that the Germans and the Japanese are in the mix for
building testosterone into vehicles. If these men were left solely to to
decide what we would drive they would produce bigger crap than our big
three make now. That GM man is sellout to emerging China. That is where
America's #1 Automaker is placing their future. If their ilk were visible
on a sidewalk in Livonia I would be tempted to have a "seizure" at an
opportune moment. These screws have sold off all of Delphi. It's all over.
Mexico is positioning to take North American manufacturing. Largest
Auto-park assemblies under construction currently in Mexican states.
Fkked by Ford and GM. Wait and see for Italian owned Chrysler.
Guarantee new 'vette owners will be trying to get rid of AFM as soon as
possible. I ended up really hating AFM/DoD on my Pontiac G8. When the motor
transitioned out of V4 mode, there was a low frequency vibration/noise & it
was sluggish to react to throttle input. I won't even mention the horrible
collapsible lifters that clatter like crazy on start up! I got so
aggravated about AFM & lousy transmission calibration that I got an ECM/TCM
tune that also turned off AFM. Didn't even lose any mpg!
Note the comment "more cylinders for deactivation" at 37:02 ... a V10? V12?
Seems like their implementation of AFM uses the collapsible lifters, which
means the engine is limited in high rpm applications. I'd much rather a
"taller" engine, set lower in the chassis, with overhead cams, roller
rockers and high rpm, with say 8, 10 or 12 cylinders and developing the
kind of hp that Ferrari and Lambo are producing in the F12 and Aventador.
Still, for today, the C7 and LT1 are both impressive.
You do realize that most modern performance NA engines hit 85-95% torque
before 2000rpm and KEEP climbing to max from there.Meanwhile almost all
Turbo engines trail off after hitting their max torque. NA powered cars of
similar power to a Turbo car always finish the 1/4mi at a higher top speed,
even if the turbo car finishes first. Also fat lot of good it does to have
heaps of torque and you spin it away because it comes on too fast.
Don't buy the argument about not making the 'vette E85 compatible. If it is
less efficient & people don't use it that much, why is the new truck going
to be compatible? Does GM not understand the Corvette owner demographic? A
lot of corvette owners are hotrodders & they don't buy them for economy.
There is a significant bump in hp over gasoline so of course there would be
interest in E85 compatibility!
Since the LT1 Specs have NOT been official released yet, Jordan Lee has
said the LT1 was the better engine (Take that with a grain of salt), and GM
"Small Blocks" have lots of low end torque and long power bands (historical
fact), you really can not make a judgement for or against the LT1.
Great show! I have a 2004 LS1 powered GTO with 130,000 miles on it. It runs
as strong and smooth as when it had 20,000... He's right if you just change
the oil on than every 5 to 7,000 miles they are bulletproof!
I really wanted to ask about the 3800 series V6. Since that was also OHV
and one of the best engines of the 1980s and 90s, why GM did not just keep
to the and make a next generation of that engine?
you are correct, this is really fantastic. the thing is, my spouse is
getting paid monthly for doing some surveys and browsing sites. if you
wanna try just try now: bit.ly/119Fslq?=wyrjz
Great show! - the LT1 sure sounds fantastic (even though I think the
cylinder deactivation is a bit of a cliche and extraneous, especially in an
application like the corvette)!
They can talk horsepower all day long, but it's still in way higher rpm
ranges. People want low rpm torque with a long flat band. The BMW M5 has
peak torque at 1200 rpm!
Cadenza is a beautiful name, Peter! Cerato, Optima, Cadenza, Quoris... all
are kinda Italian. Way better than K2, K5, K7 and K9 as called in other
countries.
