The 2017 Porsche 911 RSR goes mid-engine, purists be damned

Porsche unveiled its World Endurance Championship and IMSA WeatherTech Championship competitor with the 2017 911 RSR. And this 911 is different from the rest, as the 4.0-liter flat-six engine powering this beast is in front of the rear axle, not behind it. That's right, this 24 Hours of Le Mans competitor ditches the iconic rear-engine layout. Porsche isn't talking specifics on how exactly things are arranged back there. The engine is new, now based on the 991 911's block instead of the previous Mezger motor that's been used for years. The transmission design is new as well – it would have to be to accommodate the new location relative to the engine. The racecar has been engineered to meet the LM-GTE class, where it will go up against other mid-engine cars like the Ford GT and Ferrari 488 GTE. Moving the engine to the middle has given Porsche the ability to fit the 911 RSR with massive bits of aero, like the humongous rear diffuser that looks like it would be more at home on a machine of war. The only thing that can compete with the diffuser for size is the top-mounted rear wing, which shares a similar design to the one found on the 919 Hybrid. Going back to the engine, the direct-injected boxer motor, depending on the size of the restrictor, generates as much as 510 horsepower and sends all of its fury to the rear wheels. The engine is paired to a six-speed sequential gearbox, which drivers can employ through paddles on the steering wheel. The new engine doesn't have a lot of weight to push around as the 911 RSR, as required by regulations, weighs 2,740 pounds. Speaking of weight, the engine layout isn't the only change for the 911 RSR. For 2017, the car ditches its steel body for one that's made out of carbon fiber. The body attaches to the chassis via quick-release fasteners, making the vehicle easier to service as exterior elements can be removed with minimal effort. The racecar also gets a radar-based collision system – aptly named the "Collision Avoid System" – which is meant to limit the 911 RSR's encounters with faster LMP prototypes. Only time will tell if the new layout and aerodynamic components help the 911 RSR beat its competition. But there will be plenty of opportunities to see the racecar in action as Porsche plans to run the 911 RSR in 19 races during the 2017 season, the first of which will take place at the IMSA opener on January 28th at Daytona, where the racecar will make its track day debut.

2020 Chevy Corvette Stingray vs the world: How it compares on paper

The 2020 Chevy Corvette Stingray in its base form offers an astonishing amount of performance for the money. In fact, so impressive is the car's spec sheet that the Corvette kind of exists in two different competitive sets: one of cars priced similarly, and another with cars of similar performance and reputation. To get a feel for how it handles each of these segments, we've compiled specifications for those two sets of players. You can find the first set below, which looks at cars of roughly the same price point. Following that is a bit of analysis, and then there's a chart of cars with similar performance and reputation. And that chart will also have some analysis. Though final pricing for the Corvette hasn't been announced yet, we know the Corvette will start at less than $60,000. And as far as pricing goes, its closest competitor is the Porsche 718 Cayman, which also starts at just under $60,000. Both are mid-engined and rear-drive, but the Corvette offers an extra 195 horsepower and 190 pound-feet of torque. The Cayman does boast a curb weight of right around 3,000 pounds, so it weighs a few hundred pounds less than the Corvette, but it's likely not enough to make up for the power deficit. The Corvette's sub-3.0-second 0-60 time bears this out against the Cayman's best 4.5-second run. Impressively, though, the Cayman has more cargo space than the Corvette in a package that's nearly 10 inches shorter. The Cayman also still offers a manual option for those that prefer self-shifting. The 2020 Toyota Supra is on the cheap end of this sports car class, just crossing $50,000. It also boasts more power than the Cayman, though it's still down by 160 ponies and 105 pound-feet of torque to the C8. It's also about as roomy as the Corvette, despite being about the same size as the Cayman. Cargo space is a bit tighter. Its driving characteristics will likely differ, too as the Supra sits on a front-engine platform. It might even feel closer to a C7 Corvette in some ways. The other mid-engine entry in this price range is the 2019 Alfa Romeo 4C Spider. Its small 1.7-liter turbo inline-4 only makes 237 horsepower and 258 pound-feet of torque, but it's also far and away the lightest of this group at 2,487 pounds. That's roughly 1,000 pounds lighter than the Corvette. It isn't as fast as the Corvette in a straight line, but that lightness surely pays dividends in cornering and braking.

Porsche inspecting 2,500 Euro-spec Macans for damaged brake boosters

Porsche is investigating a potential brake issue with 2,500 of its new Macan CUVs. The inspection focuses on the state of the brake systems following tests that discovered the brake boosters may have been damaged during assembly.
Porsche has pointed out that, despite the concern, the affected Macans still meet safety regulations. The issue is predominantly found in European-spec Macans, which according to Porsche, have been delivered to consumers. Owners of affected vehicles in Europe will be notified and asked to come in for a brief, no-cost inspection.
American consumers, though, have no reason to worry. We reached out to Porsche Cars North America, who confirmed that the vehicles in question were assembled before US-spec cars were screwed together.
