Mercedes A-Class refresh includes crown-stealing 381-hp A45 AMG

We're sure the 362-horsepower Audi RS3 Sportback enjoyed its brief reign at the top of the hot-hatch horsepower charts. But now, Mercedes-Benz updated the A-Class so that it reclaims the throne, castle, and jewels: the Mercedes-AMG A45 4Matic comes with 381 hp from its turbocharged 2.0-liter four-cylinder, a significant bump of 36 hp, and 350 pound-feet of torque, an increase of 18 lb-ft. The seven-speed dual-clutch gearbox gets shorter ratios from third to seventh gears, so its 0-62 mile-per-hour time has dropped from 4.6 seconds to 4.2 seconds. The A45 gets a Dynamic Select system – driving modes controlled by a rotary knob – that comes standard with four modes: Comfort, Sport, Sport +, and Individual. Opt for the AMG Dynamic Plus package and you get a mechanical locking differential on the front axle, the two-stage AMG Ride Control sport suspension with adaptive damping, and a Race mode. Outside, additional aero aids are applied to the nipped-and-tucked bodywork changes made to the entire A-Class range. The spoiler lip under the new front bumper, rear roof spoiler, and rear diffuser, create more downforce than before. Inside, the new flat-bottomed steering wheel is joined by sport seats that allow bolster depth adjustment. And for all those upgrades, fuel economy has stayed the same at 6.9 liters per 100 kilometers on the European cycle. Even away from that tectonic shift, Mercedes made plenty of changes to the A-Class landscape. The new front bumper is said to be "more arrow-shaped," in homage to the the Concept A-Class from 2011, that stretches its look horizontally. LED headlights, standard on the A45, are optional here, and are paired with interior ambiance lighting. In back we get new taillights and some angular exhaust finishers laid into a diffuser-like insert, an alteration we're seeing across the entire Mercedes line-up. Inside, you'll find a redesigned instrument cluster with new graphics, higher-quality finishes on the switchgear, seats with adjustable bolster length, and new color options. Four driving modes are incorporated into the Dynamic Select system: Comfort, Sport, Eco, and Individual. The Eco mode has been tweaked to return even more fuel savings. This Mercedes is also the first to incorporate Apple CarPlay and MirrorLink for the non-iOs smartphoners.

Daimler and Geely collaborate to develop 'a highly efficient modular engine'

BERLIN — German car maker Daimler said on Tuesday it will cooperate with China's Geely to build next-generation combustion engines for use in hybrid vehicles. Efforts to share development costs come as the growth potential for combustion engines faces the twin threat of the COVID-19 crisis and stricter fuel-efficiency and emission rules. "The companies plan to develop a highly efficient modular engine," a spokesman for Daimler said, adding that it would be used in hybrid drivetrains and manufactured in Europe and China. Geely declined to comment. The modular engine will be used in cars under different marques at Geely and Daimler, a person familiar with the matter said on condition of anonymity as the companies are still in the early stages of developing the engine. News of the alliance was a surprise to Daimler's works council at its factory in Untertuerkheim, which specializes in electric and gasoline powertrain assembly. "We are speechless. There was not even a discussion about potential alternative manufacturing locations," said Michael Haeberle, the works council chief for Untertuerkheim. "We have the ability to build four-cylinder engines in Untertuerkheim, but there were no talks about it." Daimler said German factories will be retooled gradually to add electric drivetrains production. Most of the next-generation combustion engines will be made in China, business daily Handelsblatt reported. The alliance with Geely, which owns a 9.69% stake in Stuttgart-based Daimler, means that parts of Daimler's existing partnership with Renault could be pared back. A Renault source told Reuters that the Daimler-Geely project does not mean an end of cooperation between Daimler and Renault. Citing Daimler sources, Handelsblatt said the Daimler-Geely pact would save the German carmaker a "triple-digit million sum" — implying an amount above 100 million euros ($119 million) and less than 1 billion euros.

SRT Viper dukes it out with Mercedes SLS Black Series in new Head 2 Head

In Episode 36 of Motor Trend's Head 2 Head, now that the Corvette ZR1 is no more, Jonny Lieberman has to look overseas to the Mercedes-Benz SLS AMG Black Series for a challenger with similar philosophy to the SRT Viper: long hood hiding a high-horsepower engine set way back, rear-wheel drive, tiny trunks. That puts the Viper's 8.4-liter V10 with 640 horsepower and 600 pound-feet of torque against the SLS AMG's 6.2-liter V8 with 622 hp and 468 lb-ft.
However, the congruences in philosophy and magnitude of numbers doesn't translate to the driving experiences of the two, which are literally and figuratively on different continents. Lieberman gets a handle on the two of them on Northern California roads, Randy Probst then finds out how, and how quickly, they can lap Laguna Seca.
They both get kudos for being improvements on their original sources, but only one of them can take the win. You can find out by watching the video below.
