Chevy Camaro ZL1, Lexus LFA celebrate National Donut Day

Happy National Donut Day, everyone! While some of us may have already celebrated this high-caloric holiday at our local Dunkin' Donuts or Tim Horton's, Chevrolet and Lexus have taken the opportunity to offer us delicious donuts of a different sort. Using a "professional donut maker" and a 2013 Camaro ZL1, Chevy has released a video of its 580-horsepower coupe laying down some serious rubber. Lexus has countered with its LFA supercar and, oddly, LPGA pro golfer Natalie Gulbis.
Just like many of the donut chains across the country, Chevy and Lexus are giving away these donuts for free. Not only do their donuts contain zero fat, they're also easily enjoyable over the Internet, albeit nowhere near as tasty as a Krispy Kreme. Scroll down to enjoy both videos.

Lexus RC F is a predatory sport coupe with a 450-horsepower beating heart

Take a look at that face. We can't be the only ones who see an automotive Predator staring back, right? Certainly, the Lexus RC F Coupe boasts a visually striking design that some are going to love and others are going to hate, but we can at least appreciate that it's aggressive, especially compared to the standard RC Coupe that we saw at the Tokyo Motor Show. And with good reason - there's a 5.0-liter V8 engine sitting under that massively domed hood with "more than 450 horsepower," along with a newly calibrated eight-speed automatic gearbox.
Interestingly, Lexus has tuned the RC F's engine to run on an Atkinson cycle under most circumstances, while it switches to the more typical Otto cycle when more power is required, presumably using some sort of advanced variable valve timing technology. Helping put that power to the ground with all those ponies wreaking havoc underhood is a torque vectoring differential, a first from Lexus.
Also involved in keeping the RC F planted is an aero package that includes wings and ducts galore. The headline bit is an active rear wing that deploys at 50 miles per hour and retracts back into the deck when the car drops back to 25 mph. A clear-coated carbon fiber roof can optionally join that carbon rear wing. There are apparently going to be three 19-inch wheel options, including the ones you see in our live image gallery above.

Lexus looking for performance with 600-hp LF-LC?

Lexus has been keeping development of the production version of its LF-LC concept tightly under wraps. Last we heard, that halo GT car had received the green light for production, but that was over a year ago. Since then, things have been pretty silent. Finally though, fresh rumors about the luxury coupe are starting to leak out, pointing toward the model's powertrain lineup.
According to unnamed sources speaking to Motor Trend, the production LF-LC will eventually sport three very intriguing engine options. The base model will reportedly use a naturally aspirated V8 providing around 450 horsepower - very similar specs to the upcoming RC F. The next step up will allegedly be the upcoming hybrid powertrain shared between BMW and Toyota pumping things up to around 500 hp. Finally, a top-of-the-heap F version will use a twin-turbocharged version of the RC F's 5.0-liter V8 to bring output to 600 hp. The insiders even claim that the hybrid and the twin-turbo V8 could find their way into other Lexus products like the LS and possibly even a more beastly RC.
None of this speculation sounds too outlandish. Lexus could get more capacity out of the RC F's tuned V8 by shoving it into other models, and rumors are flying about performance cars spawned from BMW and Toyota's partnership. Given Lexus' recent embrace of turbocharging, even the twin-turbo V8 doesn't seem too dubious. That said, with no hard facts to back up the rumormill, we'll have to keep waiting to see what the LF-LC shows up with.
