There have been rumors that the new
M3 would get a V-8 engine, and some people pointed to the 4.4 liter
mill used in the big Beemers. Now we know. The M3 will look slicker
than we have seen from BMW from some time, and it looks as if the Bangle
Bungles of the current series have finally been ended.
To saved weight, the roof is reinforced
carbon fiber, like the M6, and the car has a lot more in common with
the M6 than you might think - except looks. You see, the V-8 is essentially
the V-10 of the M5 and M6 - you may remember that the V-10 is unusual
in have a 90 degree angle between the banks. 90 degrees is what you
need for V-8s.
The new V-8 is very compact, like the
V-10, and is actually lighter than the in-line six used in the current
M3 - the new engine weighs 445 lb (202 kg) 83 lb (38 kg) less than the
six. That is a lot. The new V-8, which develops 420hp at 8,300rpm and
400Nm of torque at 3,900rpm, is also a good deal shorter than the in-line
six. Should make the new M3 a real stunner, and worth waiting for.
Efficiency is enhanced by the use of
regenerative braking - when you are braking the alternator charges a
special battery, saving energy. A real stunner, capable of getting to
60 mph in 4.7 seconds. We'll be doing more on the M3 soon.
Slick Nissan Coupe -
Has Nissan got the Infiniti coupe right
with the Infiniti G37 Coupe, which is getting near a sports car in performance?
They have certainly tried hard, enlarging the 3.5 liter V-6 from the
350Z to 3.7 liters, and pushing power up to 330 bhp. Also, the car looks
pretty slick.
Nissan styling has always been lacklustre
- with a few notable exceptions such as the 350 Z - but this is all
changing now, and the G37 certainly looks the part, but retains a grille
that is similar to other Infiniti models - Nissan has decided that if
the Europeans retain their grilles as good trade marks, so there's should
do the same trick for Infiniti.
Overall, the G37 is a pretty slick looking
job, but leaning towards the cruiser rather that the sports car in its
lines, but pleasing nonetheless. It has double wishbone suspension and
four-wheel steering.
--and just as slick Hyundai coupe
The one fly in the ointment from Nissan's
styling is that at first glance the Hyundai concept coupe, due for production
soon looks very similar to the Infiniti G37. Is it a copy? Not likely,
as it takes too long to produce a model, but no doubt the Hyundai engineers
were inspired by the Infiniti style.
The big difference is that the Hyundai
Genesis is a four-door coupe - four-door coupes that like two-door coupes
are definitely going to be the big news in the next couple of years.
Jaguar started it with the C-XF, now comes Hyundai. There will be more.
The Hyundai has the right specification,
with double wishbone front and multi-link rear suspension, speed-sensitive
steering and a V-8 coupled to the ZF six-speed automatic. The 4.6 liter
engine is about right for the US market, and is said to develop more
than 300 bhp.
Weight distribution is said to be 53 per cent front and 47 per cent
rear, which is pretty good for a sedan of this size, but Hyundai's new
range could be hot.
Caparo gets bigger V-8
The long-awaited Caparo T1, which is
set to chance the face of the exotic car world, will now get a naturally
aspirated 3.5 liter V-8 instead of the supercharged 2.4 liter V-8. Why?
Well, there are plenty of 3.5 liter designs to base a new engine on,
thanks to the various single-seater racing classes that are now thriving.
Also, a naturally aspirated engine produces
less torque than a supercharged one, so the gearbox, final-drive and
drive shafts can all be smaller, reducing weight. The new engine will
deliver 500 bhp, the same as the original concept, and will not increase
weight.
The change of engine is one reason for
the delay in production, which should start very soon. Another reason
is the desire of the owners of the company to gain publicity to promote
the main business of supplying high-tech materials and components to
the auto industry.
