Two California automotive engineers are drawing attention by developing a high-performance roadster sports car that weighs only 600 kilograms. The body was conceived by the legendary roadster, Miata Mazda.






The powertrain is adapted by tuning a 1.65L engine on the BMW Motorcycle K1600R to match the weight reduction. Surprisingly, the price is as high as $500,000 (about 800 million won).




Spencer Beckman and Kyle Kruger of the production company of "Shoreline Bespoke" are the main characters who developed such an amazing car, according to CasCoups.






Founded in 2021, the company is developing a retro-style lightweight two-seater sports car. The two unveiled a rolling chassis that modified their vehicle last year, just as Lamborghini produced Miura in 1965.









As we enter the era of electricity these days, new cars are getting bigger, heavier, and more complex, and Shoreline expects the 'LM Coupe', which is powerful in lightweight, to be differentiated.






LM Coupe's distinction begins with several classic racing cars, particularly the Porsche 906 inspired design of the 1960s. Combining timeless elegance and modern technology, the coupe brings new life away from the sports car design of big makers.

The new sports car weighs just half the weight of the Mazda lightweight roadster "Miata." It's only a little over 600kg. It is equipped with a BMW series six-cylinder engine.






The core of the LM coupe is a manually manufactured tubular steel space frame. The vehicle was fitted with an adjustable double wishbone suspension, AP racing brakes, and a customized steering system at four corners.

All of these factors combined to create a lightweight car weighing only 635 kg. The lighter the weight of a lightweight sports car, the better the performance. It weighs almost half of the fourth-generation ND Miata (basic weight of 1073.2 kg) of Mazda, which appeared in 2025 and is currently on sale.






It seems natural that Shoreline chose a small but thrilling engine while making the LM coupe as light as possible. Behind the seat, BMW will be equipped with a 1.65-liter natural inhaler series six-cylinder engine, which is estimated to be based on the K1600 motorcycle engine.






This engine is upgraded by tuner Ed Pink, which exerts up to 250 horsepower.It not only boasts powerful power, but also rotates up to 10,000 rpm. Shoreline applied a sequential gearbox with clutch pedals without using a conventional H-pattern manual transmission.

The interior is inspired by classic racing prototypes. It features an adjustable pedal box and a carbon fiber bucket seat that is secured in a fixed position using a steering wheel. There is no infotainment screen, only a magnetic cell phone holder.






Shoreline will introduce LM coupe at 'Monterreyka Week' in August this year. It is priced at around $500,000 (about 700 million won), and it will start delivering customers from the end of 2026.
