You can brush off Porsche's cosmetic makeover of the facelifted 2016 Boxsteras trivial, but you cannot say the same about the changes it has in store for the engine bay.

Earlier this year, Porsche CEO Matthias Müller confirmed the debut of the firm's new generation of horizontally opposed four-cylinder powerplants for the mid-cycle facelifts of the Boxster roadster and its sister model, the Cayman coupe.

What's still up for debate is the lineup of four-pots and whether Porsche will replace all flat-sixes or keep some of them for the regular (non-GT4) range, depending on the market.

In regards to the former, some reports say there will be two core turbo'd four-cylinder engines with displacements of 2.0-liters and 2.5-liters in at least three versions producing up to around 360 horses, while other sources add a third, 1.6-liter unit with 210 or more horses to the mix as well.

The Cayman GT4, and possibly the Boxster Spyder, will likely continue to use normally-aspirated flat-six mills.

Much like the upcoming refresh for the 911, the 2016 Boxster will receive a number of small styling tweaks, such as revised lights and bumpers, altered air intakes on the rear fenders, and different door handles on the outside, while interior updates are expected to include a new version of Porsche's infotainment system with a larger screen and a new steering wheel.

We've heard rumors that Porsche may unveil the 2016 Boxster as early as next month'Frankfurt Motor Show, but it could end up being pushed back for early next year.
 
We’ve previously reported on the small-capacity boxer four-cylinder engines coming to the junior Porsches, and in the new August 2015 issue of CAR magazine we reveal further details about the upcoming four-pots:
  • Boxster/Cayman 240bhp 2.0-litre flat four turbo
  • Boxster S/Cayman S 300bhp 2.5-litre flat four turbo
  • Boxster GTS/Cayman GTS 370bhp 2.5-litre flat four turbo

The advanced direct-injection engines are believed to make do with only one fixed-vane turbocharger, but Stuttgart is planning an e-boost electric system as a short-to-mid-term option. The new four-pots spell the end of the boxer six-cylinder in mainstream Boxsters and Caymans, although specials like the GT4 will continue with the extra cylinders, CAR understands.
[h2]When will we see the new 981.2 Boxster and Cayman twins?[/h2]Not until early 2016, according to our sources. That points to a motor show debut at Detroit or Geneva next spring, we reckon. Like the facelifted, all-turbo 911 range, due at the 20105 Frankfurt motor show, the revised two-seaters are set to receive a truckload of chip-controlled safety and convenience upgrades. But the key innovation is of course the pair of brand-new horizontally opposed four-cylinder engines. It might even be enough to warrant a new badge; we hear the 717 name being bandied around, aligning the sports cars with big brother the 911.

[h2]Cayman to be repositioned beneath Boxster[/h2]CAR understands that the 981.2 relaunch will also include the option, in some markets, to position the Cayman as the entry-level, cheaper model for the first time. The move is designed to increase awareness and boost sales; the soft-top has consistently out-sold the coupe ever since launch a decade ago. Should Porsche do this and risk annoying existing customers? Let us know in the comments below.

The facelifted Porsche Boxster will receive uprated styling and a new four-cylinder engine when it goes on sale in the UK at the start of next year.

The revamped third-generation Boxster is due to receive its global debut at the Frankfurt motor show in September. Styling changes for the reworked roadster include a revised front bumper with new air intakes, and altered light clusters. The car's interior is also expected to be upgraded, judging by the camouflaged cabin of this latest prototype.

However, the biggest change looks set to take place in the engine bay, where Porsche is set to introduce a new horizontally opposed four-cylinder powerplant as part of plans to broaden the appeal of both the Boxster and its fixed-roof sister model, the Cayman.

Already confirmed by Porsche chairman Matthias Müller, the new engine is planned to be offered alongside upgraded versions of the existing Boxster’s horizontally opposed six-cylinder engine.

"We will continue with the downsizing strategy and develop a new four-cylinder boxer engine, which will see service in the next-generation Boxster and Cayman,” Müller confirmed last year. "We will not separate ourselves from efforts to reduce CO2”.

When queried on the output of the new four-cylinder boxer engine, Müller said it would produce "up to 400ps [395bhp]”.

It's expected the new flat four-cylinder engines will support 2.0 and 2.5-litre capacities, with power outputs from 210bhp through to the 395bhp alluded to by Mueller.

The six-cylinder boxer engine used by the existing Boxster and Cayman develops 261bhp and 271bhp respectively in 2.7-litre form, with a larger 3.4-litre unit offering either 311bhp, 325bhp or 335bhp depending on the model in which it is deployed.
