Zarooq SandRacer 500 GT

Today's supercars are a far cry from the temperamental, overheating, cramped, barely-streetable cars of the past. Some of them even have cupholders. But none of them would even think about putting one Z-rated tire on any surface that isn't pavement. The Zarooq SandRacer 500GT isn't one of these cars — if you can call it a car. The SandRacer aims to provide performance both on and off-road, with the driver being able to engage a "sand" mode that lifts the body, providing a healthy dose of ground clearance for getting over those pesky dunes. 525 horsepower is on tap from a 6.2 liter V8, and the lightweight chassis and roll cage designed by Campos Racing keep the knobby tires on the ground. Only 35 are being produced.

Aston Martin Valkyrie Hypercar

Although it's still under development — the company says it's "95% of the way there" with the exterior — the latest Aston Martin Valkyrie Hypercar images are worth a look. The current design, developed in collaboration with Red Bull Racing, is heavily influenced by aerodynamics, with features like full-length Venturi tunnels, a teardrop-shaped cockpit, and openings in the body surface between the cockpit and front wheel arches which provide added downforce. Inside, the two seats are mounted directly to the tub in an F1-style "feet up" position, while nearly all the controls are mounted on the removable steering wheel, on either side of the embedded OLED display that serves as instrumentation. No release date has yet been set.

Aston Martin RapidE All-Electric Sports Car

Based on the Rapide AMR, the Aston Martin RapidE All-Electric Sports Car will be the British marquee's first foray into all-electric motoring. The car was first unveiled as a concept in 2015 and will be put into production for delivery in 2019. While specifics are scarce, we do know the vehicle will use technology developed in collaboration with Williams Advanced Engineering and will offer a unique driving experience compared to its V12-powered sibling. The four-door sports car will be limited to just 155 units.

Effeffe Berlinetta

Inspired by Italian racers of the 1950s and 60s, this brand-new car looks and drives like few automobiles on the road today. The two brothers behind this stunning piece of work, Leonardo and Vittorio Frigerio, started their company to bring classic design and modern technology like 3D printing and modeling, new alloys, and up-to-date safety features into one passion project: the Berlinetta. The car is powered by a rebuilt 1971 Alfa Romeo twin-cam 4-cylinder engine and a five-speed manual gearbox, delivering 180 horsepower at 6500 rpm to a curb weight of fewer than 1,800 lbs. With great power comes great braking and suspension, with discs on all four corners and an independent front suspension, with a live-axle link in the rear. Interior upholstery will be tailored to the buyer's tastes, and will even come with a matching luggage set. The sale price also includes some time on the track to get a handle on your new Italian roadster — and it should feel right at home hugging the corners and roaring across the line.

2018 Porsche 911 GT2 RS

54 years of 911 development have lead to this. Millions of miles over five decades on race tracks, rally courses, and everyday public roads were all a proving ground for the pinnacle of the storied 911 — the 911 GT2 RS. Put aside the fact that it's the most powerful 911 ever produced for a moment. The GT2 RS is also the most technologically advanced: a revised aerodynamic package, extensive use of carbon fiber and magnesium, world-class suspension, rear-wheel steering, and ceramic composite brake rotors. But the heart is, of course, the venerable flat-six motor. This revision displaces 3.8 liters and uses dynamic twin turbochargers to deliver a staggering 700 hp and 553 lb-ft of torque, enough to blast from naught-to-60 in 2.8 seconds with a top speed of 211 mph — the most ever from a street-legal factory 911. The GT2 RS won't be the final word on the 911, but it's the boldest yet from Stuttgart.

Porsche Dark Knight 911 Turbo S

The Porsche 911 Turbo S has a performance ceiling high enough for nearly any driver — but too much is never enough. Polish tuner Auto-Dynamics took the challenge of raising the bar for the 911 a few more notches with their 911 Turbo S Dark Knight. From the outside, the car features carbon fiber vented fenders, body skirt, hood, and spoilers, all in a menacing matte black and center lock wheels with yellow accents. Under the decklid, the flat-6 receives exhaust manifolds and piping from GMG Racing and TechArt, combined with a specialized intake that brings horsepower power up to nearly 700. The interior continues the exterior theme — black with yellow accents and a host of tech upgrades. Even if your evening routine doesn't involve keeping the streets safe, you'll feel like Bruce Wayne behind the wheel of AutoDynamics' Dark Knight.

Hennessey Venom F5

Named for the strongest of tornados capable of producing the fastest winds on Earth, the Hennessey Venom F5 aims to be just as quick. Built from the ground up with a unique chassis and design, the F5 has its sights set on beating the Bugatti Chiron for the title of world's fastest production car. To achieve it, the F5 will offer cutting-edge technology, an ultralight design, and a twin-turbo, American-built V8 that promises speeds of at least 290 mph — meaning it might also stake its claim as the world's first 300 mph supercar.

Audi R8 Spyder V10 Plus

The most powerful open-air production car ever from the four rings, the Audi R8 Spyder V10 Plus takes an already insanely quick ride and makes it even faster. Its 610 hp V10 produces 70 hp more than the standard model and is linked to a seven-speed S Tronic transmission and Quattro permanent all-wheel-drive. The result is a 0-62 time of just 3.3 seconds and a top speed of over 200 mph. The Plus comes with several other standard improvements, as well, including R8 bucket seats, a host of CFRP components, and an exclusive micrommata green paint option.

McLaren 570S Spider

If the McLaren 570S coupe doesn't provide enough fresh air at triple-digit speeds, the British supercar company has a fix for that — the 570S Spider. The retractable roof allows you to enjoy the sunshine and all of the performance of its fixed-roof sibling, with 562 horsepower on tap from its twin-turbo V8 and a 0-60 time of 3.2 seconds. The top retracts in an equally-impressive 15 seconds at up to 25 MPH, and McLaren's chassis expertise assures that there's no loss of structural rigidity from the hardtop. Even the top speed — a heady 204 MPH — remains unchanged, although that drops to only 196 with roof down. The McLaren 570S allows you to enjoy the summer without sacrificing an elite driving experience.

Porsche 911 Turbo S Exclusive Series

If Porsche's top-of-the-line 911 Turbo S doesn't satisfy your performance needs, the German manufacturer's Exclusive model definitely will. Building on the supercar-like abilities of the Turbo S, the Turbo S Exclusive pushes the limits of the 991 platform, with production limited to only 500 units worldwide. An increase of 27-horsepower over the base Turbo S brings the total to 607, dropping the naught-to-60 time to a blistering 2.8 seconds and on to a top speed of 205 MPH. The exterior of the car is finished in a stunning Golden Yellow Metallic paint with black racing stripes and accented wheels and brake calipers — a theme echoed inside with contrast stitching and copper thread worked into the carbon fiber trim. To make sure everything is on point once you exit the vehicle, Porsche is also offering a matching luggage set and Porsche Design wrist watch to buyers for a complete road-to-destination package.

BMW M4 GT4

Proven through over 20,000 miles of testing and hours upon hours in the wind tunnel, the BMW M4 GT4 is ready to be your next track car. Its twin-turbo inline six engine outputs over 430 hp, with the exact number depending on the car's power sticks, which offer plug-and-play changes in performance. The chassis includes a welded safety cage, while the majority of the body components — including the race-specific front splitters and rear wings — are made from carbon fiber reinforced plastic. Other tricks are borrowed from the top-of-the-line M6 GT3, making the GT4 a formidable challenger.

Shelby Wide Body Super Snake

Created to push the performance envelope of the 2015+ Mustang chassis, the Shelby Wide Body Super Snake is a track-focused concept. The wider track — four inches in the rear, and 2.5 up front — gives it improved traction, letting you brake later and accelerate earlier out of the corner. New front fenders and rear quarter panels accommodate the revised Cortex track suspension, bigger Brembo brakes help stop the 750 hp beast, and forged aluminum wheels reduce weight. Expected to go into production this fall, it will be available worldwide and indexed in the official Shelby Registry

One-Millionth Porsche 911

In the 54 years since the 911's introduction, few production cars have undergone such continuous development — and stayed as true to the original concept. The engine is still rear-mounted, and the exterior design can be traced back to the first 911 to roll off the production line. Now, Porsche has another milestone to add to an already overflowing trophy case. The One Millionth 911 drove off the assembly line in Zuffenhausen, an Irish Green Carrera S, complete with a commemorative plaque and a few unique features that hark back the first 911. Unlike virtually every other 911 in history, this one won't be sold, but will instead embark on a world tour before going on display at the Porsche Museum.

Dodge Challenger SRT Demon

One look at its muscular body tells you it's not a supercar. Yet the Dodge Challenger SRT Demon is certainly super... something. Powered by a new "Demon" variant of the company's supercharged 6.2L Hemi V8, it has 840 hp at its disposal. This power gives it the ability to move from 0-60 in just 2.3 seconds, making it the world's fastest production car in this metric — faster than even the Bugatti Chiron. It's also been banned by NHRA before it's even released, as it's also the world's fastest production car in the quarter mile, with a time of 9.65 seconds and a top speed of 140 mph. Technical wizardry was necessary to achieve these feats, including the SRT Power Chiller that uses A/C refrigerant to cool air entering the supercharger, an Air-Grabber induction system with the largest hood scoop you'll find on the lot, and the ability to run on 100+ unleaded high-octane fuel. Limited to just 3,000 units in the 2018 model year, with deliveries slated to begin this fall.

2018 Chevrolet Corvette Carbon 65 Edition

Built to celebrate the 65th anniversary of the Corvette, the 2018 Chevrolet Corvette Carbon 65 Edition gives the latest version a unique livery. A new Ceramic Matrix Gray paint color pairs well with the carbon fiber ground effects, hood section, intake ducts, roof, and spoiler, as well as with the blue graphics and brake calipers. Inside you'll find a carbon fiber steering wheel, carbon fiber trim, and blue contrast stitching on the Jet Black seats. Available exclusively on Grand Sport and Z06 models in both coupe and convertible variants and limited to just 650 numbered examples.

Aston Martin Vanquish S Red Arrows Edition

Inspired by the Royal Air Force's official aerobatic unit, the Aston Martin Vanquish S Red Arrows Edition resembles a ground-bound jet. As you'd expect, the exterior is clad in red, with white and blue carbon detailing, a white "smoke trail" on the side strake, and a carbon fiber roof panel with an inlaid "charge" pattern like you'd see on one of the jets' canopies. Inside, the sports seats receive Pinewood green inserts that recall a flight suit, green webbing seatbelts, and sills signed by the corresponding member of the squadron. Limited to just nine customer cars — as there are just nine members of the Arrows — with a tenth to be given to the RAF Benevolent Fund, the cars are available exclusively through Aston Martin Cambridge.

Kreisel Evex 910e

The Porsche 910 is a highly desirable piece of automotive history. The Kreisel Evex 910e reinvents the classic racer with eco-friendly propulsion. The 360 kW electric system lets the 2,400 lb car move from a standstill to 62 mph in just 2.5 seconds, on its way to a top speed of over 185. You can travel up to 215 miles per charge, and the battery can act as a bi-directional energy storage solution when it's plugged in at home. Best of all, it still looks like a 910, giving you the enjoyment of owning an iconic sports car and the benefits of a state-of-the-art powertrain.

Nissan 370Z Coupe Heritage Edition

The Datsun/Nissan Z-series doesn't celebrate its 50th anniversary until the end of the decade. The Nissan 370Z Coupe Heritage Edition gets the celebration started early. Adorned exclusively in Chicane Yellow or Magnetic Black liveries with special graphics and yellow trim on the interior, it recalls the original without giving up modern convenience. It's powered by a 332 hp 3.7L V6, hooked to either an Exedy high-performance manual or 7-speed automatic, giving it performance worthy of its namesake. Arriving at dealerships this spring.

Nissan GT-R Track Edition

Slotting in between the Premium and Nismo variations, the Nissan GT-R Track Edition is a new option aimed at the weekend warrior. Its hand-assembled twin-turbo 3.8L V6 engine keeps the 565 hp output of the Premium. It gains the front fenders and forged aluminum-alloy wheels of the Nismo, along with a dry carbon fiber rear spoiler, increased body shell rigidity courtesy of additional adhesive bonding, and a Nismo-tuned suspension. Inside, you'll find a unique red and black color treatment, complete with high-grip Recaro seats and a simplified switch layout. Available by special order only.

Techrules Ren Supercar

Turbines aren't just for jets anymore. The Techrules Ren Supercar uses a mix of proprietary turbine technology, batteries, electric motors, and a diesel engine to deliver serious performance. All combined, the TREV-based system produces 1,287 hp when all six motors are engaged, good for a 0-62 time of 2.5 seconds and a top speed of 198 mph. The unique, Giugiaro-penned design features a jet fighter-like canopy that raises backward to allow entry to and exit from the three-person cockpit, clad in Italian leather and denim from PT. The aerodynamic body and lightweight chassis are built primarily using carbon fiber and high-strength aluminum alloy, resulting in a highly capable car that redefines Chinese automotive performance.

Aston Martin Vantage AMR Pro

One of two inaugural models for Aston's new AMR performance brand, the Aston Martin Vantage AMR Pro takes its racing lineage seriously. The 500 hp produced by its GT4 race engine makes it the most powerful V8 Vantage ever made, with performance enhanced further by a racing-spec adjustable suspension, competition transmission mounts, and center lock wheels clad with Michelin Pilot Cup 2 tires. It shares not only its paint scheme — Stirling Green with lime green accents — with the V8 Vantage GTE racer, but also its hood and rear wing, while the front end was developed specifically for this model. Limited to a maximum of seven examples.

Lamborghini Huracan Performante

The Huracan was already an impressive piece of engineering. It only gets better with the Lamborghini Huracan Performante. At its heart is the most powerful V10 Lamborghini has ever produced, outputting 640 hp, and paired to a seven-speed dual clutch transmission. It's 40kg lighter than the next-lightest Huracan, with forged composite used in the front and rear spoiler, bonnet, rear bumper, and diffuser. A patented active aerodynamic system closes and opens flaps in the front, and rear providing added downforce or lower drag, and the stiffer suspension makes for an even more engaging drive. As a result, it can move from 0-62 mph in just 2.9 seconds and hit a top speed of over 200 mph, enough to lap the Nürburgring in just six minutes and 52 seconds.

Ruf CTR Supercar

Ruf Automobile made its name building cars on unmarked Porsche chassis, so it's no surprise that their first car engineered and designed in-house bears more than a passing resemblance to a 911. The Ruf CTR Supercar is far more than a knockoff, however. It has the world's first rear-engine carbon fiber monocoque chassis, a 3.6L twin-turbo flat six engine producing 700 hp, a six-speed manual to help send that power to the rear wheels, and a carbon fiber body to help reduce weight. All of that combines in eye-popping performance, including a 0-60 time of 3.5 seconds and a top speed of over 220 mph. Built in Germany, production will be limited to just 30 units.

Fittipaldi EF7 Vision Gran Turismo

Racing legend Emerson Fittipaldi has for years dreamed of sharing the feeling of driving a championship race car. With the Fittipaldi EF7 Vision Gran Turismo, he finally gets his wish. Meant for drivers of all skill levels, it has a lightweight, shark-inspired carbon fiber body designed by Pininfarina. Its chassis is also made from carbon fiber, while Germany's HWA developed the powerful naturally aspirated V8, integrated gearbox, suspension, and braking system. The result is a visually arresting, visceral supercar worthy of the Fittipaldi name.

2018 Porsche 911 GT3

Porsche's commitment to making road-legal track cars continues with the 2018 Porsche 911 GT3. Under its skin sits a naturally aspirated 4.0L flat-six based on the one used in all 911 race cars. It produces 500 hp, enough to propel the car — when equipped with the standard seven-speed dual clutch transmission — from 0-60 in 3.2 seconds and hit a top speed of 197 mph. The redesigned lightweight chassis includes Rear Axle Steering, which steers the rear wheels in either the same or opposite direction as the front, depending on the speed, while the carbon fiber wing provides additional downforce. The interior is racing-focused yet still comfortable, with a GT Sport steering wheel borrowed from the 918, sports seats, and an advanced CarPlay-compatible infotainment system with the ability to deliver detailed driving data to your phone.

McLaren 720S

The second entry in its core Super Series lineup, the McLaren 720S makes many strides over the 650S, yet retains the company's signature aerodynamic look. Its twin-turbocharged, 4.0L V8 produces 710 hp and is mounted in the middle of its carbon fiber chassis. Paired to a seven-speed SSG transmission, it propels the car from 0-60 in 2.8 seconds on its way to a top speed of 212 mph. That speed is harnessed from inside a refined interior, outfitted with premium leather, aluminum switches, and enough creature comforts to make this as fun to drive on the road as it is on the track.

Alpine A110

After an absence of over two decades, Renault's racing brand is making a comeback with the Alpine A110. It gets its name — and its basic silhouette — from the legendary lightweight rally racer of the '60s and '70s. Details are still forthcoming on the new model, but we do know that it houses a turbocharged four-cylinder engine and moves from 0-60 in 4.5 seconds, placing it in line for competition with the Alfa Romeo 4C and the Porsche 718.

Robocar Driverless Race Car

Designed by automotive futurist Daniel Simon and outfitted with a bevy of cameras, sensors, Lidar, and Radar systems, the Robocar Driverless Race Car promises autonomous driving at high-speeds. The car will run in the Roborace, a series of global driverless racing events. A 540kW battery and four 300kW motors provide power, carbon fiber makes up most of the chassis and body, and it's "driven" by a Nvidia Drive PX2 brain capable of 24 trillion operations per second. Combined with advanced algorithms, it should be capable of navigating circuits at speeds of over 198 mph, making for compelling racing without the need for a driver.
