Jaguar Could Return to Inline-Six Engines
In many ways, the Jaguar XE is the perfect British retort to a sport-sedan market flooded with Germans. It comes with just about everything you would expect from a Jag: a lightweight body, a functional, yet luxurious interior, and some very sexy lines to ogle. The one thing missing, however, is an inline-six under the bonnet.
If the U.S. owns the V8, you could argue that the UK owns the inline-six. It’s an engine configuration that can be found in some of the UK’s greatest sports cars; a tradition that continued right up until the 1990s, when an increase in crash standards made the shorter V design more desirable. Now, however, it appears as though Jaguar may return to its six-cylinder roots.
The rumors come amid a full reveal of the XE’s technical specs last month. While this newest model comes equipped with a supercharged, 3.0-liter V-6, the possibility for a future inline configuration was neither confirmed nor denied by chief engineer for the Ingenium engine range, Paul Witworth.
“I’m not going to tell you whether we’re going to do a V-6 or an I-6 [inline six],” Witworth told motoring.com.au. “But what I will say is an I-6 has less moving parts for a start and when it comes to fuel economy and emission the less moving parts you’ve got the better you are.”
“Straight-six cylinder gives some challenges for vehicle packaging- it’s more difficult to [achieve good] crash [test results]. But the engine will be inherently more efficient. It’ll be lighter and it’ll be cheaper [to build],” he added.
Mercedes has already made a transition to the inline-six with its new E-Class sedan. If Jaguar was to offer an inline-six in the future, it’s very likely it’ll appear in the upcoming XF, which will feature a new iteration of the Ingenium engine line yet to be revealed.

Why It Matters
When it comes to British motoring, few sounds are as evocative as the inline-six. There’s a harmony to it, a purr that crescendos as the revs build. It’s something that’s lost when the cylinder banks become angled. Chalk it up to vibration caused by the layout of the V-engine, a problem that the inline-six simply doesn’t have. This smoothness makes the inline-six extremely refined when it comes to power delivery, with far less thrash than a typical V or flat design. It’s something that made British sports cars unique, and we’d love to see it return.
