A brand-new Z4 and the return of the 8-series
are nailed on certainties, and that mid-engined supercar plan isn’t going away
either. By Georg Kacher
Think BMW has given up on sports cars?
Think
again. Development is intensifying on a two-seat roadster to replace the Z4,
and a flagship coupe reviving the 8-series badge won’t be far behind. Finally,
and ultimately, a mid-engines super car is proposed for 2019. That’s one hell of
a triple whammy.
Today’s
Z4 roadster quietly passed into the automotive afterlife this summer, when
production ceased at the Regensburg factory in Bavaria. Its replacement will
hit the market in 2018.
Its origin has long been public: the sports
car is being developed in a joint venture with Toyota, although the Japanese
have let the Germans run the project. Toyota’s prize will be the rebirth of an
all-new Supra coupe, while BMW gets a box-fresh two-seat roadster code-named
G29.
Today’s
snug cabin will make way for a more spacious cockpit, thanks to optimal
packaging rather than a massive growth spurt, which would imperil the
engineers’ obsession with paring back weight. The headline news is that the
current folding hardtop makes way for a classic canvas roof, which will lower
the center of gravity and do less damage to boot space when retracted.
Engines
are mounted north-south in that long nose, sending power to the rear wheels.
The top-of-the-line Z4M will run a 3.0-litre straight-six, with turbocharging
cranking up peak power to 444bhp – the same as in an M4 Competition Pack. That will be good for a 0-62mph sprint in well
under 5.0sec. BMW will broaden the range, and reduce its CO2 footprint, with
four-cylinder petrol engines too – no word whether diesel power will make its
Z4 debut.
Hybrid assistance definitely will not.
Hybrid assistance definitely will not.
Although
engineers have been spotted testing a fixed-head version of the BMW, the Toyota
agreement currently reserves the coupe body style for the Supra. Unlike the
GT86/Subaru BRZ twins, the BMW and Toyota will run different engines: the Supra gets a twin-turbo V6 sourced from
Japan. Both Z4 and Supra will be assembled on the same line, in a BMW plant. It’s
an economic necessity, just like the JV itself, given the dwindling number of
sports car sales globally.
8-series. The next big BMW thing
Hot
on the wheels of the Z4 is the 8-series. If you’re wondering where is the gran tourism
sister car to next year’s new 5-series, this is it. Having turned 8-series into
6-series for the 2003 and 2011 generations, the 6-series will now revert to
8-series for the 2018/19 edition. Got that?
That
means the 8-series will head upmarket, towards the Mercedes-Benz S500 coupe
which costs from just under $100k. Two body styles are confirmed, two-door coupe
and cabriolet.
The
approach mirrors that of the 7-series compared with an S-class limousine:
create a lighter and much sportier car. Also set to apply is a description you
couldn’t level at the last two 6-series: a proper four-seat cabin.
The
8-series will be one of the last BMW models to use the current CLAR
architecture. That’s the components set which underpins the latest 5- and
7-series among others, employing a multi-material construction to keep down
weight. Up to 200kg could go, which would be a massive improvement on today’s
big unit which exceeds two tones with larger capacity engines. Air suspension
is a given, rear-wheel steering to sharpen turn-in is in the plan too.
The
core engine will be the 4.0-litre V8, topping 500bhp in base turbocharged
guise, and reaching 650bhp for the M model. The entry-level model is the 444bhp
six again, plug-in hybrid electric assistance may be coupled with a four or a
six, and there’s room in the engine bay for the V12, if deemed necessary.
The
bad news is that BMW’s supervisory board chairman Norbert Reithofer, the
mastermind behind Project i when he was running the management board, conceived
the 6-series replacement as a lightweight, compact, true 911 fighter. It’s a
shame that car has ultimately morphed into an S-class coupe rival but news of
the third salvo in BMW’s sports car assault could provide ample consolation.
The supercar.
On its way in 2019?
As
reported in CAR, BMW and McLaren have been in on-off discussions about a
joint supercar project for the best part of two years. BMW’s ideal is
to piggyback
the carbon fiber monocoque for the 650S replacement. The trouble is that
McLaren is charging ahead with its new supercar, and BMW is in danger of
being
left behind. The world have already locked in a hybrid drive train
mixing
turbocharged V6 petrol power with an electric boost; a classic BMW
straight-six
is now a non-starter.
And the less BMW DNA is visible in the
proposed supercar, the more nervous Munich executives become: that’s why they
insisted on an active role in the JV with Toyota. There is a fallback position:
BMW could couple the mid-engined supercar with the i8 replacement but that car
might not see the light of day until 2022.
BMW
would be seeking at least 650bhp for its supercar, and the capability for the
chassis to handle all-electric power too. That’s because the next-generation i8
will not be a hybrid but a pure electric performance car, with higher output
batteries giving a usable 300-mile range. Propulsion comes from three
high-revving (up to 25,000rpm) e-motors developed in-house which produce a
combined 700bhp. The triplets dish up more instant torque than any set of tires
can handle, so it’ll have to be precisely metered. Also part of the package:
four-wheel drive, four-wheel steering and torque vectoring, as well as a
robotized suspension that can look ahead, sources say.
But
what happens next? Some in BMW are having an existential crisis, wondering what
electrification and autonomy mean for the ultimate driving machine. The
progressive faction believes the 7-series and 8-series will not be radical
enough come the next decade, and argue the top end of the portfolio needs to be
reinvented, that Modern Premium must be revolutionary in more ways than one,
that BEVs will be the next big thing, and sooner than we think.
While
design has recently internally shown its first vision of the next 7-series due
in 2022, the avant-garde wing demands a more courageous flagship based on a
bespoke zero-emission architecture, which will eventually take over from the
conservative combustion engine-based concept. Sounds plausible but the
financial controllers were stung by the multi-billion Project i investment and
are now reluctant to take risks. Whoever wins this ideological battle will
steer the future of BMW and its product portfolio, including the shape of the
next-generation supercar and many more besides.
