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.

Preserving automotive history costs big bucks

$1.8 million is spent each year to maintain GM's fleet of 600 production and concept cars.
When at least two of the Detroit Three were on the verge of death a few years back, one of the tough questions that was asked of Ford, General Motors and Chrysler execs - outside of why execs were still taking private planes to meetings - was why each company maintained huge archives of old production and concept vehicles. GM, for example, had an 1,100-vehicle collection when talk of a federal bailout began.

1950s car ads are timeless

Usually around the Super Bowl a few great car commercials show up, but for the most part auto ads today pale in comparison to the '1950s and '60s. In an era with a truly viable magazine industry, automakers would take out gorgeous full-page spreads to get the word out about their wares. It was also a time when imports were just hitting the US, and there was a boom in sports cars. Car and Driver has gone for a dig into its advertising archives from when the book was known as Sports Cars Illustrated for a truly great viewing experience. You can imagine a young Don Draper mulling over the copy for these ads, but some of it is laughably quaint today. For example, there's a great image of a driver whipping an Austin-Healey 100 around a track. The italicized red text proudly proclaims, "From 0 to 60 MPH in 10.5 seconds." One of the beautiful parts about these advertisements is that you seldom see photos of the cars. Instead, there are often detailed drawings that slightly distort the vehicles' lines. With this approach, the Porsche 356 ends up looking far more curvaceous than in real life. Plus, the front end of the Chrysler 300 looks large enough to land a helicopter on. The whole thing is worth scrolling through. There are some fascinating glimpses into auto history like an ad for Abarth exhausts before the brand was just known for tuning Fiats.
