Porsche’s
tradition of favouring cautious evolutionary adjustments over revolutionary
changes is strongly reflected in the new Boxster. Pictured here officially
for the first time is Zuffenhausen’s new mid-engined rival to the
Audi TT, BMWZ4 and Mercedes SLK.
Despite its familiar appearance, Porsche claims the second-generation
Boxster, codenamed 987, is effectively a brand-new car. Up to 80 per cent
of its components have either been heavily revised or completely replaced,
although company officials admit many of the first model’s crucial
hard points have been carried over.
The base Boxster will run a 237bhp 2.7-litre version of the venerable
flat-six engine while the sportier Boxster S gets a 276bhp 3.2-litre unit.
The exterior resembles the first-generation Boxster, launched in 1996,
but every body panel has been altered. At the front there are large air
ducts and the leading corners of the bonnet are rounded off. Oval headlamps
replace the familiar teardrop-shaped units — a move Porsche hopes
will silence critics who say the Boxster looks too similar to the 911.
The tail-lamps are more angular than before and wrap further around. The
central exhaust has been retained. Refinements in the design of the underbody
have reduced the drag co-efficient from 0.31 to 0.29.
Both versions of Porsche’s water-cooled, four-valve-per-cylinder,
flat-six engine, have received revisions to the intake manifold, combustion
chambers and exhaust system. The revised engines are mated to an upgraded
five-speed manual gearbox in the Boxster and a new Getrag-engineered six-speed
manual in the S. The existing five-speed Tiptronic automatic from ZF is
carried over without any major changes, although it is expected to be
replaced by a new dual-clutch arrangement similar to VW’s DSG within
two years.
With the added output comes mildly sharper performance. Porsche claims
0-100kph in 6.2sec and a top speed of 254kph. The 3.2 manages 0-100 in
5.5sec and runs to 267kph.With its own factories in Germany running at
full capacity right now, Porsche has once again turned to production specialist
Valmet to assemble the new Boxster at its plant in Uusikaupunki, Finland.
