Want a Fast Mercedes-Benz that this the price of Ford Mustang 5.0??
You may Lost HP but gain a family car with Medium amount of HP.
the least flattering sense, you might call it the cheap Mercedes-Benz AMG. It's the first AMG product created on a front-drive platform and the first with a four-cylinder engine. Mercedes calls the CLA 45's 2.0-liter, direct-injection turbo the most powerful four-cylinder ever manufactured in serial production.
The engine block is the same one used in the standard CLA250. Including AMG's Nanoslide plasma spray cylinder bores. The cylinder head starts with an entirely different casting, using more expansive coolant passages. Piezo injectors are crucial to the CLA 45's output. A twin-scroll turbocharger with a whopping 26 pounds of boost and an expansive air-to-liquid charge cooler, then spills out through 3-inch downpipes on the headers.
The net effect in the CLA 45 is 355 hp at 6000 rpm and 332 lb-feet of torque, starting at 2250 rpm and holding steady through 5,000. That divides to 178 hp and 166 lb-ft per liter of displacement. And still the CLA 45 engine meets the forthcoming Euro 6 emissions standard three years before mandate. It also delivers 34 mpg in the European fuel-economy cycle, though EPA ratings are pending.
The seven-speed Speed-shift trans-axle is similar in design and concept to the dual-clutch automatics in other AMG products, packaged in a case for transverse application. Gear ratios are higher across the board than those in the CLA250, with three overdrive gears on top, and the CLA 45's final drive ratio is nearly 50 percent lower. The CLA the 4Matic all-wheel-drive system is fairly simple, but effective. A power-takeoff on the trans-axle constantly turns a drive shaft to the rear axle.
Default torque delivery is 100 percent front. Depending on several variables, including vehicle speed; lateral and longitudinal acceleration; steering angle; friction differences between wheels and accelerator position, the rear differential will engage and power up the rear wheels -- typically dividing torque 50-50, but, for brief bursts on extreme low-friction surfaces, it can send all engine power to the rear.
It's more than a foot longer than an Audi A3, 10 inches longer than a BMW 135is, and close in overall exterior dimensions to an Acura ILX. Yet it's lighter than the C250 and some of its smaller competitors, including the 135.
