Overview

SIN Cars is a specialist sports-car manufacturer founded by Bulgarian engineer and racing driver Rosen Daskalov. The business began in 2012 under the name SIN Cars Limited in Great Britain, reflecting Daskalov's engineering and motorsport background and the company's initial international orientation. It subsequently developed into a manufacturer associated with both Bulgaria and Germany, moving its headquarters first to Munich and later to Ruse, Bulgaria. The company's best-known road product is the SIN R1, a road-legal sports car that entered production in 2015. The R1 uses a 6.2-litre V8 engine and, according to the available reference material, produces 444 bhp and accelerates from 0 to 62 mph in approximately 3.5 seconds. The model positioned SIN Cars in the low-volume, performance-focused segment rather than the mass-market automobile industry. Its portfolio also includes the SIN R1 GT4 racing specification, the modular SIN S1, and the SIN L City range, comprising a small city-oriented vehicle and a van variant. Motorsport has been central to SIN Cars' identity and product development. The company entered the GT4 European Series for the 2015 season with the SIN R1 GT4. Sofia Car Motorsport competed with the car and finished eighth in the final standings. In 2016, Racers Edge Motorsports used a SIN R1 GT4-specification car in the Pirelli World Challenge. These programs gave the company a platform to demonstrate the racing derivative of its road-car technology and reinforced its positioning as a performance and engineering-led manufacturer. In November 2018, SIN Cars announced plans to finance an expansion into electric vehicles. The proposed direction focused on a multifunctional compact urban vehicle intended for uses such as courier deliveries, taxi services, and general transportation. The stated rationale was that European cities were expected to impose increasing restrictions on diesel vehicles and would require cleaner forms of urban mobility. This plan broadened the company's stated ambitions beyond conventional sports cars, although the available reference material does not establish that a specific electric model reached series production. SIN Cars therefore combines three strands: low-volume road sports cars, customer or professional motorsport, and proposed urban electric mobility. Its history is comparatively short and the available public material provides limited information about ownership, financial performance, production volumes, distribution, and current executive management. Those areas should be verified against current company disclosures before being treated as established facts.

History

SIN Cars was established in 2012 as SIN Cars Limited by Rosen Daskalov, a Bulgarian engineer and racing driver. The company was founded in Great Britain, but its later development connected it with both Germany and Bulgaria. Its headquarters moved to Munich, Germany, before ultimately being relocated to Ruse, Bulgaria. This geographical evolution reflected the company's cross-border character while placing its later manufacturing identity more firmly in Bulgaria. The company entered the road-car market with the SIN R1. Production of the road-legal sports car began in 2015. The R1 was specified with a 6.2-litre V8 engine producing 444 bhp and a claimed 0-to-62-mph time of 3.5 seconds. It represented SIN Cars' core proposition: a low-volume performance automobile developed by a company with direct links to engineering and racing rather than a conventional high-volume manufacturer. Motorsport provided a second route for the brand's development and visibility. SIN Cars entered the GT4 European Series in 2015 using the SIN R1 GT4. Sofia Car Motorsport competed with the car and ended the season eighth in the final standings. The following year, Racers Edge Motorsports used a SIN R1 GT4-specification vehicle in the Pirelli World Challenge. These appearances connected the road-going R1 with a competition program and demonstrated the company's effort to establish a presence in organized GT racing. The model family described in available reference material extends beyond the R1. It includes the SIN R1 GT4 racing car, the modular SIN S1, and the SIN L City line, consisting of a city-oriented vehicle and a van. The available material does not provide complete production dates, technical specifications, pricing, sales figures, or distribution information for every model, so the relative commercial importance of these products cannot be determined reliably. In November 2018, SIN Cars announced an intention to finance expansion into electric vehicles. The proposed product was a multifunctional small city vehicle designed for practical urban roles such as courier delivery, taxi operation, and transportation. The company linked the proposal to expected restrictions on diesel vehicles in European city centers and to demand for cleaner urban transport. The announcement marked a strategic broadening from specialist sports cars and racing cars toward utility-focused electric mobility. The available reference does not confirm the subsequent production or market launch of a specific electric vehicle. SIN Cars' documented history consequently consists of a short period of company formation, relocation, road-car production, motorsport participation, and an announced electric-mobility strategy. Publicly available material is limited regarding present ownership, management beyond the founder, manufacturing scale, commercial performance, current product availability, and geographic sales markets.
