Mercedes-AMG considering turbo fours, hybrid sixes for future performance sedans

Think of the letters AMG and you'll probably end up picturing a performance sedan with a big V8. Such has become, after all, the Mercedes turning division's calling card. But with the introduction of its 2.0-liter turbo four, AMG is working at turning that notion on its head.
The highly potent engine produces 355 horsepower and is presently installed in the A45 AMG hatchback, CLA45 AMG sedan and GLA45 AMG crossover, giving Benz's smallest family a full range of performance models. But that might not be the full extent of the high-strung four-pot's use.
Speaking with AMG boss Tobias Moers, Britain's What Car? magazine reports that Affalterbach is considering slotting the same engine into larger models, particularly performance sedans like the C-Class. As we recently reported, Mercedes is already preparing to up the power from the turbo V6 in the C400 to slot a C450 Sport in below the C63 AMG. The C450 is expected to offer around 367 horsepower where the CLA45 AMG et al pack 355, but the lighter weight of the four-cylinder engine would likely offset the truancy of those extra dozen horses. Of course such a prospect would be much further down the pipeline than the C450 Sport which is expected to arrive much sooner.

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.

Kimi Raikkonen fastest in first Belgian Grand Prix practice

SPA-FRANCORCHAMPS, Belgium — Ferrari's Kimi Raikkonen lapped fastest in first practice for the Belgian Grand Prix on Friday but Mercedes, and title contender Lewis Hamilton, still looked every bit the team to beat. A four-time winner at Spa, and with a contract extension for 2018 announced earlier in the week, Raikkonen lapped the longest track on the calendar with a best time of 1 minute 45.502 seconds. The 37-year-old Finn's time was set on the quickest ultra-soft tires, however, while Hamilton — preparing for his 200th race start — was second-fastest and only 0.053 slower on the soft compound. Hamilton was 0.092 faster than Ferrari's world championship leader Sebastian Vettel, with the German third on the timesheets and also setting his time on the quickest but least durable tire. Vettel leads Hamilton by 14 points with nine races remaining. Red Bull's Dutch teenager Max Verstappen, Belgian-born and attracting a huge traveling support of orange-capped fans, was fourth fastest with Australian team mate Daniel Ricciardo fifth. Hamilton's teammate Valtteri Bottas, who bumped into the tire barrier after going off across the gravel and damaged his front wing, was sixth fastest. The session was halted after 15 minutes when Brazilian Felipe Massa, who missed the previous race in Hungary after feeling dizzy in practice, crashed heavily into the tire barrier at turn seven out of Les Combes. He was taken to the medical center for checks, before returning to the pitlane, with his team facing a long job rebuilding the car. The session resumed after a 10 minute stoppage. Williams said the chassis would have to be changed and the team still hoped to get the car back out on track for some of the day's second session, even if that looked like being optimistic. Fernando Alonso suffered a lack of power in his McLaren, but still ended up 13th fastest. Belgian team mate Stoffel Vandoorne, who will start his home race last on Sunday thanks to a 35 place penalty due to a power unit change, was 10th.
