After 3 years of cool enthusiasm, Jaguar has announced some big changes for the 2010 Jaguar XKR. Actually, they’re trying to tell us that LED taillights and a new steering wheel are big changes. But, early reports like this one at Jalopnik, verify that there really is only one big change—the engine. The old supercharged 4.2L, which produced a fur-ball gagging 420 hp has been swapped for blown 5-liter cranking out 510 hp of feline fury. Expect this to be another fast cat.

Between 1928 and 1932, Mercedes-Benz built what was the fastest car of the time—the Mercedes-Benz SSK. Designed by Ferdinand Porsche, the SSK was that legendary engineer’s last design for Benzo before he left to start his own little car company (you may have heard of it).

80 years later, Mercedes’ AMG division has announced the next generation SSK—and it’s planned to compete directly with the modern Porsche 911s, “in your face, Ferdinand!”  Spy photos have yet to leak; however Autocar, who broke the story, has a nice rendition here.

The K in SSK stands for Kurz, German for “short.” But, if you’re kurz on cash, sorry, this new Porsche/Audi eater is set to retail for around $130,000 USD. But that’s a lot cheaper than a 1929 SSK that sold for $7,400,000 USD back in 2004!

The LFA is one of the most anticipated super cars of 2010. It's Lexus's first foray into the high end market and they are aiming to make a serious splash. Over a decade of planning has gone into the development of the LFA, and Toyota has built nearly everything in-house. The end result is quite the marvel: the V10 pushes 552 horses and 354 ft-lbs of torque and it sports an astounding 0% steel it it's chemistry. Rather than using conventional metals, Toyota focused on using carbon fiber and aluminum, ending up with a 65/35% split between the space age materials. This helps give the LFA a 3,262 pound curb weight.Yamaha helped tune the exhaust, which resembles that of an F1. The suspension is firm and balanced, but not quite as point-and-shoot as a Lotus Elise.

This front-engined Lexus sprints to 60mph in 3.7 seconds and can accelerate all the way up to 202mph. Pretty quick, but not as zippy as GT-R, and miles behind a ZR1 Vette's top speed, both of which cost less than 1/3 of the LFA. So is the 9,500 RPM redline really worth the $375,000 price tag? Auto Blog has got a hands on review that is, as usual, extensive and thorough. Well worth the read, check it out at AutoBlog.com.

Porsche is an incredible car company.  Their 911 is one of the most iconic sports cars ever made, and they've been playing that same note for over 45 years and still remain successful. While true Porsche lovers will say that the 911 (and all it's iterations) are perfectly designed and should stay as they are, others might disagree, they might say Porsche needs a new face to match to strike fear in the eyes of the competition. Lets face it, the Panamera is fugly at best and the Cayenne looks like a 911 with a lift kit and an extended hatch.
