Hyundai has announced plans to highlight its new high-performance sub-brand, known simply as ‘N,’ at the Frankfurt Motor Show.

The Korean automaker will preview its latest World Rally Championship racer, based on the New Generation i20. Prototype cars are already undergoing testing and late development toward final rally-spec for the 2016 season.

The company will also bring its Hyundai N 2025 Vision Gran Turismo concept (pictured) to the show. Designed for virtual use in the popular video game series, the radical concept presents a “perspective on future performance characteristics.”

The Veloster-based RM15 concept, initially unveiled at the Seoul auto show in April, will also be on display in Frankfurt. Hyundai claims the mid-engine hatchback, which boasts 300 horsepower, is said to represent how Hyundai’s N technologies could come into production.

Recent rumors suggest Hyundai could also reveal its first production-bound N car in Frankfurt. It is expected to be based on the Euro-spec i30, but outfitted with the RM15′s powerful engine and all-wheel drive.

Additional official details could be released ahead of the September show.

10 manufacturers have been named in a lawsuit brought by representatives of consumers who claim keyless ignition systems pose carbon monoxide poisoning risk to users.

The suit claims manufacturers failed to disclose the health risks posed by keyless ignition systems that allow the engine to continue to run after the fob has been removed from the vehicle. The plaintiffs allege that 13 deaths have resulted from carbon monoxide poisoning under these circumstances, according to Reuters.

The manufacturers named in the suit are Bentley, BMW, FCA, Ford, GM, Honda, Hyundai, Kia, Mercedes-Benz, Nissan, Toyota and Volkswagen.

Plantiffs are seeking damages and an injunction against the automakers forcing them to implement a timed shut-off that prevents vehicles from running indefinitely after the key has been removed.

This is not the first time keyless ignitions have been the focus of a safety controversy. During the Toyota “unintended acceleration” debacle, regulators raised concerns over the amount of time it takes to shut off a car with push-button start.

After years of masquerading as the CL, Mercedes-Benz has renamed its flagship coupe to more accurately reflect its roots for the latest model year. Enter the 2015 S550 4MATIC Coupe.

But despite the name change, the blueprint for Mercedes’ S-Class-based coupe remains very much the same — an opulent interior wrapped in a stylish two-door body shell. And for the 2015 redesign, that ethos is more steadfast than ever.

What is it?
As its name implies, the S-Class coupe is essentially a two-door version of Mercedes’ S-Class sedan. However, for the coupe treatment, Mercedes lopped off 8.7-inches of wheelbase, leaving the S-Class coupe 8.6-inches shorter overall than its four-door counterpart. Despite its tighter proportions, the S-Class Coupe is actually about 77 pounds heavier than the S-Class sedan thanks to extra body bracing required for the car’s pillarless window treatment.

The S550 4MATIC model seen here is the entry point into the 2015 S-Class Coupe lineup. It’s powered by a 449-horsepower version of Mercedes’ 4.7L biturbo V8 that sends power to all-four wheels via a seven-speed automatic transmission.

Two AMG versions of the S-Class Coupe are also on offer for 2015. The S63 AMG uses Mercedes’ 5.5L turbocharged V8 and is good for 577 horsepower and 664 lb-ft of torque. The full-boat S65 AMG gets a twin-turbocharged V12 that generates 621 horsepower and a Herculean 738 lb-ft of torque.

What’s it up against?
The 2015 S-Class Coupe rubs elbows with well-heeled competitors like the BMW 6-Series Coupe, Bentley Continental GT and Aston Martin DB9.

What does it look like?
From the A-pillars forward the S-Class Coupe shares similar styling with its sedan stablemate, but the two vehicles aren’t exact carbon copies.

The Coupe is much more stub-nosed than the four-door S-Class, with a radiator grille design more inline with the AMG GT sports car. The S-Class Coupe’s headlights have also been redesigned and moved farther back, further accentuating the car’s GT-inspired nose treatment. Reflecting its more sporting nature, the S-Class Coupe features larger air inlets in its lower bumper than the S-Class Sedan.

In profile the S-Class Coupe is long and lean, and that’s not just because Mercedes erased the two-rear doors. Compared to the sedan, the coupe’s roofline sits about three-inches lower. Flared sills also help to keep the Coupe visually planted to the ground.

The rear of the S-Class Coupe is a total deviation from the sedan, with wide taillights replacing the up-right units found on the four-door. The trunk lid has also been re-sculpted, with the license plate inset moving to the lower bumper. Rectangular dual exhaust outlets are carryover from the sedan.

Our test car was also equipped the Edition 1 package, which added upgrades like Swarovski crystal headlamps and 20-inch AMG wheels.

Thanks to the small but critical design changes from the sedan, the S-Class Coupe exudes the kind of presence the old CL could only dream of. To our eyes, the S-Class Coupe is the best looking vehicle in the Mercedes lineup.

And the inside?
The story is much the same on the inside, with the two S-Class models sharing the same basic layout. However, there are a few key differences.

The dash of the Coupe is more contoured, with the upper section featuring a curved inset while the lower section protrudes slightly. That added depth and dimension makes for a more immersive cockpit that’s befitting of a personal luxury coupe.

The steering wheel in the Coupe has three-spokes versus the two-spoke unit in the Sedan. We far prefer the Coupe’s tiller, which doesn’t look like the smiling mouth of a clown.

Other than those styling revisions, the interior of the Coupe is largely similar to the Sedan, which isn’t a bad thing.

Two large LCD screens dominate the upper section of the dash, providing everything from vehicle speed to a night vision display to the car’s owner’s manual. Mercedes’ latest COMAND infotainment system is along for the ride, which now includes a touchpad in addition to the dial wheel located in the center console. Overall the system is logically arranged and easier to use with the new touchpad, but the graphics for the system are starting to seem a little dated. The screens themselves, however, offer excellent resolution.

The S550 Coupe’s voice control, which was a strong point in the S550 Sedan we tested a couple of years ago, was a little less impressive. It took several tries for the system to locate our desired POI. We’ll give the system the benefit of the doubt, though, since it worked very well in past evaluations.

Toggles switches for the Coupe’s ventilation system are well laid out and easy to use. We also appreciated redundant switches in the center console that offered quick access to vehicle settings and the front seat massagers, which we used on virtually every trip. Our noses were even in the lap of luxury during our week with the S550 thanks to an integrated air freshening system.

Our tester’s interior was lifted visually and auditorily thanks to an optional Burmester High-End 3D Surround Sound System. The system includes beautifully crafted aluminum speaker grilles throughout the cabin and a sound worthy of the ‘High-End’ tag. However, that added luxury doesn’t come cheap, with an MSRP of $6,400.

Materials throughout the S-Class Coupe are nothing short of top-notch. Every surface you touch is covered in either leather, wood or aluminum. Even some places that you’ll never lay a finger, such as the shelf behind the rear seats, are beautifully covered in leather with contrasting stitching.

Our only real design complaint lies with the S-Class’ silver buttons on the doors, console and steering wheel. In addition to looking a bit cheap, they can also be difficult to read in direct sunlight.

Although down on wheelbase, the S-Class Coupe still offers a decent amount of legroom from rear seat passengers. Ditto for headroom.

But does it go?
Though technically the baby in the S-Class family when it comes to performance, the S550 is no slouch. Equipped with Mercedes’ twin-turbocharged 4.7L V8, the S550 belts out a very respectable 449 horsepower and 516 lb-ft of torque. The S550 pushes that power to all four-wheels via a seven-speed automatic transmission.

Despite weighing more than 4,700 pounds, the S550 can still shift, with Mercedes claiming a 0-60 time of 4.5 seconds. Just a few years ago that was supercar territory.

But if you’re considering the S550 for its performance, you’re buying this coupe for the wrong reason. The S550 4MATIC Coupe shines as a classic GT car, munching up the miles while keeping you supremely comfortable in a leather-cover arm chair that offers six different massage settings. The standard AIRMATIC air suspension soaks up the bumps to the point that you’re not entirely sure if your driving or floating on a cloud.

The AIRMATIC system does have a Sport setting that firms everything up, but it just feels like you’re asking the car to do something that it doesn’t want to, like asking a gentleman in a tuxedo to run a hundred-yard dash. We do, however, suggest using the Sport drivetrain mode as throttle just isn’t very responsive in Eco mode.

And although the S-Class isn’t the most sporting coupe on the block, it’s happy to remind you of the power that resides under hood. A press of the throttle results in a subtle but satisfying whistle from the turbos and a V8 bark from the exhaust.

The S550 isn’t fully autonomous, but it does a very convincing impression of a self-driving car. With the optional DISTRONIC Plus with Steering Assist system engaged, our tester could keep pace with traffic ahead while steering itself around moderate curves. Of course the system encourages you to keep your hands on the wheel with a dashboard warning.

Of note, you should familiarize yourself with the DISTRONIC controls before you set off as they are inexplicably hidden on a stalk behind the steering wheel.

A night-view camera is available and can help pick out pedestrians hiding under the cover of darkness. On well-lit city streets the system is of dubious use, but we could see the system being handy for those that routinely traverse rural roads.

The EPA says to expect 16mpg in the city and 24mpg on the highway from the S550 4MATIC Coupe, netting a combined average of 19mpg. We must have been a little heavy-footed during our time with the S550 as we could only muster about 12mpg.

Leftlane’s bottom line
We won’t be as brash to call a $150,000 car a bargain, but the S550 4MATIC Coupe is quite the value compared to its competition. Even when equipped to the gills the S550 is still 40 grand less than a DB9 or a Continental GT. And looking out from the massaging front seat of the beautifully styled S550 Coupe, we can’t really see why anyone would want to spend more to get less.

Rumors surrounding Nissan’s next Z car have shifted once again, as a fresh report points to a crossover as the most likely candidate.

The company had been considering a smaller car, potentially inspired by the retro-styled IDx concepts or serving as a spiritual successor to the original 240Z. Execs have now settled on a different approach, namely a sporty compact crossover, unnamed sources have told Autocar.

Nissan already offers a Nismo-tuned Juke, however the Z-badged crossover is expected to bring a more traditional appearance. It could be closer in form to the global-market Qashqai (pictured), but in a smaller package.

The latest report speculates that a Z crossover will feature a streamlined profile with little headroom for rear-seat passengers. It is unclear if it will be presented as a coupe-like two-door model or in a four-door configuration.

A production model would likely be built upon Renault-Nissan’s CMF-B platform and outfitted with several different small-displacement turbocharged engines. Hybrid powertrains are also mentioned as a possibility.

Nissan is expected to test the waters with several concept vehicles, the first of which could appear next month in Frankfurt.

The Ford Mustang, once a forbidden fruit for those residing outside of North America, is proving to be a popular option for UK petrol heads.

Since Ford’s UK arm began taking orders for the first of its kind right-hand-drive Mustang in January, the automaker has racked up 2,000 orders. Of those initial hand raisers, 80 percent have opted for the coupe over the convertible. Perhaps more interestingly, a full 70 percent have sprung for the Mustang’s optional 5.0L V8 over the car’s standard 2.3L EcoBoost four-cylinder. That’s quite the take rate given fuel prices in the UK.

Just over half of those Mustang orders, 55 percent, have been for the six-speed manual. The other 45 percent of Mustang buyers have opted for the car’s six-speed automatic transmission.

It should come as little surprise that the vast majority of Mustangs are being built in enthusiast’s spec. Buyers in the UK have been unable to purchase the Mustang for the last five decades, and there is clearly pent up demand for the rortiest version of the iconic pony car.

The Mustang EcoBoost carries a base price of £29,995 in the UK, while the V8-powered GT goes for £33,995. Right-hand-drive Mustangs are currently rolling out of Ford’s Flatrock Assembly Plant with the first UK deliveries slated for November.
