2017 Porsche Boxster S Manual Tested: You Won’t Miss the Six

That subtle background noise you hear isn’t just the ticking of four cylinders exactly where six formerly lived. It is the gnashing of teeth over the reality that Porsche downsized cylinder count and piston displacement to a mere two.five liters for the top, S edition of the 2017 718 Boxster. Our anxiousness centers on the move by Porsche—along with virtually every other auto manufacturer—from organic aspiration to smaller sized, theoretically more efficient, boosted induction. In case you’ve been napping, turbocharging is how makers keep functionality whilst diminishing the amount of fuel consumed and the CO2 spewing from their tailpipes.

Turbos, Then and Now

This is hardly Porsche’s first trip by means of turbo valley. Fans of the brand still revere the legendary 911 Turbo bestowed upon wide-eyed enthusiasts 41 years ago. What that rear-engined bundle of turbo lag lacked in basic drivability, it more than created up in excitement when the enhance kicked in. A handful of fenders bent in those early days combined with numerous turbocharging lessons discovered over the years culminate in what is right now a complete loved ones of twin-turbo 911 models, plus single-turbo 718 Boxsters and Caymans that arrived at dealers this summer. To celebrate the occasion, Porsche revived one particular of its most illustrious model codes for the fourth-generation Boxster/Cayman. All through the late 1950s and early ’60s, the Rennsport department’s endurance racers, hill-climbers, and Formula 1 and two single-seaters all have been 718s.

Turbocharging is one of the 20th century’s most substantial engine advancements. Swiss engineer Alfred Buchi earned the seminal patent in 1905 in 1918, GE’s Sanford Moss demonstrated how effectively this device could replace the power lost to altitude at Pikes Peak. By World War II, turbo tech was a single of America’s most important strategic assets. Chevrolet and Oldsmobile introduced the first turbocharged automobiles in 1962.

Operational theory hasn’t changed. Energy generally dumped to the atmosphere out the exhaust pipe as an alternative spins a turbine wheel connected by shaft to a centrifugal compressor. (Feel two pinwheels attached to a single spindle.) The compressor in turn boosts the pressure and density of the air delivered to the combustion chambers, drastically raising power output. A turbo is the ultimate power recycler.

Porsche adds a couple of turbo tricks. The Boxster S has small pivoting vanes that direct exhaust flow toward the turbine wheel in an optimum manner, diminishing lag at low rpm and easing restriction at higher rpm. To keep from stalling the compressor when the throttle is lifted, Porsche temporarily halts fuel delivery, leaving the throttle open, so enhance is offered when the driver gets back on the gas. Intake and exhaust valves both have variable timing and lift for enhanced efficiency auto stop/commence is now regular. Flow by way of the coolant and lubrication pumps varies according to demand. To give the new turbo fours an aggressive bark, there’s a valve in the optional Sport Exhaust that opens at 3500 rpm to bypass portion of the muffler. Push that button although idling, although, and the further sound is each a letdown and out of character, much more Subaru WRX than Porsche.

In addition to hiking each peak energy and torque (to 350 horsepower at 6500 rpm and 309 lb-ft at 1900 rpm), the S engine’s turbo fills in the 2500-to-4500-rpm valley in the preceding three.four-liter naturally aspirated engine’s torque curve. The new torque plot is dead flat from 1900 to 4500 rpm, mimicking an electric motor’s response when you dip into the throttle. That means you no longer have to drop a gear or wait for the tach needle to twirl to execute a swift pass.

This new torque bounty did prove frustrating at the track. Our acceleration-test capabilities were challenged by the Boxster S’s lack of launch handle, excellent traction, and 4500-rpm limit prior to clutch engagement. Coaxing more than a quick chirp from the rear wheels and maintaining the tach needle on the fruitful side of the dial was impossible. That is a long way of saying the new turbo-four engine is susceptible to bogging. We clocked the run to 60 mph in 4.three seconds, just a tenth of a second faster than the slightly lighter Boxster S we tested four years ago. The much better news is we beat that usually aspirated predecessor by .3 second and 2 mph in the quarter-mile, running 12.6 seconds at 113 mph. Leading-gear acceleration was slightly slower from 30 to 50 mph but a satisfying .7 second faster from 50 to 70 mph.

Addictive Character

Of course life is much more than stats. Tickle the throttle with 2000 or a lot more rpm on the tach and the boost gauge comes to life even though your decrease back receives a satisfying shove. This is not to say you will annihilate Corvettes from stoplights, but, like every single Boxster for the past two decades, there are compensating virtues. One is impeccable braking with superb pedal feel, work, and modulation. We measured a 144-foot, 70-to-zero-mph stopping distance, 3 feet shorter than the prior Boxster S and 5 feet greater than a Jaguar F-type S.

Cornering addicts who settle into the Boxster S’s cockpit must program on being regularly late for dinner. To improve response, Porsche bolted in the 911 Turbo’s rack-and-pinion steering gear, quickening the on-center ratio by 10 percent. Hints of actual road feel operate their way to the wheel, a rarity for electrically assisted steering. There’s just sufficient understeer at the 1.04-g cornering limit to let you know you’re not tethered to the road with steel cables. Pitch and roll motions are verboten thanks to shrewd suspension calibrations and adaptive dampers (which cost $ 2070 additional). For day-to-day haring about combined with supreme track-day competence, few sports vehicles at any value leading a Boxster S. Add to that a ride that by no means beats you up.

As convertibles go, this is a single of the best. The prime disappears and reappears in ten seconds at speeds up to 43 mph at the flick of a switch and serves as its personal boot when folded. There’s so small cockpit turbulence you can bask in the sun at 100 mph. Some of us enjoy the cupholders that swing out of a cleverly covered dash slot other folks vote no on that execution. 1 missing comfort is a handy location to park your smartphone. However, there are decent storage locations in the glovebox, center console, and door pockets, plus a reasonable quantity of luggage space divided amongst the trunks at each finish of the automobile. If only Porsche had contrived some way to actually see the new turbo-four engine brief of lifting the auto on a hoist.

The odd factor about this third-generation Boxster S is that dropping two cylinders saved no weight and the presumed purpose of larger EPA ratings also wasn’t realized. The auto tested right here is 52 pounds heavier than the aforementioned 2013 model, largely the outcome of adding bigger brakes and far more sophisticated dampers. EPA city ratings are unchanged at 20 mpg with the six-speed manual and 21 mpg with the PDK automatic, but there’s a two-mpg decline in highway mileage to 26 mpg for the stick and 28 for the PDK. We recorded 18 mpg overall—versus 19 for the prior Boxster S—and a commendable 30 mpg while cruising at 75 mph.

Big Spender

A wealth (literally) of possibilities in our test instance rocketed this Boxster S’s cost from $ 69,450 to a frightful $ 94,310. (For reference, the 911, with two a lot more cylinders and a second turbo, starts at $ 90,450.) The list of 18 choices integrated stuff that is virtually essential—the $ 2070 sport suspension, $ 1580 20-inch wheels, and a $ 1320 torque-vectoring differential—but there were costly upgrades that the frugal could live very happily without. Leather-trimmed heated and cooled 18-way memory seats, for instance, added $ 4725 to the tab.

The Sport Chrono package at very first glance appears like a quite high-priced ($ 1920) stopwatch perched atop the dash. Closer examination reveals this is the hard-core enthusiast’s bonus box. There are analog and digital displays controlled by a column stalk capable of logging hot laps, track position, and no matter whether you are gaining or losing speed. The a lot more valuable tool is a twist knob on the steering wheel borrowed straight from the 918 Spyder that lets you switch amongst 4 drive modes. This tunes the operation of a dozen or so systems to tailor the car’s dynamics to the driver’s mood. You can tighten up the variable powertrain mounts, lift the rear spoiler to its airfoil position, disable auto stop/start off, and activate exhaust overrun pops and snorts. Some of the noise is piped by means of a speaker, but the Sport and Sport Plus drive modes rid the soundtrack of any hint of a Volkswagen Beetle. That’s not to say it brings the return of the preceding flat-six soundtrack, which could outperform the lead tenor at the Metropolitan Opera. The new notes fall much more beneath the heading of karaoke howling, and the sound is sufficient of a loss to the all round encounter that it would send us to the utilised-vehicle listings in search of a prior-generation Boxster with the singing six alternatively.

Still, aside from the sound, consider the 718 Boxster S the antidote to autonomous driving. Steering that speaks with the road, a shifter that connects driver and driveline, and the raucous throb of gasoline and air converted to forward momentum may quickly be obsolete if the soothsayers are to be believed. To that we say appreciate the magic although it lasts.
