454HP BMW M4 CS Revealed, Slots Below The GTS


We all knew it was coming and at the Shanghai Auto Show, BMW has unveiled the M4 CS, a potent variant that slots between the M4 Competition Package and the range-topping M4 GTS.

While BMW hasn't gone into specific production numbers, it's believed that as with the GTS, production of the M4 CS will be capped, as the Germans will manufacture the special edition only until the middle of next year,

Being that the production run of the GTS has already concluded, the CS is now the most potent M4 in the company's range.

The modifications start with the engine. BMW's M division has tweaked the familiar 3.0-liter twin-turbocharged inline-six engine to now deliver 454 hp and 442 lb-ft (600 Nm) of torque. Those figures represent a 29hp and 37 lb-ft leap over the standard M4 and are 10 hp and 37 lb-ft more than the M4 Competition package.

BMW has also taken inspiration from the GTS by employing a number of weight saving measures for the M4 CS. They include the roof, trunklid spoiler, diffuser and front splitter all being made from lightweight carbon fiber reinforced plastic. Additionally, new lightweight door trims have been fitted alongside door pull loops. This results in a 32 kg (71 lbs) weight saving over the M4 and 10 kg (22 lbs) over the M4 Competition Package.

When working in conjunction with the standard dual-clutch seven-speed automatic transmission, the weight savings and extra grunt propel the M4 CS from 0-62 mph (100 km/h) in a mere 3.9 seconds, 0.3 seconds quicker than the M4 Competition Package. The top speed meanwhile sits at a limited 174 mph (278 km/h). BMW says that it lapped the 'Ring in 7 min and 38 seconds, which makes it slower than the GTS (7:27.88), and just as fast as the Porsche 991 Carrera S.

Other mechanical modifications to the CS include optional 6-piston front and 4-piston gold calipers with carbon ceramic brakes, stiffer springs and dampers, larger roll bars and 19-inch front and 20-inch rear wheels as standard. The car also gets the same 80 mm (3.1-inch) tailpipes as the M4 Competition Package.

Customers will be able to opt between exterior colors including Lime Rock Grey metallic, Alpine White, San Marino Blue metallic, Sapphire Black metallic and Frozen Dark Blue II.

In Germany, the BMW M4 CS will be priced at €116,900 or €40,200 more than the regular M4 Coupe that starts at €76,700. US and Canadian pricing have yet to be announced, but expect the CS to cost over $100,000 when it lands in North America in early 2018.

Limited Edition Ford GT 'Competition Series' Is All About The Track

Image
Ford's new GT Competition Series was built with weight-saving in mind, but also with an improved center of gravity for better road-holding. Among its features, you'll notice the lightweight carbon fiber racing stripes, A-Pillars and side mirrors, as well as the unique race-inspired Perspex acrylic engine hatch with integrated venting. Thanks to the manual latch and the carbon fiber prop rod, weight near the roof has been reduced, though Ford engineers went even further in their quest to make the car lighter, by making the bulkhead Gorilla Glass behind the driver about half as thick (and as light) as on other models. "The Ford GT has racing in its blood," said Ford exec Raj Nair, while adding that the Competition Series "was developed with the most hardcore track enthusiasts in mind, providing a tailored set of lightweight features and unique livery to match." There are also plenty of remaining performance features from the production car, such as ...

Volkswagen T-Roc Cabriolet Is A Crossover For Droptop Lovers

Image
Droptop crossovers have always been rather odd and the T-Roc Cabriolet is no different. It will be the only convertible Volkswagen on sale for the foreseeable future and will celebrate its public debut at the Frankfurt Motor Show in September. Rather than simply removing the roof of the standard T-Roc, Volkswagen has drastically altered the vehicle’s structure and body. In fact, its wheelbase is 37 mm longer than the standard T-Roc while its overall length is up by 34 mm. In addition, the Volkswagen T-Roc Cabriolet features structural strengthening in the underbody, side panels, cross members, doors, and windscreen frame to make up for the lack of a roof. The folding fabric roof developed by Volkswagen retracts in just nine seconds at speeds of up to 19 mph (30.5 km/h) and is similar in operation to the roof of the outgoing Golf Cabriolet. The presence of the soft top reduces trunk space by 161 liters down from the 284 liters of the run-of-the-mill T-Roc. We don’t think bu...

Alpine A110 Hits Geneva With Pure, Legende And GT4 Versions

Image
Renault’s reborn Alpine brand has been getting rave reviews for its new A110 and now, as promised, it’s revealed new versions of its coupe at the Geneva Motor Show. Following the success of the sold-out Premiere Edition, the A110 will now be offered in Pure and Legende trims. The A110 Pure is targeted at driving enthusiasts. It features one-piece Sabelt sports seats that weigh barely more than 13 kilograms (28.6 pounds) each and, combined with other weight-saving measures, helps keep the curb weight below 1,100 kg ( 2,425 lbs). It’s not entirely stripped out, though, and still comes with features like air-conditioning and satellite navigation. Buyers can also add upgraded Brembo brakes and an adaptive exhaust system and can upgrade to the adjustable comfort seats. Those come standard on the Legende model, which is geared more towards every day driving and grand touring and comes with leather upholstery. Customers can also choose between two Focal sound systems and two wheel...
