New Mercedes-AMG A 45 And CLA 45 Pack Supercar Performance In A Compact Body


Mercedes has finally pulled the covers off the new A45 and CLA45 AMG models at the Goodwood Festival of Speed.

The new baby AMG models arrive with some seriously impressive figures that are set to redefine their class; both are powered by the turbocharged 2.0-liter M139 four-cylinder engine with up to 415hp (421PS), a 0-62mph (100km/h) in as little as 3.9 seconds and a headline-grabbing Drift mode.


As before, customers will get to choose between two versions; the basic 45 model, which offers 382hp (387PS) and 354lb-ft (480Nm) of torque, and the more powerful 45 S with its 415hp (421PS) and 368lb-ft of torque.

All models come fitted with the new eight-speed AMG Speedshift dual-clutch transmission and the fully variable Performance 4Matic+ all-wheel drive system. The basic A 45 model can achieve a 0-62mph (100km/h) in 4 seconds flat (CLA 45 in 4.1 sec) while the A 45 S requires just 3.9 seconds for the same procedure (CLA 45 S in 4.0 sec). Top speed for the basic 45 models is electronically capped at 155mph (250km/h), with the S variants able to go all the way up to 167mph (270km/h).


The bodyshell of the new AMG 45 models is reinforced to provide a stiffer basis for the suspension; AMG engineers have added a lightweight aluminum plate underneath the engine, which supplements the also new front tower brace. Additional reinforcing plates can be found between the side members and the A-pillars, while diagonal struts at the front and rear of the underbody make the shell even more rigid.

The highlight in the Performance 4Matic+ all-wheel drive is the inclusion of the new AMG Torque Control system, which is housed in the rear differential; the system uses two electronically controlled multidisc clutches, one for each rear drive shaft, controlling the amount of torque sent to each individual rear wheel with much greater precision.


The much advertised Drift mode is standard on S models and part of the optional AMG Dynamic Plus package for the standard models. As with the bigger AMG V8s, the new Drift mode can be engaged when the ‘Race’ driving mode is selected, the ESP is deactivated and the transmission is in manual mode.

The new AMG 45 powertrain comes with six driving modes: Comfort, Sport, Sport+, Slippery, Individual and Race. The latter is optional on standard models.


Sales of the new 2020 Mercedes-AMG A 45 and CLA 45 are expected to begin by the end of this year.

New Mercedes-AMG GT Roadster & GT C Roadster Officially Revealed [w/Video]

Image
Mercedes finally pulled the wraps off the  AMG GT’s Roadster version  which will come in two flavors: the basic 469hp model and the range-topping 547hp GT C model. The rumors were true then, as the new AMG GT C Roadster not only offers 46hp more than the AMG GT S Coupe but also borrows some of the technology found  in the manic AMG GT R .  More specifically, the new AMG GT C comes with the GT R’s rear axle steering, electronic locking differential and a wider rear track. Torque is rated at a peak 501lb-ft (680Nm), available from just 1900rpm. Mercedes reckons it needs 3.7 seconds to hit 62mph from a standstill, with the top speed electronically limited to 196mph (316km/h). The AMG GT Roadster on the other hand requires 4 seconds flat for the 0-62 procedure and won’t stop accelerating before hitting 187mph. Both models are powered by the same twin-turbo 4.0-litre V8 engine that has become the spine of AMG’s range, powering almost everything wearing their badge. As in the Coupe, a sev

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

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
