Weekly Recap: New bosses try to jump-start Cadillac and Lincoln

Both of America's domestic luxury brands seem to be stuck in neutral.
It's ironic that Cadillac and Lincoln got new bosses within days of each other this month. It's also a commentary on the fact both of America's domestic luxury brands seem to be stuck in neutral.

2020 Aston Martin Vantage AMR First Drive Review | It has a manual!

NURBURG, Germany — The new Aston Martin Vantage AMR has a manual transmission. In the precision-engineered, sequential dual-clutch automated hell-scape in which we now dwell, that might be enough copy for a full review. But driving this boisterous menace around the perfect, sweeping, foothilly roads around Germany's Nurburgring (but not on the ‘Ring itself), I discovered that the seven-speed stick shift makes the Vantage approximately 77% more engaging. For this, we have Aston Martin CEO Andy Palmer to thank. “Andy committed to always having a manual in the lineup,” said transmission engineer James Owen, at the Aston Martin Racing (AMR) Performance Center at the edge of the ‘Ring, when I asked, insolently, why this car exists. “And as the sports derivative of our sportiest, most focused sports car, Vantage, itÂ’s right for the lineup.” A bit more about that transmission, because it should be dwelled upon: It is built by famed Italian manufacturer Dana Graziano, which has been building transmissions for the likes of Ferrari, Maserati and Alfa Romeo since the middle of the past century. It has a dogleg high-ratio first gear that requires some increased load to knock into. It rev-matches on downshifts, and also allows no-lift upshifts, so you can keep the pedal floored between gears to minimize transitions. ItÂ’s air cooled, for less weight. And it has a Launch Control feature that works like this: clutch down, find first, stomp on the gas, wait for the little light to appear on the dash, clutch out progressively but quickly. Glory. It was, in fact, surprising just how much the gearbox changed my relationship with the Vantage, a car I already liked. The AMR doesnÂ’t add any power, the Mercedes-sourced 4.0-liter turbo V8 still sits at 503 hp. But the torque figures are down significantly, from the 505 pound-feet available in the automatic to 461 with the manual. Remember, this is the first time a manual has been paired with this engine, be it by Aston Martin or Mercedes-AMG. Despite losing 200 pounds from the Vantage's curb weight – through the use of the lighter transmission, forged wheels, carbon ceramic brakes, carbon fiber body and trim bits, and the switch from an electronic differential to a limited-slip one – itÂ’s nearly a half-second slower from 0-60 than the base Vantage (3.9 seconds vs 3.5).

Aston Martin DB11 V8 loses four cylinders but none of its grace

We love the Aston Martin DB11. Few vehicles combine speed, luxury, and comfort as well as that beautiful British coupe. That said, it's not the most efficient or affordable GT in the world, but Aston Martin is planning to change that. Starting this year, the company will offer the DB11 a twin-turbocharged V8 sourced from the mad Germans at Mercedes-AMG. We've known about the engine partnership for a while now, though we assumed the first Aston Martin to use a Mercedes-AMG V8 would be the next-generation V8 Vantage. At first, sticking a V8 under the hood might seem like an odd choice, but the DB series only recently started using V12s. Historically, the car has packed powerful inline-six engines. Offering two engines will allow the company to sell a lower-cost model and presumably boost sales. That means changes are strictly mechanical in nature. The engine is the now-common 4.0-liter twin-turbocharged Mercedes-AMG V8. Output is 503 horsepower and 498 pound-feet of torque. That's down 97 horsepower and 18 pound-feet of torque from the 5.2-liter V12. In the Mercedes-AMG C63 S, the 4.0-liter V8 makes equal horsepower and 18 more pound-feet of torque. Aston Martin says that the partnership with Mercedes-AMG allows the company to tailor the engine for Aston Martins. This means a new ECU with new engine and throttle mapping. Losing four cylinders changes the character of the car a bit. The DB11 V8 is a not-insubstantial 254 pounds lighter than the V12. Since most of the weight savings comes from behind the front wheels, Aston Martin says the V8 model is more agile than the V12 model. Engineers have adjusted the suspension bushing, geometry, anti-roll bars, springs, dampers, and stability control to account for the weight savings. The DB11 V8's diet helps offset the lower power output. As such, the 4.0-second 0-62 sprint is just 0.1 seconds off the V12. Top speed is down 13 mph to a still extralegal speed of 187 mph. We don't have fuel economy ratings for the US, but expect an improvement from the V12's current rating. The V8 will be available with all of the same equipment and trims as the V12, with just a few visual changes to distinguish the two models. The V8 gets unique wheels, darker headlight surroundings, and just two vents on the hood, available in either black or titanium. The DB11 V8 goes on sale in the US later this year. At $198,995, it undercuts the V12 model by $17,500.
