Porsche 918 Spyder








This is the fastest and most powerful road-going Porsche model yet—the ultra complex and breathtakingly expensive 918 Spyder.
Carrying on a celebrated line of racetrack-inspired limited-production specials, the 918 Spyder was first revealed as a concept at the 2010 Geneva motor show prior to receiving an official production greenlight later that year.
Since then the targa-roofed Porsche has undergone an intensive three-year development program culminating in a final validation test at the Nürburgring in early September. There factory driver Marc Lieb established an official 6-minute, 57-second lap time, undercutting the Carrera GT by a stout 33 seconds. Up to now the GT was the fastest road-going Porsche model to ever lap the iconic German race circuit.
Power for the new carbon-fiber Porsche is a mid-mounted 4.6-liter V8 gasoline engine based on the engine from the earlier RS Spyder race car. Two synchronous electric motors -- one mounted up front and another at the rear -- supplement the V8. Together, the three power sources produce 875 hp at 8,500 rpm and a thumping 944 lb-ft of torque. (Some perspective: The Carrera GT's 5.7-liter V10 gasoline engine, designed for a Le Mans challenger, kicks out 603 hp and less than half the 918 Spyder's torque, at 434 lb-ft.)
Power is delivered via both a fixed gear and seven-speed dual-clutch gearbox; the former operates on the front axle to provide electric drive to the front wheels at speeds up to 165 mph, while the latter sits at the rear and drives the rear wheels with a combination of electric and gasoline-engine power. Depending on the drive mode selected, the new Porsche can operate in front-, rear- or four-wheel drive modes.
A 6.8 kWh lithium-ion battery mounted underneath the gasoline engine in back provides the energy used to run the electric motors. The battery comes with a seven-year guarantee and adds a significant 692 lbs to the 918 Spyder's 3,691-lb overall curb weight.
Nevertheless the official performance claims are spectacular. When fitted with an optional Weissach performance package (lightweight components paring some 88 lbs from the curb weight), the Spyder hits 62 mph in 2.6 seconds, 124 mph in 7.2 seconds and 186 mph in 19.9 seconds.
With a sophisticated aerodynamic package including a rear wing extending from the rear body work nearly 5 inches and providing three different downforce levels, the Spyder reaches a 214-mph top speed. In electric mode it hits 93 mph before the gasoline engine fires.
The truly remarkable thing about the new Porsche is while it delivers sledgehammer performance, its state-of-the-art gasoline-electric hybrid driveline allows it to record outstanding economy figures when driven at a leisurely pace. Porsche is quick to highlight the official 78.4 mpg consumption. However, it is achieved almost entirely in electric mode using a loophole in the European test procedure. In real-world conditions, you should expect figures similar to those of more conventional combustion-engine powered sports cars.

Mercedes SLS AMG Black Series 2014








                                                  
The current Mercedes SLS lineup is quickly filling up with a Coupe , aRoadster , a GT3 version , and, sometime in the near future, an E-Cell version. However, Mercedes isn’t done yet. As promised yesterday the fifth model in the line-up has been officially announced today: the SLS AMG Black Series.
The new SLS Black Series has borrowed some of the styling cues seen first on the GT3 version and of course combines them with some of the usual Black Series design elements. But first Mercedes worked on reducing the car’s total weight: they added lots of carbon fiber elements, a new titanium-made exhaust system, new wheels and some lightweight sports seats. As a result the new Black Series is about 154 pounds lighter than the current model.
When you add an improved engine under the hood: a 622-horsepowerV-8 engine, you will easily notice that the car’s performance numbers have also improved: the 0-to-60 mph sprint time drops 0.2 seconds and top speed is now 195 mph.

Underground Racing Twin Turbo Ferrari 458 Italia








The Ferrari 458 Italia is regarded by many as near-perfect (including us). Breathtaking styling, impeccable handling  and dynamics, and an engine unmatched in its naturally aspirated performance by any other automaker; it really is a gift sent from god.

In stock form the car’s 4.5-liter V-8 produces 570 horsepower and 400 pound-feet of torque, enough to blast it from 0-62 mph in less than 3.4 seconds and on to a top speed of 202 mph. Insane numbers by anyone’s standards, unless of course you happen to drive twin-turbocharged supercars every day.

So, understandably, for the guys at Underground Racing, a stock Ferrari 458 Italia just won’t cut it.

From the makers of the fire-breathing Lamborghini Murcielago LP670-4 SV and aLamborghini Gallardo capable of 250 mph top speeds, comes a new twin-turbocharging kit for the Ferrari 458 Italia. The kit is still in development but these pictures, which show a prototype version, reveal a very neat looking, almost OEM-like, twin-turbocharging kit for the Italian thoroughbred.  

Underground Racing’s new kit will come in two flavors; Stage 1, which is based on a stock 458 Italia engine, and Stage 2, which gets one with a rebuilt engine using custom internals.

As mentioned, the kit is still in development so no performance figures have been divulged as yet. However, if Underground Racing’s previous work is any indication, you can expect it to be one heck of a power-up.

koenigsegg one-1















koenigsegg is celebrating its 20th birthday this year, and for the occasion, the Swedish specialists are taking the hypercar to the next level with its new Agera One:1 at the 2014 Geneva Motor Show. In fact, it claims that, because it is the first production car with a one megawatt of power (1,341 hp), and a power-to-weight ratio of one-to-one (kilogram to horsepower), it goes beyond super or hyper and is actually the "world's first megacar."This road-bound rocketship is powered by twin-turbocharged, 5.0-liter V8 with the previously mentioned 1,341 hp and 1,011 pound-feet of torque. A seven-speed dual-clutch gearbox and electronically-controled differential makes sure all that grunt gets to the wheels. It is equipped with seemingly science-fiction features like variable geometry turbos in custom, 3D-printed housings and a 3D-printed titanium exhaust. While Koenigsegg claims top speed was not a factor when creating the One:1, it says that it has a simulated top speed of around 440 km/h(273 miles per hour), which would make it the world's fastest production vehicle. However, the One:1 can never hold the Guinness world record for top speed because only six will be built, all of which it says are already spoken for.Instead of speed, Koenigsegg says that the One:1 is meant to be a "track focused car." The Swedes claim 2 Gs of cornering capability on road-legal tires, thanks to up to 1,345 pounds of downforce at 160 mph from an active rear wing and independent, active left and right front flaps. In addition to those aids, the ride height, dampers and spring rates all adjust with the car's speed. The chassis can predict the road ahead using GPS, and drivers can even study telemetry later with a 3G connection sending the car's data to an iPhone app.The One:1 seems to be the next automotive quantum leap on par with the Bugatti Veyron. However, no one outside of Koenigsegg has actually driven it yet. It will be very interesting to see if real life stands up to what the megacar claims on paper. Scroll down to read the press release about the brand's spectacular 20th birthday present, and make sure to check out the high-res gallery, which includes a full spec sheet and great detail on the One:1's aerodynamics package.

Ferrari Laferrari








LaFerrari’s heart beat is  a 6.3-liter V12 engine with 789 horsepower married to a 160-hp electric motor. The combination is good for a full 949 hp and 663 pound-feet of torque, and Ferrari says the LaFerrari can punch to 62 miles per hour in under three seconds. Keep your foot planted and 124 mph will click by in a scant seven seconds, while top speed sits at a lofty 205 mph.
Engineers turned to a total of four different types of hand-laminatated carbon fiber to create a chassis that's both stiffer and lighter than would have otherwise been possible. With a 41/59 weight distribution, carbon-ceramic brakes and ultra-light calipers, the LaFerrari is unlike anything we've seen from the company to date. The automaker says its creation is the fastest in its long history

McLaren 650S










McLaren has disclosed pricing and performance specs concerning its new mid-range 650S model.
Packing a 650 HP (478 kW) punch from a V8 3.8-liter twin-turbo engine, the McLaren 650S coupe needs just three seconds to do 0-62 mph (0-100 km/h) and will cover the 0-124 mph (0-200 km/h) journey in 8.4 seconds. Hitting 186 mph (300 km/h) from a standstill takes 25.4 seconds en route to a top speed of 207 mph (333 km/h).
McLaren mentions the 650S is one second quicker than the legendary F1 when it comes down to the 0-124 mph run while in the standing mile is 0.6 seconds quicker as it can do it in 10.5 seconds at 139 mph (224 km/h). Interestingly, the British marque refers to the 650S as being "faster than rival stripped out road racers" while at the same time offering "far superior comfort, refinement and equipment."
These numbers are attainable if you are willing to pay at least 195,250 GBP for the coupe. Spider's performance figures have not been released but we do know the model costs 215,250 GBP. McLaren says the 650S coupe can return 20.1 mpg US (24.2 mpg UK or 11.7 liters / 100 km) with corresponding CO2 emissions of 275 g/km.
Sales of the McLaren 650S are scheduled to commence later this year, following the car's public debut next week in Geneva.

Lamborghini Aventador Twin Turbo LP700-4 By:Underground Racing





Underground Racing unveils the FIRST Twin Turbo Lamborghi Aventador LP700-4. With an Underground Racing Twin Turbo system, this 2012 Aventador is pushing out over 1200HP and reaches 60mph (0-100km/h) from 0 in an astounding 2.2 seconds. Check out our website for Races and Events where this amazing work of art will be displayed.

Twin Turbo Systems for the Lamborghini are now available.
Check out www.UndergroundRacing.com

Underground Racing is proud to release the first Twin Turbo Lamborghini Aventador LP700-4. Our team was very eager to get started with an Aventador project since it was first released from Lamborghini. Once this Aventador made it to Underground, we quickly began to engineer the TT system and full build for this amazing platform. Countless hours of R&D and hard work went into this project. We spent a lot of time driving and studying the inner workings of the Aventador, and this platform is amazing, but it still seemed to be missing something- acceleration. The kind you can only get from a friend I call, BOOST!

No doubt the Aventador is much more advanced than the Murcielago and even the LP Gallardo. It seems that the factory really tried to make it hard for the aftermarket world to modify the Aventadors though. However, the Underground Racing team moved quickly through the road blocks that exist. For now, the UR TT Aventadors will only be released with FULL engine builds. Through our research, we have found certain conditions that make this a requirement.

Now that the project is complete, I have to say this is truly one amazing car with the addition of the UR twin turbo build. We clocked the TT Aventador 0-60 mph time in 2.2 seconds on OEM street tires, normal air pressure and on a regular road. This Aventador drives just as it did in stock form, just a lot faster. The Aventador shifting is amazingly fast and we were also able to pick up a bit faster shift time with our Quickshift upgrade.

The Underground Racing TT LP700 system is a true work of art. Unfortunately, due to several attempts by other tuners to build knock off versions of our systems, only limited portions of information and images of the turbo system will be shown. As always, doing what only Underground Racing does with a Twin Turbo Lamborghini, we plan to see how far we can push the limits of the TT Aventador at several types of events with our demonstration TT Aventador. Stay tuned for more videos of this beast
