2013 Porsche Boxster

The newest generation of the Boxster, chassis code 981, benefits from many of the same technological advancements found in the 991. The base flat-six has shed 200cc of displacement going from 2.9-liters to 2.7-liters. Everyone of those lost cc's came from a shortening of stroke, going from 77.5mm down to 72.5mm, roughly 0.2-inches, allowing the smaller engine to rev higher in search of more power.

This helps the smaller base engine pick up an additional 10-horsepower, 265-horsepower total, along with help from an upgraded Siemens engine management system and the direct fuel injection system from its bigger brother. The smarter computer coupled with the cylinder cooling effect and more efficient mixture stratification of the direct injection has allowed Porsche to bump the compression ratio from 11.5:1 to a race car worthy 12.5:1. More squeeze and better injection still couldn't make up for the smaller displacement in torque. The new engine loses 7-lb-ft although it can produce peak torque for an extra 500 rpm, with 207-lb-ft being available from 4400-6500 rpm.

The Boxster S stays at 3.4-liters but receives an upgrade from Siemens SDI 3.1 to SDI 9.1 engine management. The power peak moves from 6400 rpm up to 6700 rpm and the extra revolutions bump power from 310 to 315 hp. Peak torque is also available for another 300 rpm spreading from 4500-5800 rpm. Both 2.7-liter and 3.4-liter flat-6 engines use the new tech to clean up their act significantly. In the European Urban Cycle, the standard Boxster PDK has improved its rating from 17.3 mpg to 22.2 mpg, while the Boxster S PDK has gone from 16.7 mpg to 21 mpg. Manual models see similar improvements and obviously CO2 emissions fall accordingly. Since European testing is performed differently than in the US, these numbers aren't directly transferable to anything the EPA will list, but the improvements will be similar.

Like the 991-generation 911, the new Boxster will grow in wheelbase and overall length. While the wheels spread out by 2.4-inches, the overall length only grows by 1.3-inches. Overall width of the car stays the same while the track width grows by 1.6-inches in front but just 0.3-inches in the rear. The base Boxster now comes standard with 18-inch wheels and the S moves up to 19-inch. The outside diameter of the tire has grown roughly an inch. The taller tire means the overall gearing for the cars is 4.1 percent taller in the manual and 4.3 percent taller for the PDK equipped cars.

Technical specifications aside, the driving experience will change in similar ways to the 991 as well. Porsche has changed the Boxster over to the somewhat controversial electric power steering as it did with the 991. While it doesn't have the same tendency to follow every road irregularity and transmit every nuance of terra firma, it will still fill the drivers' hands with as much feedback as their brains can process. The 991 doesn't feel like a classic 911, but the Boxster never seemed to deliver quite the same experience anyway. The Boxster's steering ratio has been tightened up, from 17.1:1 to 16.5:1 in the center of the rack with a corresponding change of 13.86:1 down to 12.4:1 in the variable section. Faster steering and wider front track combined with Porsche dropping 60 lbs off the curb weight should give the roadster even more sprightly performance. The last time we tested a Boxster S, a 2009 manual transmission model to be exact, it did 0-60 mph in 4.5 seconds. Porsche rates the same car at 5.3 seconds, while it rates the 981 Boxster S manual at 5.1 seconds. It rates the PDK S as 0.2 second faster than the previous model as well at 5.0 seconds flat. With slightly less torque, the standard 981 Boxster is only 0.1 second faster with Porsche rating the manual car at 5.8 seconds and the PDK at 5.7 seconds. When the first test rolls around, we won't be surprised if a PDK equipped Boxster S doesn't come in just a tick under the 4 second mark. -Michael Febbo

Turbo Flat-Four Option Coming to America, Says Porsche's R&D Head
"For us, the Boxster really is the entrance into the sports car range for Porsche," said Dr. Wolfgang Hatz, head of Porsche R&D. "In the U.S. it starts at under $50,000 [without destination]. It is a competitive offer for a Porsche -- to enter the Porsche family. Yet I'm surprised how people don't know that we are so competitively priced in the segment," he continued. "My neighbor, for example, always drove a BMW Z4. I said, 'Why do you drive a Z4?' So I got him to change to a Boxster. Then, after one year, you know what he did? He bought a 911 Cab!" So, Dr. Hatz, you're saying that the Boxster is a vehicular gateway drug? A means to get drivers into bigger, faster Porsches? "Yes!" exclaimed Dr. Hatz. "And it's a real Porsche -- ja."

The 2013 Porsche Boxster is quite a potent drug as well. Power is up in the base model, despite a new, smaller displacement 2.7-liter flat-six that produces 265 hp. That's a 10-hp increase over the outgoing 2.9-liter mill. The Boxster S retains its 3.4-liter flat-six, but gains 5 more horsepower to 315. "But to be honest, we are also working on a forced induction flat-four," said Hatz. This long-rumored engine, reportedly a 2.5-liter with as much as 360 horsepower (talk of a 1.9-liter variant has also been rampant), is a response to increasingly stringent global fuel economy standards, and is "absolutely" coming to America, says Hatz, though he would not confirm any output figures or whether the turbo four-cylinder would receive the new Boxster's heavily revised six-speed manual and seven-speed PDK dual clutch transmissions.

About those transmissions: While they are not all-new, they are "complete evolutions," says Hatz, with "much quicker, more emotional shifts." Speaking of emotions, the Boxster has all-new sheetmetal with a more masculine edge. Although the wheelbase remains the same, the Boxster's all-new 991-derived chassis is a bit wider and sits on a larger diameter wheel and tire combo. "I think the Boxster is really becoming more adult. It's a little bit wider, a little bit lower, and it's lighter," said Hatz.

How much lighter? Porsche hasn't provided the exact curb weight, but Hatz claimed it could be up to 100 pounds lighter than the current model (2943 pounds in base trim and 2978 pounds for the Boxster S), thanks to a weight-savings program that increased the percentage of aluminum and high-tensile steel in the chassis. "It is unbelievably stiff! You won't don't feel that this is a roadster; you'll think it's a coupe," said Dr. Hatz.

To take advantage of this stiffness, Hatz's team added new features like dynamic engine mounts, which first appeared on the 911 GT3, and the Porsche Torque Vectoring system, which distributes torque between the rear wheels via a mechanical limited slip differential.

Pricing has been set at $50,450 for the base model ($1400 more than a 2012 Boxster), which includes the $950 destination charge. The Boxster S is priced at $61,850 including destination ($2300 more than a 2012 model). Both cars go on sale later this year, and will be followed shortly by a new Cayman and Cayman S. We're very interested in when the turbocharged flat-four that Hatz confirmed will come to America, the biggest Boxster market. Hatz's bottom line for Porsche's latest dose of speed?

"We made a tremendous step with the 991 Cabriolet. It is much stiffer than the 997 Cab. But in the Boxster, you don't feel, under any circumstances, that this is an open car."
