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.

Porsche 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype. Scope out the latest episode in the video below.

Best compact SUVs of 2022

Compact SUVs are now the go-to choice for family transportation. Actually, considering how popular they are, they have clearly moved beyond only family duty. With such popularity, though, comes an awful lot of competitors, and it can be difficult to figure out which one might be the best compact SUV for you.  It's important to note that by "compact SUV" we're talking about a specific segment. As we describe in our more comprehensive "Best small SUVs" list, there are also subcompact SUVs that vary widely in size amongst themselves, but are clearly smaller than the SUVs below. Frankly, today's segment of compact SUVs isn't exactly compact — some have more cargo space than vehicles that are considered midsize based on their exterior dimensions. They've all grown considerably over the years. While many lists out there just rattle off every vehicle available in a segment, we thought we'd be a bit more helpful and curate your shopping a bit with the top-recommended choices reviewed by Autoblog. We've included both mainstream and compact luxury SUV choices. Best compact SUVs of 2023 and 2024 2024 Honda CR-V Why it stands out: Best-in-class space; excellent hybrid powertrain; sharp interior style; Honda dependabilityCould be better: No lower-price base trim levels; no sporty or off-road niche models; no plug-in hybrid Read our full 2024 Honda CR-V Review Consider the CR-V the baseline for any compact SUV search, and look extra closely at the superb CR-V Hybrid option. Objectively speaking, it's tough to beat due to its massive cargo capacity, voluminous back seat, strong-yet-efficient engines, well-balanced driving dynamics, competitive pricing and features,  and well-regarded reliability. It's easy to see why it continues to be such a best-seller: for the vast majority of compact SUV buyers, and especially families, it checks every box. That's been the case for many years now, however. The all-new 2023 Honda CR-V changes things up by adding a bit more style and character, particularly in terms of its interior design and how surprisingly enjoyable the Sport and Sport Touring hybrid trim levels are to drive.
