The R143 is a standard gauge New York City Subway B Division new technology (NTT) car built by Kawasaki in 2001-2003. The cars are mainly used on the BMT Canarsie Line (L train), but have been used on other BMT Eastern Division routes as well over their history. The New York City Transit Authority owns 212 R143 cars, numbered 8101 to 8312, and built for an average cost of about $1.5 million per car.
Kawasaki Rail Car, Inc. was awarded a $190 million contract for 100 new B Division cars in late December 1998, with an option for 112 more cars. The new design was based on the A Division's R142A, which Kawasaki also built, and incorporated many features from the R110A and R110B prototypes. Delivery began in late 2001, and a 30-day test with one train of eight cars (8101-8108) began on December 4, 2001. According to Kawasaki, the test was "extremely successful".
R143s began running on the BMT Canarsie Line (L services) on February 12, 2002, and all 212 cars were delivered to the subway by March 2003. In addition to running on the L, where the R143s displaced the R40/R40As and most of the R42s, they also displaced the R42s on the M weekend shuttle service on the BMT Myrtle Avenue Line. The R143s on the M were replaced by R160As in February 2008. One Person Train Operation was tested on the L during mid-2005.
Eight R143s numbered 8205-8212 were originally delivered with experimental Siemens traction motors to test the traction motors that would be later found in some of the R160B cars (numbers 8843-9102). These cars were eventually refitted with the Bombardier traction motors found on all other R143s.
On June 21, 2006, an eight-car R143 train overshot the bumper at the end of the tracks in the Canarsie Yard after the operator suffered a seizure. Lead car 8277 suffered significant damage and has been stripped of damaged parts for repair. It was sent to the Kawasaki plant in Yonkers while the rest of the set (8278-8280) is at the 207th Street Yard. However, 8277 has been worked on for the past 5 years at the 207th Street and Coney Island Repair Shops and the repair work continues to be done. 8278 also suffered a bit of body damage but was repaired sometime between 2009-2011 and coupled back up with 8279-8280.  
Differences between the R143 and R160 cars
The R143s are almost identical to the R160s. However, there are differences between the two car models:
- The R143s have standard plastic card route "strip maps", with 63 LEDs in the map, as well as LED advertisements, while R160s have the FIND system, with 15 "next stop" slots, and Arts for Transit cards, similar to the R142s and R188s.
- The American flag on the ends of the A-unit cars is placed above the MTA New York City Subway logo on the R160s, but below it on the R143s.
- The R143s have Bombardier traction motors while R160s have Alstom and Siemens traction motors.
- The R143s have single storm doors at the blind ends, while the R160s have double storm doors at the blind ends.
- The taillights on the R143s use incandescent bulbs with reflectors while the R160 taillights use LEDs with their characteristic dot-matrix look.
- The rim around the interior LED lights are black on the R160s and white on the R143s.
- The LED side signs are a smaller font on R143s than they are on R160s.
- The propulsion sound on the R143 can be described as a rolling sound similar to R142As and R188s,as the R160s have a stepping propulsion sound like the R142s.

- R160 (New York City Subway car) - a similar car built by Alstom and Kawasaki Railcar (some Alstom cars have CBTC as well)
- R179 (New York City Subway car) - a similar car to be built by Bombardier Transportation that will also have CBTC
- R188 (New York City Subway car) - a similar car built by Kawasaki Railcar for the A Division that also has CBTC
