MONTEREY, CALIF.—Few car brands have managed to stake out the kind of mindshare occupied by Porsche. Celebrating its 75th anniversary this year, the company just held its seventh Rennsport Reunion, a car show crossed with a race meet at the Laguna Seca racetrack in Northern California. It drew a crowd of more than 90,000 Porschephiles at the end of September.

From its start in the aftermath of World War II, Porsche has concentrated on using clever engineering to make cars for people who like to drive. Much of that clever engineering was first proven at the racetrack before making the jump to something a bit more road-legal. And almost all of it was on display at Rennsport Reunion, from early engines with twin spark plugs and early experiments with aerodynamics through turbocharging, hybrids, and now extremely high-performance EVs.

The early days

The first Porsche-designed racing cars predate the family firm and date back to 1934 and the fearsome Auto Union V16 . But the first factory-built Porsche racing car took five years to follow the company's first road car , which appeared in 1948. When Porsche started building 356s, customers started racing them in sprints, hill climbs, and long-distance races, complete with pleas to the factory to see if it couldn't deliver a little more power, particularly from American owners.

MARINA DEL REY, Calif.—Porsche's plans to electrify 80 percent of its product range by 2030 requires the German automaker to offer more than just Taycans. Other than the 911, which probably won't be a battery-electric vehicle (unless and) until solid-state batteries alter the energy-to-mass calculations, that means everything else in the lineup will need to trade engine, exhaust, and fuel tank for a battery pack and an electric motor or two. And it's starting with its second-best-selling model, the Macan crossover.

An all-new Macan arrives in showrooms next year for model year 2024 and will confusingly coexist for some time alongside the current gas-burning Macan, which recently went through its midlife refresh. The new version is entirely electric, however, and will be built on a new 800 V architecture called Premium Platform Electric, being developed by Porsche together with its corporate sibling, Audi.

Spy shots of barely disguised Macan EVs have been circulating for some time as Porsche puts on its finishing touches. Some of those test cars have even been spotted here in the US; a couple of years ago, it decided to develop local market prototypes. For our market, that means things like making sure the satellite radio works and that the advanced driver assistance system (or ADAS) can read our road signs and knows that on US highways, faster traffic rarely sticks to the leftmost lane.

The introduction of Apple CarPlay in 2016 was a game-changer. Until then, connecting your phone to your car meant bothering with Bluetooth, and if you wanted to use a smartphone navigation app, you probably needed some kind of phone holder clipped to an air vent or suction-cupped to the dashboard. Being able to cast your phone's screen to the car's infotainment system turned out to be extremely popular, and by 2020, it was a feature that almost half of all new car buyers wanted .

This has not sat well with every automaker; in March of this year, General Motors made headlines —and generated a lot of comments—when it announced it was killing off support for casting interfaces (both CarPlay and Android Auto) from its future products. But where GM saw a threat, Porsche saw an opportunity. And now it has built a new iOS app, making use of an Automaker toolkit provided by Apple. This little-known feature is only offered to OEMs and allows them freedom beyond the restrictive user interface guidelines laid down by Apple.

Porsche's customer research found that the overwhelming majority of its customers have iPhones and prefer using them for things like navigation. "Obviously, you have to switch back and forth to control some features around media, for example, some more specific features around climate," explained Cyril Dorsaz, principal product manager at Porsche Digital. "And ultimately, we learned through customer research that this is something that our customers are not really happy with."

CARMEL-BY-THE-SEA, Calif.—Every few years, Porsche holds a big celebration of its racing heritage at the Laguna Seca racetrack in Monterey, California. Called Rennsport Reunion, it's a big deal, drawing a far bigger attendance than when racing series like IndyCar or IMSA visit. And attendees are a passionate crowd, prepared to wait in line for an hour or more just to visit the official merch store.

Rennsport Reunion 7 took place last week, and it was a special one, as this year is Porsche's 75th anniversary. Among the cars brought over from the company museum was the very first to ever bear the Porsche name, the prototype 356/1 roadster.

And Porsche let us drive this priceless artifact.

PORTLAND, Ore.—This year's Formula E season draws to a close this weekend, with the final two rounds taking place in London. The title fight is a three-way contest, with Avalanche Andretti's Jake Dennis leading Envision Racing's Nick Cassidy and Jaguar TCS Racing's Mitch Evans. Last month, the series held a race here in the US on the opposite coast of its traditional home in Brooklyn. Formula E did something outside its comfort zone, holding a race at permanent road course—Portland International Speedway. And as Ars found out, it was a good decision; this leafy race track with its volcano backdrop felt like a much better venue for Formula E than a humid parking lot next to the Hudson River.

It was also our first opportunity to see the series' new cars in action, and they're significantly lighter and more powerful than the Gen2 machines . As ever, the drivers have a lot of work to do to manage energy in the cars, thanks to restricted telemetry to their engineers in the pit lane and new tires that prioritize sustainability over outright grip.

This isn’t a city center street circuit

Portland was not the first Formula E race we've attended; we were on hand to see the series' rather chaotic Miami ePrix in 2015, and Ars logos even ran on a pair of cars at that year's London ePrix . Miami was not a repeat event for the sport, and the Long Beach ePrix in California was held only twice, in 2015 and 2016.

One hundred is something of an arbitrary number, an accident of how many fingers we happen to have. But in years, it represents a long time to keep doing something again and again: like the 24 Hours of Le Mans, an annual race around an 8-mile circuit in France that exists not just as a way to entertain but also to improve the cars we drive on the road. Windshield wipers, disc brakes, fuel injection, and laserbeam headlights are just a few examples that were proved in the cauldron of the 24 Hours before appearing on cars like the one you might drive.

This weekend saw the centenary edition of the race take place. Anticipation had been building for months thanks to a new ruleset that has revitalized the top class of prototypes , now called Hypercars. After several years of Toyota facing little competition by meagerly funded privateer teams, 2023's entry list also included cars from other major manufacturers—Cadillac, Ferrari, Peugeot, and Porsche.

Legends return

Each has raced at Le Mans before, the European makes with quite some success. Across 91 actual races—world wars prevented running some years—Porsche's entries notched 19 wins, more than anyone else. Audi has the next-best record, but it has opted to spend its racing budget on Formula 1 for the foreseeable future .
