The Windsor Castle Concours d'Elegance in pictures, courtesy of Bentley

Bentley went to the Windsor Castle Concours of Elegance as the main sponsor and showed off six of its best among the gathering of "60 of the finest motor cars in the world," including the 4¼-liter Bentley 'Embiricos' Special built for a Greek shipping magnate and gentleman racer in the 1930s.
Even better, for us at least, is that when Bentley decided to capture the moment it took pictures of most of the metal on the lawn, not just the Bentleys. Thanks to that, we have a high-res gallery that's home to rarities like the Vauxhall 30-98 Type OE Boattail Wensum Tourer, beauties like the Bugatti Type 57S Atalante, long-tail Ford GT40, Maserati Tipo 60 Birdcage, Aston Martin DB4GT Zagato, a sinister Ferrari 250 GTO and the even more sinister Rolls-Royce Phantom Aerodynamic Coupe, among others. All you need to do now is click and enjoy.

2014 Ferrari F12 Berlinetta

Most cardiologists and physiologists maintain that a human's maximum heart rate is calculated with a mathematical formula: subtract a person's age from 220. But some leading doctors are now questioning the established academics, which trace their origins back to 1970, claiming that a simple formula isn't accurate for people of all ages, in particular those who are older. Rather than endorse the time accepted calculation, this progressive group argues that maximum heart rate equals 208 minus 0.7 times age.
While medical science continues its debate, I recently discovered a more elementary approach that disregards age and physical condition, and it requires no math.
To reveal a human's true maximum heart rate, I propose strapping test subjects into the driver's seat of a Ferrari F12 Berlinetta and then firing up its ferocious V12.

LaFerrari testing with turbo V6 F1 engine?

If Ford went and tested a NASCAR engine in a production Ford Fusion, it'd just be silly. Ferrari testing its new 1.6-liter, turbocharged V6 Formula One engine in a LaFerrari hypercar is not silly - it's excellent.
Now, we can't be certain if the video shown above is actually Ferrari's new F1 powerplant. Based on the big roof-mounted intake, the weird sounds coming from the camo'd LaFerrari and the teasers we've been hearing from other F1 engine providers, the race engine is a tantalizing idea.
The other possibility, perpetuated by our friends over at Road & Track, is that Ferrari is using the LaFerrari to test a next-generation powerplant. That looks good on paper, but this car strikes as being far too loud for any road legal engine. What do you think? What's Ferrari up to at Fiorano?
