That is a four cylinder. There was a V8 version, the TR8 but not many were sold, at least in the US and was the last of the sports cars under the Triumph name. They made a couple more models into the very early 80's then replaced the real Triumphs with rebadged hondas and that was the ugly end of the line.
BMW now owns the Marque but nothing has been made under it in at least 35 years.
