Dean Slavnich test drives the new Porsche Boxster
Porsche
has never been one to follow. So, in a time when design has taken centre
stage in our industry, Porsche has decided to go against the grain with
its most important model; the new Boxster.
The biggest design change
on the new Boxster comes in the headlamp arrangement |

The standard Boxster has
a top speed of 256 km/h (159 mph) while the Boxster S model
can reach 268 km/h (166 mp/h) |

Industry gossip of late has been nearly all “Bangle this”
and “Audi grille that”. Controversial styling, it would seem,
is top of the agenda with premium brands around the globe. Not with Porsche.
There’s no whiff of flamboyant lines, angular curves or even a controversial
face on the new Boxster. No, instead it’s the engineering that’s
taken centre stage. The Boxster might appear the same but scratch the
surface and look under the skin and one will find a completely new car:
the new mid-engine roadster packs an even greater punch, has an enhanced
ride and features no less than 80 per cent of new components and parts.
The best just got better.
For example, the suspension on the new Boxster is essentially the same
as the previous model, the only difference being that where it used to
be very good, the suspension is now near perfect. Porsche engineers have
meticulously checked every detail. So, as well as there being a reduction
in weight on individual components, the new Boxster also gets a wider
track and bigger tyres and wheels, ensuring the drive becomes even
more dynamic.
The concept of having the front wheels suspended on a spring strut axle
with the separate arrangement of the longitudinal and transverse arms
has been carried over onto the new Boxster, but there have been three
significant improvements. Firstly, the front axle with a new aluminium
crossbar has been re-developed, which means that the front axle geometry
has been fully updated and serves even better in the event of a collision.
The Boxster’s crossbar has also been widened by 15mm on either side
which frees-up room to move out the axle points, allowing for the Boxster’s
track to be widened by 35mm. This all means that the Boxster’s class-leading
handling and precision capabilities have just got better, not forgetting
that the new aluminium crossbar has shaved 0.5 kilos off the total weight.
Impressive stuff.
It’s through this strategy, scrupulously fine-combing the first-generation
Boxster and looking for margins of improvement, that’s allowed the
second-generation Boxster to be a better car.
The examples continue: a hydraulic bearing replaces the former, conventional
rubber bearing connecting the longitudinal and transverse arms. This not
only enhances the driving comfort but also better soaks-up vibrations,
something that became immediately apparent as the Boxster swallowed with
ease small potholes on the Austrian roads.
The springs, dampers and anti-roll bars have all been reset to better
fit the geometry of the new Boxster’s chassis and suspension. This,
combined with the larger and wider tyres, amounts to less sway and roll.
Yet the new Boxster is not just all about components being tweaked from
the previous model. No, there are plenty ‘firsts’ as well.
The mid-engined sportscar gets a hydraulically assisted rack and pinion
steering with variable transmission. This means the new Boxster takes
corners with amazing ease. The hydraulic system also ensures a smoother
ride, especially on the straight at high speeds.
At the back end the McPherson rear axle has also undergone re-development
work to increase transverse stiffness and decrease weight. New twin-tube
dampers with a longer guide tube and larger outer tube have been used
to crank up the stiffness level, while aluminium has been freely used
to cut down on weight. The subframe is now made of pressure-cast aluminium
as is the wheel mount featuring a longer pivot lever.
Technology that once only graced the 911 Carrera also makes an appearance
in the new Boxster, like Porsche’s Active Suspension Management
(PSAM) that literally offers two suspension settings in one: a sporty
and comfortable suspension for long distances and a dynamic setting for
the racetrack.
The PSAM technology is made-up of adaptive dampers that are adjusted by
two accelerometers determining the vertical movement of the car’s
body. The technology activates firmer dampers when the dynamic mode is
selected.
There are even ceramic brake disks for those that can afford it, bringing
with them the usual list of benefits including even a faster braking response.
Along with the enhanced engineering feats comes more power: the new Boxster
packs an even greater punch. “Let me put it this way: we have sent
the Boxster to the gym in order to give the car even more muscle and strength,”
says Dr. Wendelin Wiedeking, Porsche chairman.
So the standard 2.7 litre engine, which when first launched in the Boxster
back in 1996 was only of 2.5 litre in capacity, has been reworked to now
offer more torque and power. An impressive 270 Nm (199 lb ft) of torque
kicks in around 6,000 rpm with power output coming in at 243 ps (179 kW)
at 6,200 rpm. This kind of power drives the Boxster to 100 km/h in 6.2
seconds before reaching a top speed of 256 km/h (159 mph).
Meanwhile the Boxster S has even more power on tap. The 3.2 litre engine
has been configured to now boast 284 ps (209 kW) at 6,200 rpm and a torque
curve that peaks with 320 Nm (236 lb ft) at around 6,000 rpm. The top-end
Boxster sprints to 100 km/h in only 5.5 seconds and can then gather pace
to 268 km/h (166 mph). Porsche, unlike its German cousins, does not do
speed limiters.
Plenty of changes have taken place in the two powertrains. There’s
a new and even larger air filter, a double-chamber distribution pipe with
distributor flap and a completely re-designed exhaust system.
Power is transmitted to the wheels on the new Boxster through a five-speed
gearbox, though for the Boxster S there’s a new six-speed gearbox.
Available as an option in both models is a five-speed Tiptronic S transmission.
The result of the enhanced engineering, extra power and bigger wheels
is that the Boxster has not only grown in stature but size as well. The
bulkhead at the front has been redesigned which has allowed for the gas,
brake and clutch pedals to move forward, increasing legroom and offering
greater luggage space.
It seems no stone was left unturned by Porsche engineers during the development
of the new Boxster. Along with the rest of the car, the folding roadster
roof has also been improved upon. It makes use of an extra-light magnesium
structure to not only save on weight but also to take-up less space when
folded away at the rear. It’s now also possible to open and close
the roof driving up to a speed of 50 km/h (30 mph), another first for
the Boxster.
The interior has been bettered as well. For the first time the new Boxster
comes with a steering wheel that can be adjusted not only for reach but
height as well. Leather and high quality materials are splashed everywhere,
while white LEDs add a clean and clear touch to the cabin. There are no
less than three new steering wheels on offer, a new stereo CD radio player
with Bose surround sound and extremely comfortable seats.
It’s plain to see that the new Boxster has been improved upon in
every area. Which brings me back to the design: the biggest change in
style between the new Boxster and its predecessor is that the fried-egg
headlamp look has been replaced by main headlamps that are separate to
the front light units with their integrated fog lamps. All else remains
similar.
The Porsche CEO has his own take on the design of the new Boxster. He
says: “There was no reason to make any radical changes to the design
of this car, contrary to what we see in the case of our competitors. This
is quite simply because you cannot, and of course should not, destroy
or reinvent a timeless look.”
Wiedeking adds: “The Boxster proves that once you have achieved
perfection it becomes increasingly difficult to add any new features or
make changes.”
It just goes to show that sometimes carmakers need not think outside the
design box to develop a great car. All they need to do is think inside
the engineering box.
