Click above for a high-res gallery of the Caterham RST-V8 Levante.

Caterhams have always been the model for minimalist motoring and it's rare that owners have been wanting for more motivation, but RS Performance has answered the call of a few owners that want insane power to match the Caterham's spartan looks.

Packing a supercharged 2.4-liter, V8 driving the rear wheels through a six-speed gearbox, RS Performance is giving well-heeled drivers 550 hp (at 10,000 rpm!) to simultaneously dry their hair and wet their pants. With a curb weight of almost 1,150 pounds, that means a power to weight ratio of around 1000 hp per ton and a 0-60 time of under three seconds.

Getting that grunt to the ground is difficult, at best. With the majority of the body panels being replaced with carbon fiber bits, along with an F1-style front splitter, steering wheel and Kevlar seats, the lack of mass is something drivers will have to overcome. Thankfully, the chassis, sticky rubber and traction/launch control should keep things in check.

If the £115,000 cost of entry for the supercharged version is a bit more than your wallet can bear, a naturally aspirated variant is available as well producing a "paltry" 380 hp. Included in the cost of the RST-V8 is a two-day driver training course when you take delivery. Good call Caterham.

The full press release with all the technical details is posted after the jump.

When we last saw the Lotus Esprit in 2004, it was equipped with a 3.5-liter twin-turbo V8 rated at about 350 hp. Offering much more motivation than its early turbocharged 4-cylinder powerplant, the Esprit V8 was quick -- pedal to the floor, the two-seat coupe could punch through 60 mph in less than 5 seconds. Impressive as it was just a few years ago, there are more than a handful of cars (at half the price) that can shame the Lotus back across the Pond today.

To keep the upcoming 2011 Lotus Esprit at the front of the pack, it is rumored to be fitted with the 4.4-liter twin-turbo V8 found under the hood of the recently released BMW X6. The powerplant is rated at 400 horsepower with only light boost under the German's hood. Under the fiberglass cover of the future British Esprit, it will most likely be tuned to deliver nearly 500 horsepower. It will need every bit of power it can get, as the new Lotus will be competing with the Porsche 911 Turbo, Ferrari F430, and the new Nissan GT-R.

We've heard this tune before. Automakers have pushed vehicles to the zenith of attainable on-road performance, with even family vehicles being outfitted with fire-breathing engines. Anything you buy today will run rings around the performance cars of yore. Boomers may get misty-eyed about how great the glory days of the 1960s were for hot cars, but that's just the filthy exhaust clouding their judgement. The golden age of performance is now. Just as it went down nigh on 38 years ago, big V8 thumpers are having their death knell sounded. Scott Burgess posits in the Detroit News that the muscle car formula could undergo some revision.

Burgess spoke with GM's Troy Clarke, who thinks that muscle cars will evolve into vehicles that sell more on the strength of their style and innovation, rather than live axles and cubic inches. We agree that there will be widespread evolution and experimentation when it comes to powertrains, but we thought muscle cars already sold largely on their stylishness. We went digging at Ford to take a look at Mustang sales to see if our suspicions could be confirmed.

It could be CAFE, it could be gas prices, it could be the everpresent chatter on all things green, it could be that it's just so bloody hot on Earth nowadays, it could be all those folks in California begging for clean air. But according to recent data and a study by Edmunds.com, V8's simply aren't in vogue anymore, with overall uptake among new car buyers dropping four percent over the last two years.

Along with the decline in SUV purchases, those who are still buying SUV's are shunning V8's twice as quickly, with a nine-percent decline over the last two years. Among full-size sedan and coupe buyers, seven-percent fewer checked the "Big V8" box on the options checklist.

The only place V8's aren't sliding down the mountain is in the full-size pickup market, where four-percent more buyers are still going for stump-pulling power. The theory is that "casual" pickup buyers are opting for something less thirsty, leaving more of those folks who actually haul things to buy pickup trucks powered as God intended. But with even full-size pickups feeling the sales pinch, it looks like the march toward 35-MPG has begun.

Land Rovers have run Jaguar's rorty AJ V8 engine since Ford got tired of sourcing engines from BMW. CAR magazine has dug up information on some mules running around in Finland with a new 4997cc engine underhood. Their photographers also caught the vehicles while they hung out in a parking lot full of tantalizing 2 and 7 series Volvos. While the AJ is a great motor, it's well into its design life. Range Rover's new engine is being developed with Bosch, and sports direct fuel injection to boost efficiency while keeping power up and emissions down. Output is rumored at 350 horsepower in naturally aspirated form and 460 ponies come to the party when a supercharger pressurizes the intake. The new engine will wind up in the engine compartment of Land Rovers, Range Rovers, and Jaguars, and will be part of a freshening of Landies and Rangies expected to drop soon.

click above for more high-res iamges of the V8-powered Scion xB

Forget about body kits, custom fiberglass enclosures for your woofer and LCDs in the headrests. This is the only way to make the Scion xB entertaining in our humble opinion. Oh yeah, Scion wants you to think its cars are more fun than a box of rocks, but like Flava Flav said, don't believe the hype. We'll even forgive the fact that there's a big, dumb carburetor sitting atop the Chevy-based small block. This first-generation xB is owned by a guy named Rick, who apparently knows his way around plasma cutters, nibblers and welders. It's not quite finished yet, as evidenced by the photos showing a stripped interior and lots of zip ties, but Rick's Scion is already quite the sleeper.

Peering inside the engine bay, it's the tidy dimensions of the small block FTW. A transmission hump/center tunnel had to be added, and the chassis was converted to rear-wheel drive, too. Keep in mind, this is the smaller, original xB. The overinflated second-generation would have even more space in the engine room for this sort of chicanery. There's obviously some time and money spent to give this ho-hum little box a big infusion of epic cool, and we bet that's all worth it when you can take in the looks of discongruity as you blow the doors off the unsuspecting.

BMW's twin-turbo 3.0L inline-six has been a rousing success, with nothing less than a Wards 10 Best Engines award sitting in its trophy case. The praise is understandable and well-deserved, as the engine uses a combination of forced induction and direct injection to serve up a torque curve that's far beefier and flatter than what should be expected from a engine of its size. So what next for the propeller brand? Simple -- take similar technology, add it to the company's 4.4L V8 and toss in a dash of unconventional packaging to make everything fit.

BMW put its latest jewel on display at the 2008 Detroit Auto Show, and we snapped some shots of it to give you an idea of why this engine is so special. We've included those photos in one of our galleries, and below the fold, we've thrown in a few observations.

Monster motors were the order of the day in the late 1960s, and GM's 427 was a part of that class. The drawback to a big-block's burly output was, and still is, the increased weight of the engine. While big blocks are a hoot for straight line shenanigans, a small block car is often a better all-around performer. That goes out the window for most of us upon tapping that vast well of torque, and there was a solution direct from GM. The ZL1 was a 427 rendered in aluminum to save weight and carried a 430 horsepower rating. The ZL1 is the stuff of legend, commanding the sharp intake of breath when mentioned with the Corvette, and reverent silence should the COPO Camaro be cited.

GM Performance Parts is whipping up a limited run of all new ZL1s, built from the same tooling as the original. A total of 427 of the Anniversary 427 Big Block engines will be produced, creating a new piece of automotive unobtanium while leaving the ZL1 mystique intact. You might even argue that the new engine run will add to the lore. We'll get to see just how much of a clamor there might be for these new engines when the very first Anniversary 427 Big Block crate engine, serial number 001, goes up for bid at the upcoming Barrett-Jackson auction. The remaining 426 engines will be available soon from GM Performance Parts dealers, and will likely be snapped up like rabid moms going after Hannah Montana tickets.

Yea, we know - the automotive press has featured a whole bunch of Corvette ZR1 content lately (including us!), and readers are probably getting a bit tired. However, we figure that a cutaway of the mighty supercharged LS9 should be interesting enough to justify yet another post on the revived King of the Hill.

Painted in monochrome silver as GM is wont to do, this particular display isn't particularly photogenic. Still, we were able to capture some details that aren't easily observed in 2D drawing or press releases, so click through the jump for a variety of shots.

It's been a regular smorgasbord for fans of Mercedes roadsters over here, with this teaser shot of the upcoming facelifted flagship SL hitting the web just a few days after Benz revealed the updated version of the smaller SLK. But while the SLK was revealed first in "ordinary" guise, the image above shows the full-fat, fire-breathing SL 65 AMG version.

We already know that the facelift will feature a heavily revised front end with new headlight treatment, but from the rear three-quarter view Mercedes is enticing us with, all can also see the revised taillights, new diffuser with quad exhausts, and a subtle lip spoiler. The new SL 65 also appears to be riding on AMG's latest 19-inch five-spoke rims, similar in style to those found on Stuttgart's other earth-pounding range-topper, the Porsche 911 Turbo.

With the teaser shot also comes information on the two AMG models in the new SL range: the SL 65 AMG we see here, and the SL 63 AMG. The former packs AMG's twin-turbo V12 pumping out a whopping 612 horsepower, while the latter is driven by Affalterbach's 6.3-liter V8 with 525 horsepower, replacing the outgoing 55 version and in the process distancing it from the smaller SLK 55 AMG revealed previously.

We'll have to wait to see more images of the new AMG roadsters, including those that celebrities will be wrapping around trees.
