The MG07, the Taycan, and Why Fast EVs Share a Silhouette

MG's new performance sedan, the MG07, arrived to a familiar reaction: people lined it up next to a Porsche Taycan and a Xiaomi SU7 and started pointing at the roofline. It is a fair thing to notice. It is also the least interesting thing about the car, because the resemblance is not a story about who copied whom. It is a story about physics, and once you see the physics you cannot unsee it on any fast EV.

The Silhouette Is Solved Physics, Not a Signature

Here is the boring engineering answer nobody makes a video about. Fastback rooflines, flush door handles, tapered tails, low noses, and rear-biased greenhouses are not styling signatures anyone owns. They are aerodynamic optima. Below a drag coefficient of roughly 0.22, the wind tunnel starts telling every designer the same thing, and the range spreadsheet enforces the recommendation. An EV that fights its drag number pays for it in kilowatt-hours per hundred kilometres, and that shows up on the window sticker where buyers actually feel it.

Line up the Porsche Taycan, the Xiaomi SU7, the Tesla Model S, and the Mercedes EQS in profile and the outlines converge. They converge because they were all solving the same equation. That is convergent evolution, the same answer arrived at independently by teams with different logos, different budgets, and the same physics and the same regulatory range test. It is not a conspiracy of pens. Sharks and dolphins landed on the same body plan for the same reason, and nobody accuses the dolphin of tracing the shark.

The MG07 sits in exactly this lineage, and MG has more claim to the shape than most. Its parent, SAIC, has been building slippery sedans for years, and the engineering muscle behind a sub-0.22 body is not something you borrow from a press photo. This is a company that can afford its own wind tunnel time.

Where Cars Actually Differentiate Now

If the side profile is settled physics, the real design work has moved to where the physics leaves room: the front fascia, the light signature, the interior architecture, and the proportions. That is where a brand tells you who it is. The Mercedes-AMG GT 4-Door and the Taycan share a silhouette family for exactly the aerodynamic reason above, and nobody mistakes an AMG cabin for a Porsche one. The interesting questions about the MG07 are the same ones you would ask of any new performance sedan: how does the interior feel, where do the proportions land, and what does the car do that the spec sheet cannot show. Those are review-bench questions, and they are the fun part.

It is worth remembering that the studio everyone uses as the reference point is itself in motion. Porsche's design leadership is in the middle of a handover from Michael Mauer to Tobias Sühlmann, which means the "original" everyone measures against is rethinking what it wants to draw next. Design languages are living things. The performance-sedan silhouette is a shared starting point, not a finish line, and the brands that stand out will be the ones that do the most with the details the wind tunnel leaves alone.

What Actually Decides the MG07 in Canada

For Canadian buyers watching from outside the design conversation, the roofline is the least important variable on the page. The operative math is country-of-origin: the January 2026 tariff cut from 100% to 6.1% under a 49,000-unit quota, and the EVAP rebate exclusion for China-built vehicles regardless of price. That is the axis a landed MG07 would have to survive, and it will decide the car's Canadian story long before anyone reaches for a Porsche comparison.

If the MG07's numbers land where MG needs them, its range, its charging curve, its chassis, and its price, the silhouette debate evaporates on contact with the first honest review. Chinese performance EVs have spent the last three years proving they can build the hardware. The MG07 is the next data point, and it deserves to be judged on what it does, not on which car it reminds you of at a glance.
