Goodbye,
V-8s. Maybe This Time, for Good
by

V-8s are on
the way out again.
The first mass
extinction occurred circa late 1970s/early 80s as a
result of the first round of the government fuel economy edicts
known by the acronym, CAFE or Corporate Average Fuel Economy.
CAFE mandated that cars (but not trucks) achieve an average
of at least 22.5 MPG or else the automakers who continued to build
such wastrels would be hit with gas guzzler fines, which
they in turn would pass on to the consumer. This made the formerly
commonplace full-frame, rear-drive (and V-8 powered) family car
economically impossible at least, given the technology of
the late 70s era.
So, they
mostly disappeared.
V-8s (and mass-market
large cars) made a comeback in the 90s and through to the
present day as technology especially fuel injection and overdrive
transmissions made it possible to make the 22.5 MPG CAFE
cut. Or at least, come close enough so that any gas guzzler
fines were economically manageable. Even something as stunningly,
obstreperously powerful as a 2012 Cadillac CTS-V packing
a 6.2 liter, 556 hp V-8 can manage 19 MPG on the highway,
thanks to the efficiency improvements of the past 20-something years.
But no technology
in existence today or on the horizon will get the
CTS-V or anything else with a V-8 under its hood close to the new
CAFE mandatory minimum of 35.5 MPG, which goes into effect come
2016. That means in all likelihood that V-8 powered
cars are about to go away again, this time probably for good.
In fact, the
die-off is already happening.
The 2013 Jaguar
XF which since its introduction in 2009 has always come with
nothing less than a five liter V-8 will come standard with
a 2.0 liter four next year. The optional engine will be a
six of about 3 liters displacement.
Lexus has dropped
the V-8 as an available upgrade in the 2013 GS series sport sedan,
which is now V-6 (and hybrid) powered only. Audi has retired the
A8?s 4.2 liter V-8, replacing it with a V-6.
Mercedes is
going to introduce a new hybrid version of the E-Class for 2013.
The V-8 version of the E will still be offered, but with a starting
price of almost $60,000 it will not be a mass-market car.
V-8s are becoming
engines for the rich-only. More on this in a minute.
Even sixes
are in peril. BMW has shunted the formerly standard inline six in
both the 3 and 5 Series, in favor of a new (twin-turbocharged) four.
Its a
clear trend and the fact that we can see it developing on
the luxury-performance end of the automotive spectrum is the proverbial
canary in the coal mine as regards more modestly priced, large-engined
cars such as the Chrysler 300 and probably much-anticipated
but likely to be very short-lived models like the 2014 Chevy SS
sedan.
If Jaguar,
BMW, Audi and Lexus can no longer afford to build V-8 cars (at least,
in large numbers, as mass-market models) then its a dead certainty
GM and Ford and Chrysler wont be able to, either.
That includes
trucks, incidentally.
The new CAFE
standard 35.5 MPG, average doesnt apply just
to passenger cars, as the original 22.5 MPG CAFE standard did. Everything
short of commercial vehicles is now lumped together in the same
category. There is no more light truck loophole
the loophole that made it possible, back in the 90s, for the
car companies to do an end-run around CAFE for passenger cars
by putting big engines into bigger vehicles that could be categorized
as light trucks and which they called SUVs.
