Mercedes-AMG C63 a step closer to dropping four-cylinder PHEV
Latest report confirms previous speculation of the C63 reverting to six-cylinders, also with a plug-in hybrid setup, instead of reviving the V8.

With rumours of its move away from four-cylinders continuing to mount, a senior Mercedes-AMG employee has let slip that the controversial plug-in hybrid (PHEV) powertrain in the C63 will indeed be phased-out based on poor reception and slumping sales.
No, yes?
First mentioned in 2023 following a report from US publication Car and Driver that the 2.0-litre based unit has received significant backlash despite being powerful than the 4.0-litre bi-turbo V8 it replaced, an AMG figure head stated that adapting the V8 for Euro 7 emissions regulations had already taken place in response to dealers struggling to shift units dramatic prices cuts.

According to the most recent report by carscoops.com, Mercedes-Benz dealers in the United Kingdom have offered discounts of up to £9 500 (R233 386) on the C63, bringing its price tag to £90 095 (R2 213 363) or £17 525 (R430 536) less than the sticker price of the BMW M3 Competition.
'We could have explained it better'
Similarly, discounts in the States have also been enforced, with AMG CEO, Michael Schiebe, admitting to MotorTrend last month that it 'could have better explained' the system before putting it into the C63.
'There are pure V8 fans, and it's hard to convince them of this four-cylinder hybrid technology. It's my job to do a constant review of our portfolio. I'm pretty confident that we will fulfil our customers' dreams in the next two to three years,' he said.

Despite Mercedes-AMG debunking the hybrid's withdrawal in a response to Germany's Auto Motor und Sport days after the Car and Driver statement, an unnamed executive has admitted to Britain's Autocar that the setup has 'failed to resonate' with buyers.
'Technically, the four-cylinder is one of the most advanced drivetrains available in a production car. It's also right up there on performance. But despite this, it failed to resonate with our traditional customers. We've recognised that,' the source told the publication.
In spite of its combined outputs of 500kW/1 020Nm, 125kW/270Nm more than the V8-engined C63, the newcomer' 2 165 kg kerb mass has been cited as another reason for its slump in sales, with recent evaluations in Europe and the States also criticising the battery pack getting hot at over 200 km/h.
Return of six
In confirmation with the most recent Autocar report in April, the unnamed source said the plug-in hybrid 2.0-litre will give away to a six-cylinder in the reported form of a 3.0-litre plug-in hybrid modelled on the mild-hybrid configuration that powers the AMG CLE 53.
Seemingly not earmarked for a return is the 4.0-litre V8, which will produce a reported 478kW/880Nm with mild-hybrid assistance in the forthcoming AMG CLE 63.
While no official word from Mercedes-AMG has yet been made confirming the move to back six-cylinders for its flagship C-Class since the supercharged C32 AMG made from 2000 to 2004, expect possible clearer details to emerge throughout the rest of the year.

Norris bounces back as McLaren take 1-2 in Austrian practice
Lando Norris bounced back from his Canadian catastrophe with his customary smile on Friday after topping the times ahead of team-mate and championship leader Oscar Piastri as McLaren reeled off a solid 1-2 in practice at the Austrian Grand Prix. As the paddock digested news that Mercedes had held talks about possibly signing Max Verstappen from Red Bull alongside George Russell in 2026 Norris clocked a best lap in one minute and 4.580 seconds to beat Piastri by 0.157 seconds. Four-time champion Max Verstappen was third fastest for Red Bull, adrift by 0.318 seconds. For Norris, who sat out the first session at the Red Bull Ring, it was a relief to move on from his collision with team-mate Piastri in Montreal where he retired pointless, admitting he had "made a fool of myself". "I didn't mind sitting on the pit wall," he said, with a grin, referring to missing the morning session. "I actually felt a lot more relaxed there than in the car, especially here. "I've always enjoyed this track. The car felt good right from the start. Alex (Dunne, reserve driver) gave solid feedback this morning after FP1 and was on pace straight away, which was encouraging to see." Norris added that he was pleased with the development of the car with McLaren's latest upgrades. "They definitely moved the car in the right direction for FP2," he said. "Now, we just need to figure out if we want more of that tomorrow, less, or somewhere in between. "So, it's a good step forward, but hopefully there's still a bit more to come." - 'Max is still close' - AFP | Joe Klamar McLaren came to the Styrian Alps with three performance-based updates including aerodynamic revisions of the front and rear of the car and suspension. Piastri, who leads Norris by 22 points in the title race, said he was satisfied with his first day in the car. "It looked pretty good," he said. "Max is still close, so I think he'll definitely be a threat this weekend, but the car's feeling good. I think the pace is quite good, so a positive first day." He added that both he and Norris had "all the parts that we think will make the car faster" on their cars. Verstappen, who took his time to improve through the sessions, said: "We didn't have any big issues. "We lack a bit of pace and had too much understeer, both on the short and the long run. So that is something we have to try to get rid of." Lance Stroll was fourth for Aston Martin ahead of Ferrari's Charles Leclerc, George Russell of Mercedes, who won last year and two weeks ago in Canada, and Yuki Tsunoda in the second Red Bull. Gabriel Bortoleto was eighth for Sauber ahead of two-time champion Fernando Alonso of Aston Martin and seven-time champion Lewis Hamilton, struggling in his updated Ferrari. Norris added: "We've shown a bit more pace than some others, so I certainly think they're going to catch up. Max is not far behind and they normally improve a lot on Saturday. "So I expect a good day tomorrow (Saturday) and I'm sure we'll improve on some things, but it's not as easy as maybe it looked. "I think it's still going to be tight tomorrow — it always is. There's no reason for it not to be, but we'll work hard to make it as big of a gap as possible."

Hamilton given formal warning as difficult Ferrari start continues
Lewis Hamilton's difficult start to life at Ferrari continued on Friday as he was handed a warning by the race stewards after winding up 10th in second practice for the Austrian Grand Prix. The seven-time champion was alleged to have impeded his successor at Mercedes, Italian teenage rookie Kimi Antonelli, at turn four of the fast and technical Red Bull Ring circuit in the Styrian Alps. Hamilton apologised immediately and explained that he had not seen Antonelli approaching behind him as he descended over the crest of a hill on a slow lap and drifted into the racing line. Hamilton raised his hand to signal his apology to Antonelli as he passed him. After speaking to Hamilton, the stewards decided to give the Briton a formal warning -- the usual sanction for such a misdemeanour in practice. It is the third time this season that Hamilton has been warned. "The driver of car 44 (Hamilton), although constantly checking his mirrors after being informed by the team about car 12 (Antonelli) closing in, slowly moved on to the racing line on the approach to turn four and thereby unnecessarily impeded car 12 which had to take evasive action," said the stewards in a statement. Hamilton was given a three-place grid drop at the Monaco Grand Prix where he impeded four-time champion Max Verstappen in qualifying when his race engineer Riccardo Adami wrongly informed him that the Dutchman was not on a flying lap. Hamilton struggled with gearbox problems on Friday as he evaluated a new floor design on his Ferrari car.

Wolff dismisses speculation of Verstappen joining Mercedes in 2026
George Russell is more likely to stay with Mercedes next year than Max Verstappen is to join, the Formula One team's boss Toto Wolff said on Friday while confirming his interest for the future. Russell indicated on Thursday that Mercedes were talking to Verstappen about a move from Red Bull and suggested that was why an extension to his own contract beyond this season was taking time, lthough he was confident for the future. 'There is no delay in George's contract negotiations,' Wolff told Sky Sports television at the Austrian Grand Prix, where Russell was fastest in first practice. 'It's pretty clear since a long time what our timings were and are, we've known each other for such a long time and so there is no such thing as a delay.' Wolff said it was a question of trying to understand what time framework Verstappen, a four-time world champion who is contracted to Red Bull until 2028, was operating under and what his plans were. 'And that could be long into the future,' he added. 'But that has no effect on us putting a signature on George's contract.' Russell said on Thursday it was normal Mercedes would want to talk to Verstappen. Asked if Russell, whose teammate is 18-year-old Italian rookie Kimi Antonelli, was more likely to be in the Mercedes than Verstappen next year, Wolff replied: 'Yes.' 'What we are trying to do in the team is to be transparent ... you can either choose to hold things under wraps or like we have done in the past 10-12 years is put it out there and say 'this is the situation',' said Wolff. 'There is no such thing as saying 'we are going to sign Max'. This is so far away that it is not realistic. With George, we talk about everything.' Speaking to reporters earlier, Wolff said everything was normal and going to plan with Russell's contract talks. He also did not rule out pairing Russell and Verstappen in future, despite their recent public feuding and on track clashes. 'I can imagine every line-up. I had Rosberg and Hamilton fighting for a world championship, so everything else afterwards is easy,' said the Austrian. 'There's pros and cons of having two drivers fighting each other hard. 'We've seen examples where that functioned and other examples where it didn't.'
