After recently being acquired by China's Geely, which now has a 51 percent stake in the company, Lotus has more financial stability to do what it does best: build ultra-lightweight sports cars that are delightful to drive. Over the past week, the automaker's social media channels have been buzzing with mysterious images teasing a surprise new car reveal, showing off its beefy brakes, evolved aerodynamics and rear air ducts made of carbon fiber. But what could it be?

Currently, Lotus offers three models: the Elise, Exige and Evora, and it's already been confirmed that we won't be seeing any new models outside of this core line-up. Before you get too excited that we're looking at the next-gen Elise, that seems unlikely since it won't be ready until 2020. Chances are the cryptic images are showing a new Evora derivative, which should please US fans as it's the only car in the Lotus line-up currently sold stateside. The 19-inch alloys look like they belong to an Evora, as does the rear bumper. There's a strong possibility we're looking at the new Evora Roadster, since Lotus has already confirmed it will be revealed this year. A summer reveal would also make sense.

Given the emphasis on increased power, upgraded brakes and "aerodynamically evolved" bodywork, the Roadster could be based on the Evora 410, which is more powerful and lighter than the Evora 400 coupe. If true, the Roadster variant will likely retain the hardtop's 3.5-liter supercharged V6 engine with 410 horsepower and 310 lb-ft of torque. While the fixed-roof Evora 410 has a dry weight of just 1,280 kilograms, keep in mind the Roadster will probably be heavier which could hamper its performance. Having said that, it looks like the bodywork has been coated with extra carbon fiber to compensate. The final video teaser is the most intriguing.

Confirming that a reveal is imminent on July 20, the video shows what looks like a track-focused car with similar proportions to the Evora hidden under the covers. On closer inspection, it appears to have the same roof grooves as the hardtop Evora 410, so it may not be a roadster after all. Whatever the new mystery Lotus turns out to be, all will be revealed tomorrow. So stay tuned.
