Turbo 4’s Crank it Up
– It’s all about the numbers with Porsche’s updated Boxster, now known as the 718 Boxster and for the first time sporting four-cylinder engines.
There’s 25kW more power, up to 100Nm more torque, and fuel economy improvements of between 10.0 and 12.7 percent for this major refresh of the 981 Boxster that arrived in 2012.
It’s also more expensive than ever, with price hikes of up to $12,300.
The facelifted Boxster maintains its mid-engine, rear-drive layout but eschews 911-derived six-cylinder engines for a new family of horizontally opposed four-cylinder turbos.
The new engines – a 2.0-litre for the 718 Boxster and a 2.5-litre for the 718 Boxster S – are related to the 3.0-litre six-cylinder twin turbo in the recently updated 911.
However the new 718 Boxsters only use one turbo each, predominantly because a twin-turbo setup would have required the development of a bulkier exhaust system that would mean the end of the Boxster’s boot, which sits behind the mid-mounted engine and gives the convertible best in class luggage capacity.
In the 718 Boxster it is a regular turbo, while in the 718 Boxster S it uses the same variable geometry turbine technology employed in the flagship 911 Turbo (such VTG turbos are common in diesel engines but they’re only used by Porsche and the upcoming Mazda CX-9 in petrol applications).
Peak outputs for the 718 Boxster are 220kW and 380Nm for a claimed 0-100km/h time of 4.7 seconds when fitted with the seven-speed PDK dual-clutch auto transmission. That’s the biggest performance jump in the Boxster’s 20-year history, bringing genuine sports car performance to a car that once was more about the looks and handling than the go.
The Boxster S steps that up to 257kW and 420Nm for a 0-100km/h as low as 4.2 seconds, bringing it tantalising close to the hero of the Porsche lineup, the 911.
While it rides on the same basic platform as the previous car, Porsche has retuned the suspension and fitted more powerful brakes. The steering is now 10 percent sharper, while the optional Porsche Active Suspension Management (PASM) system lowers the ride by up to 20mm in the 718 Boxster S (10mm in the 718 Boxster).
A six-speed manual is standard, while the seven-speed dual clutch auto costs extra, bringing a Sport Response button as part of the optional Sport Chrono pack. Sport Response pre-charges the turbo and gearbox for more instant response, such as when overtaking.
Porsche has also redesigned the Boxster for the 718, with slightly sharper lines and a wider stance at the rear. Only the bootlid, windscreen and folding soft-top carry over from the outgoing Boxster.
Inside the dash has been restyled and there is a new colour touchscreen with Apple CarPlay (but no Android Auto).
As part of th
e Boxster update are significantly updated prices. The entry-level Boxster increased $8400 to $113,100, while the Boxster S has jumped $12,300 to $143,400.
Porsche charges $4990 for the PDK auto transmission, however with the base Boxster it only costs customers $1333 extra because of the controversial luxury car tax rules; because the base Boxster auto slips in under the arbitrary 7.0L/100km fuel use figure its LCT threshold applies from $75,375, whereas the manual has the 33 percent tax applied from $63,184.
The new 718 Boxster arrives in Australia mid-2016.
