Overview
Carbon Motors Corporation was an American automotive company established in 2003 to design and manufacture vehicles specifically for police and other law-enforcement users. Rather than adapting a conventional passenger car after production, the company sought to integrate police equipment, prisoner-transport features, security systems, and long-life commercial-vehicle engineering into the vehicle at the factory. Its principal project was the Carbon E7, a purpose-built police sedan that attracted attention because it was intended exclusively for official law-enforcement use. The company was founded in Los Angeles by William Santana Li, a former Ford executive, and Stacy Dean Stephens, a former police officer. Their concept was based on the idea that police departments were spending substantial sums converting ordinary sedans into patrol cars and replacing them relatively frequently. Carbon Motors proposed a vehicle designed around the daily requirements of officers, including wearing a duty belt, extended idling, transporting prisoners, storing weapons and equipment, and operating in severe weather. The company also promoted a projected service life of approximately 250,000 miles, substantially longer than the typical patrol-car life it cited. Carbon Motors moved its operations to Atlanta in 2006 while it pursued investment and developed the E7. In July 2009, it relocated its headquarters to Connersville, Indiana, where it planned to convert a former Visteon manufacturing facility and invest approximately $350 million in the site. The company’s manufacturing strategy depended on reaching production scale and securing financing, supplier arrangements, and government or agency customers. In March 2010, it announced an agreement with BMW for the supply of 240,000 six-cylinder diesel engines, supporting the planned use of a BMW turbo-diesel powertrain in the E7. The E7 prototype was publicly presented during the 2008 “Pure Justice” tour. Carbon Motors described it as the first vehicle designed from the ground up specifically for police work. Planned equipment included integrated emergency lighting and sirens, surveillance and recording systems, automatic license-plate recognition, forward-looking infrared capability, weapon storage, ballistic protection options, a prisoner compartment, a push bumper, and a cabin layout intended to accommodate officers wearing equipment. The proposed rear-wheel-drive vehicle was also promoted with high performance, a six-speed automatic transmission, and a governed top speed of 155 miles per hour. These specifications and features remained plans for a vehicle that never entered series production. Carbon Motors also developed the TX7, a much larger truck-based multi-mission vehicle intended for prisoner transport and personnel movement. The design was described as seating ten people and using a turbo-diesel V8 with a six-speed automatic transmission. Only one prototype was produced, and the vehicle did not reach commercial production. The company’s financial position became increasingly dependent on obtaining outside funding. In 2012, the United States Department of Energy rejected Carbon Motors’ application for a $310 million loan under the Advanced Technology Vehicles Manufacturing Loan Program. Energy Secretary Steven Chu said that the department had to assess the likelihood of repayment and the financial viability of the applicant. Carbon Motors criticized the decision and argued that political considerations surrounding the 2012 election had influenced the outcome; Chu later rejected that characterization in testimony before the Senate. Without the requested loan and with the production program unable to proceed, Carbon Motors began removing equipment from its Connersville facility in early March 2013. The plant lease expired on March 31, and the company’s website and YouTube channel disappeared around the same period. By April 2013, Carbon Motors had effectively ceased operations. In May 2013, three former executives sued the company over unpaid deferred wages. Carbon Motors therefore remains primarily remembered for its ambitious E7 concept, its attempt to establish a dedicated American police-vehicle manufacturer, and its failure to transition from prototype development to production.
History
Carbon Motors Corporation was founded in 2003 in Los Angeles by William Santana Li and Stacy Dean Stephens. Li brought experience from the automotive industry, including work at Ford, while Stephens had a law-enforcement background. The founders pursued a specialized business model: instead of selling a civilian automobile later modified for police service, Carbon Motors would engineer the vehicle around the operational needs of police agencies from the beginning. The company’s central project was the E7. Carbon Motors intended the E7 to be sold only to law-enforcement agencies and to remain within that professional fleet system throughout its useful life. The proposed vehicle incorporated features that departments commonly added after purchasing conventional patrol cars, including emergency lighting, sirens, communications and surveillance equipment, weapon storage, protective panels, prisoner restraints, and specialized interior partitions. The front seats were designed around officers wearing duty belts, while the rear compartment was intended for restrained occupants and could be cleaned more easily than a conventional passenger cabin. Carbon Motors moved to Atlanta in 2006 as it developed the product and sought investors. The E7 prototype was shown publicly during the 2008 Pure Justice tour, generating attention for its unusual mission-specific design. In July 2009, the company moved its headquarters to Connersville, Indiana. It proposed investing $350 million to convert a former Visteon facility and use it as the center of its manufacturing operation. The planned Indiana project was important both to the company’s production ambitions and to the local economic-development effort. In March 2010, Carbon Motors signed an agreement with BMW for 240,000 six-cylinder diesel engines. The E7 was planned as a rear-wheel-drive vehicle with a six-speed automatic transmission and a BMW turbo-diesel engine. Carbon Motors promoted a projected 0-to-60-miles-per-hour time of 6.5 seconds and a governed top speed of 155 miles per hour. It also claimed that the vehicle could be engineered for a service life of about 250,000 miles. Other proposed features included ballistic protection, automatic license-plate recognition, 360-degree exterior video, interior monitoring, night-vision-compatible lighting, forward-looking infrared equipment, integrated push-bumper and pursuit-intervention capability, and systems for long periods of idling. The company also proposed the TX7 Multi-Mission Vehicle. The TX7 was substantially larger than the E7 and was intended for prisoner transport and personnel movement. It was described as a truck-based vehicle approximately 6.9 metres long, 2.5 metres wide, and 3 metres tall, with seating for ten people and a turbo-diesel V8. Only one prototype was made, and the planned vehicle did not become a production product. Carbon Motors’ progress depended on securing substantial financing. In 2010 and 2011, the company worked with the U.S. Department of Energy concerning a $310 million loan request under the Advanced Technology Vehicles Manufacturing Loan Program. On March 7, 2012, the DOE rejected the request. Energy Secretary Steven Chu said that the department had to protect taxpayers and determine whether the applicant had a reasonable chance of repayment. Carbon Motors disputed the explanation and suggested that the decision was politically influenced. At a Senate hearing on March 13, Chu stated that politics was not a factor and that the decision concerned the company’s finances and the viability of the loan. The failure to obtain the loan left Carbon Motors without the financing needed to complete its factory and begin volume production. In early March 2013, equipment was removed from the Connersville plant. The facility lease expired on March 31, and the company’s website and YouTube channel were taken offline around the same time. By April 2013, the business had effectively closed. On May 22, 2013, three former executives brought a lawsuit concerning unpaid deferred compensation. Carbon Motors never produced the E7 or TX7 as commercial vehicles, although the E7 concept later appeared in the 2010 video game Need for Speed: Hot Pursuit. It was omitted from the 2020 remastered edition, consistent with the company’s defunct status and the vehicle’s failure to enter production.
