Porsche 911 Turbo and Nissan GT-R Nismo star in World's Greatest Drag Race 4

We love Motor Trend's annual World's Greatest Drag Race video. Now back for its fourth appearance, the idea of lining some of the world's fastest cars up for a ten-wide, straight-line, full-throttle run is, well... it's pretty freaking badass.
The lineup this year boasts some impressively fast cars to be sure. The group of ten includes the following darlings: Alfa Romeo 4C, BMW i8, BMW M4, Chevrolet Camaro Z/28, Ford Fiesta ST, Jaguar F-Type R Coupe, Nissan GT-R Nismo, Porsche 911 Turbo S, Subaru WRX STI and, last but not least, the Volkswagen GTI. Give us any one of those for the weekend, and we're happy to take the keys.
It must be said though, that for a publication that draws as much water as Motor Trend does, there are some big cars that we might expect to be here instead. The Lamborghini Huracán or Ferrari 458 Speciale would have added some exotic flare to the list, and the omissions of the Chevy Corvette Stingray (for the second year in a row) and the Dodge Challenger Hellcat are real head-scratchers.

2015 BMW M4 Convertible is here to put wind in your sails

Each generation of the BMW M3 has included a convertible model. Even the distant E30, the patriarch of the M3 line, had an ultra-rare (only 787 were built) droptop model. The convertible became more common on the successive generations, with the hardtop-convertible E93 being the most recent. Considering this history, there seemed very little doubt that as the M3 became the M4, a convertible would be in the cards. Now, the new droptop has arrived.
Set for its global debut at the 2014 New York Auto Show, the 2015 BMW M4 Convertible features, like its forbearers, everything that's great about the hardtop variant while adding an unlimited amount of head room. That means the same 3.0-liter, 425-horsepower, 406-pound-foot, twin-turbocharged straight six sits under its domed hood, while either a six-speed stick or a seven-speed M dual-clutch transmission dispatches power to the fat rear tires.
As for specific differences between the hardtop and the new convertible, obviously, the droptop is heavier. A lot heavier. Where an M4 with a six-speed manual tips the scales at 3,530 pounds, the M4 Convertible weighs in at 4,055 pounds. Believe it or not, BMW has actually trimmed 90 pounds from the last-generation M3 convertible, code-named E93. This marginal weight reduction from the third-generation convertible to the fourth is barely half of the 174 pounds BMW was able to subtract when transitioning from M3 Coupe to M4 Coupe.

BMW 4 Series spied with its future competition

BMW showed off its new 4 Series coupe in concept form at the 2013 Detroit Auto Show earlier this year, but it won't be long before we see the production model, evidenced by this modestly camouflaged prototype spotted testing. In case you forgot, the 4 Series serves as the replacement for the two-door versions of the BMW 3 Series, just as the upcoming 2 Series will effectively be the new version of the 1 Series coupe and convertible sold in our market.
This isn't our first glimpse of the 4 Series out testing, and we've even spied its droptop, Gran Coupe and too-hot M4 kin. We don't expect the final design to stray too much from the concept car seen in Detroit, albeit without the normal conceptual goodies like oversized wheels and with the overstyled front fascia toned down a bit. Our spy photographers even caught the 4 Series coupe hanging out with an Audi A5, giving us a good glimpse at how the two cars will stack up in terms of size and design.
It's still unknown exactly what engines will power the car when it comes to production, but since this thing is a derivative of the 3 Series, we expect the usual range of turbocharged four- and six-cylinder engines to be available, likely in 428i ad 435i guise (though, to be fair, the larger 640i coupe uses a 3.0-liter turbo engine, so there's even the potential for 440i nomenclature to work its way into the mix). We'll have to wait until the car officially bows later this year to know for sure.
