For the 2015 model year 370Z NISMO, Nissan have developed a number of styling and engineering upgrades. The changes start on the outside, where the car is treated to a new front bumper with a larger grille, additional air intakes and new LED driving lights. The lower sections of the front bumper have been given a coat of red paint, while the headlights now feature black colored bezels. In profile the 2015 370Z NISMO shows off its redesigned side sills, new mirrors and 19-inch Rays alloy wheels.
At the rear of the car Nissan have swapped out the previous car’s spoiler and replaced it with a smaller unit which actually produces more downforce. It also works in conjunction with the new front bumper to create downforce which is more evenly distributed over the front and rear axles.

The Sector 111 Project Dragon track car was first announced back in December of 2013. But at the time it was just a body-less functioning prototype. Well now it has a body, and a scheduled production date.
Based on the Palatov Motorsport D2 chassis, the Sector 111 Project Dragon is powered by a GM-sourced LS3 V8, tuned to produce 430 horsepower and 424 lb-ft of torque. The transmission is lifted from a Porsche 911, and to keep it old-school, there are no electronic driver aids, including traction control, stability control, or even ABS.
The target weight for the car is 1,800 lbs (816 kgs). That’s not superlight as far as stripped-down track cars go, but it’s lighter than the D2 on which it is based. And considering the size and output of the engine, the power-to-weight ratio should be excellent.

Dodge and SRT designers and engineers have gone all-out and created a four-door sedan with supercar humbling straight-line performance. The 2015 Dodge Charger SRT Hellcat is the fastest and most powerful production sedan in the world. It’s powered by a massive 6.2 litre supercharged Hemi Hellcat V8 engine churning out an enormous 707 horsepower and 650 lb-ft of tarmac rippling torque. Connected to a heavy-duty 8-speed automatic transmission, the engine is capable of catapulting the car from 0-60 mph in 3.7 seconds, it posts a quarter-mile time of 11-seconds dead, and it has a jaw-dropping 204 mph top speed.
The drivetrain used in the Charger SRT Hellcat is identical to that found in its two-door stablemate, the Challenger Hellcat, yet interestingly the Charger has a 5 mph higher top end, but a 0.2 second slower 0-60 mph time.

McLaren’s new 650S model now comes in three flavors, the standard road going 650S, the competition-spec 650S GT3 for serious racers, and now there’s the 650S Sprint which is aimed at track enthusiasts who still want a little bit of comfort. The 650S Sprint also replaces the MP4-12C-based 12C Sprint as McLaren’s track toy for the super-rich.
Compared to the road model, the 650S Sprint features increased downforce and better cooling airflow to the 3.8 litre twin-turbocharged V8. It also features a competition-spec fuel tank and quick-fill cap, a larger radiator borrowed from the GT3 car, a new hood with additional cooling ducts for the radiator, front wing louvres for improved airflow, reduced ride height and recalibrated damping and spring rates, 19-inch center-locking race wheels with either Pirelli slicks or wet tires, onboard air jack system, and an upgraded braking system.

Australian automotive news site, themotorreport.com.au, is reporting that in an interview with Mazda Australia’s boss, Martin Benders, he revealed that the new MX-5 “will look nothing like” the current car.
When pressed on more specific details of the 2015 MX-5 – which is due to debut in September – Benders said the new car would feature an evolved version of the ‘Kodo’ styling language used on the current 2, 3, 6 and CX-5 models. However he was understandably careful not to reveal too much information regarding the new design.

There are a number of so-called ‘reverse trikes’ or 3-wheelers on the market, including the classically styled Morgan Three Wheeler, the sports car-like Grinnall Scorpion III, F1 car-like Scorpion Prodigy P6, the more motorcycle-like T-REX and the electric-powered Epic EV Torq. At the same time there are also a few yet-to-be-realised projects from major manufacturers, like the Volkswagen GX3 and the Peugeot 20Cup.
And now there’s the Polaris Slingshot. Polaris are better known for their range of quads, snowmobiles and off-road vehicles, as well as their Victory and Indian line of motorcycles. But now, not content with offering vehicles with two wheels, vehicles with four wheels, and vehicles with tracks, they’re splitting the difference and offering a 3-wheeler too.

If you want a brand-new fifth-generation SRT Viper convertible, then you’re out of luck, as it only comes in coupe form. But now Michigan-based automotive engineering and prototype design company Prefix has rectified this by developing their own convertible Viper.
The conversion, called the Medusa Roadster (Manufactured, Engineered, Developed in the USA), costs $35,000 – on top of the price of a brand-new Viper. Prefix say they initially have plans for a run of just 10 cars, each with its own limited edition badge. The Medusa Roadster was debuted at a special event for 500 Viper owners and enthusiasts who were treated to a surprise unveiling of the car.

What you’re looking at here is the Aston Martin V12 Vantage S Roadster, the fastest series production convertible to leave the Aston Martin factory. Mechanically identical to the V12 Vantage S Coupe, the Roadster uses the same AM28 6.0 litre naturally aspirated V12 engine, a powerplant which produces 565 horsepower and 457 lb-ft (620 Nm) of torque. It allows the car to accelerate from 0-62 mph (100 km/h) in just 4.1 seconds, and continue on to a top speed of 201 mph.
Like its hard top sibling, the V12 Vantage S Roadster also uses the same three-mode adaptive damping suspension system which offers Normal, Sport and Track settings. It also employs carbon ceramic brake discs and uses the same ZF Servotronic power assist steering.
The transmission is a seven-speed Sportshift III hydraulically actuated automated manual unit which provides motorsport-style paddle shift changes. It replaces the six-speed manual unit used in the V12 Vantage Roadster, and also weighs 20 kgs (44 lbs) less.

The 2015 Dodge Challenger SRT Hellcat, the supercharged top-of-the-line Challenger, will be the most powerful production muscle car when it goes on sale later this year. That’s because its supercharged 6.2 litre HEMI V8 engine manages to produce 707 horsepower and 650 lb-ft of torque.
However Dodge understand that over 700 horsepower is going to test even the most experienced driver, so just to provided an additional level of security, the car comes with two different keys. The black key allows the engine to produce a slightly more reasonable 500 horsepower maximum output. While the red key unlocks the full 700. Either way, I’m willing to put money on the fact a good number of Challenger SRT Hellcats get some impromptu bodywork modifications thanks to drivers who overestimate their driving talents and ability to cope with supercar-worrying power in a heavier car with a less exotic and capable chassis.

Just in case you thought there weren’t enough British-built lightweight track-focused sports cars on offer, Elemental Cars, based in Surrey, have come to the rescue with the Elemental RP1.
The Elemental RP1 offers much the same as the competition. It’s as light as reasonably possible, highly tunable and customisable, and offers just the bare minimum of comfort and day-to-day practicality. It’s one of the better looking two-seat track cars out there, and it looks like someone with a design degree has been allowed to make the decisions regarding styling. In fact that someone is Guy Colborne, and he’s worked on projects for Pininfarina, BMW, Opel and Ford, as well as acting as a visiting lecturer for the Vehicle Design course at the world renowned Royal College of Art.
It’s also clearly been engineered by people who understand what amateur racers and track-day enthusiasts want. The team is made up from a number of racecar and supercar engineers, guys who have worked on vehicles like the McLaren 12C and P1 and who have provided their expertise to F1 teams and aircraft manufacturers. The Elemental RP1 isn’t something which has been knocked up by someone with a welder and a few spare rolls of fiberglass.
