Aston Martin Vantage might get a Mercedes inline-six

Aston Martin has turned its eye to the inline six-cylinder engine Mercedes-Benz installs in the CLS 53. The British carmaker uses an AMG-sourced 4.0-liter V8 for the DB11 and the Vantage, which produces 503 horsepower and 505 pound-feet of torque in the latter coupe. Aston Martin hasn't said anything about whether or when it would use the inline-six, nor mentioned a product to slot the engine into. If the six does migrate from Germany to England, the move brings several benefits for Aston Martin, and it would create the first six-pot Aston Martin since the 1999 DB7. The 3.0-liter, AMG-built six-cylinder uses an electric turbocharger to put out 430 hp and 383 lb-ft of torque, and gets help from a 48-volt EQ Boost micro-hybrid system throwing in 21 hp and 184 lb-ft. After driving it at a Mercedes-Benz test track, Aston Martin's chief engineer Matt Becker called the powerplant "very complicated and clever," and said, "it's a very impressive engine" that he could envision serving the brand. The 2019 Vantage engine bay can already fit the company's in-house, 5.2-liter V12, so a straight-six shouldn't be hard to swallow. As for how it would fit into the lineup, there's a chance a six-cylinder Vantage supplants the V8. However, since Becker said his engineering team "would not necessarily play" with the AMG's power curves, that option would probably have to wait until AMG upped the three-liters' output. We'd be surprised if Vantage buyers would accept giving up two cylinders and 73 hp. More likely, a six-cylinder Vantage could give Aston Martin a new entry-level model to undercut the $153,081 Vantage V8, but with plenty of ponies to thrill. A V6 coupe could also help the carmaker's emissions scores, and serve specific markets such as China where engine displacements greater than three liters get hit with heavy taxes. Related Video:

Aston Martin working on an inline-six to replace Mercedes-sourced V8?

There's no straight line to figuring out whether Aston Martin plans a straight-six motor for future products. In March, comments by the automaker's chief engineer for vehicle attributes, Matt Becker, led many to believe the British firm could use the Mercedes-AMG 3.0-liter hybridized inline-six from the new CLS53. A week later, Becker said his comments had been misconstrued, that he "was speaking in more general terms that we might have to one day look at downsizing engines." Autocar just threw a new curve, citing "a source close to the firm" to report that Aston Martin's working on its own straight-six. The English outlet says the deal Aston Martin signed with Mercedes-AMG was a stopgap deal while Aston Martin worked on proprietary engines. The report says the inline-six developed in Gaydon would eventually replace the 4.0-liter twin-turbo V8 currently powering the DB11 and Vantage. If this purported inline-six were augmented with electrification, perhaps developed with help from the electric Rapid E program, it could make more sense of Becker's first, misconstrued comments. At the time, Becker said the Mercedes hybridized engine "could fit with the brand in the future." Taken generally, he could have meant an Aston Martin version of the German engine. The certainty is that there's a six-cylinder coming for larger-volume series production models, yet the reports and denials put competing rumors and powerplants in play. Aston Martin installs a 5.2-liter V12 in the DBS Superleggera, and Autocar suspects an inline-six could be derived from that engine. The automaker already has a six-cylinder in development, though, that being the turbocharged hybrid V6 said to be headed to the Ferrari- and McLaren-fighting Valhalla. Creating two new six-cylinder engines in different formats seems an odd choice for a tiny manufacturer. What about the rumors that say the DBX crossover could get a six-cylinder? In July, when Motoring asked chief creative officer Marek Reichman about it, he said the DBX "could [use a Mercedes-sourced six-cylinder], because that would be a pretty good engine and combination. Potentially." Autocar suggests, however, that the DBX will be first in line for the in-house inline engine. Aston Martin has a storied history with the inline-six, all of them with links to other automakers. The legendary inline-six in the original DB cars of the mid-20th century were originally drawn up by Walter Owen Bentley - yes, that W.O.

Jaguar F-Type squares off against Porsche 911, Aston V8 Vantage with Chris Harris

Chris Harris is back on the job, taking on really really difficult car questions like: Which enormously sexy and good-to-drive, high-performance convertible is the top of the heap? As one of the hottest cars in the luxury space right now, the Jaguar F-Type S is, of course, in on the action. Competition comes in the form of the Aston Martin V8 Vantage Roadster and the Porsche 911 Carrera S Cabriolet. Sun-loving CEOs who despise test-driving need look no further.
Scroll on below for a fully featured (with a running time of more than 20 minutes) comparison video. Harris does his best to entertain - in a typically nitpicky and made-up-British-words fashion - and the moving pictures are lovely to look at. Kick back, pour a pint and get your weekend started off right.
