The engine used in the Ford GT90 concept sports car is a 90-degree, quad-turbocharged, V12 engine; which itself is based on the Ford Modular V8 engine.{{Cite web|url=https://drivetribe.com/p/the-story-of-the-ford-gt90-the-TxoqshMGRpe1e7fXI2Eu9Q?iid=b9p3ZBEsSfSBrme2sJqqSA|title=The story of the Ford GT90 - the 720 horsepower hypercar that should've been|date=21 August 2018}}{{Cite web|url=https://www.ultimatespecs.com/car-specs/Ford/23131/Ford-GT90-V12.html|title=Ford GT90 V12 Technical Specs, Dimensions}}{{Cite web|url=https://www.supercars.net/blog/1995-ford-gt90-concept/|title=1995 Ford GT90 Concept | Ford|date=20 April 2016}}{{Cite web|url=https://www.motortrend.com/reviews/ford-gt90/|title=Ford GT90 - Motor Trend Magazine|date=December 1995}} It was Ford's first V12 since their Lincoln division's Lincoln-Zephyr V12 engine in 1948.
A 6.0-liter V12 engine was used in the Ford Indigo concept, but that engine was based on the Ford Duratec V6 engine, which has no relation to the V12 used in the GT90, and is also less powerful.{{Cite web|title=Race track design and technology drives the Ford Indigo concept sports car|url=https://www.fordfan.de/modellinfos/1996/01/02/race-track-design-and-technology-drives-the-ford-indigo-concept-sports-car|access-date=2021-02-04|website=fordfan.de|language=de}}
Overview
The GT90's 48-valve V12 is constructed on an aluminium block and head, displaces {{cvt|5927|cc|L cc cuin|order=out|1}}, and produces an estimated {{cvt|720|hp|kW PS|0}} and {{cvt|660|lbft|Nm|0}} of torque.{{cite web|url=http://www.ultimatecarpage.com/car/899/Ford-GT90-Concept.html|title=Ford GT90 Concept|author=Wouter Melissen|website=UltimateCarPage}} It has a redline of 6,300 rpm. It is equipped with a forced induction system that uses four Garrett T2 turbochargers.{{Cite news|url=https://www.motortrend.com/news/ford-gt90-test/|title=Driving The Ford GT90 - Motor Trend|date=1995-12-01|work=Motor Trend|access-date=2018-09-09|language=en-US}} The engine architecture was based on the 90-degree Ford Modular engine family, based on the same architecture and bore as the 4.6-litre V8 engine, but with four more cylinders added, two more in each cylinder bank, and a shorter stroke. This yielded a 90-degree V12, with a {{cvt|90.2|mm|in}} bore and a {{cvt|77.3|mm|in}} stroke with the cylinders arranged in two banks in a single casting.{{cite web|url=http://www.supercars.net/blog/1995-ford-gt90-concept/|title=1995 Ford GT90 Concept|last1=D|first1=Nick|website=Supercars|date=20 April 2016}}
The V12 engine, unique to the GT90,{{cite web |url=http://jalopnik.com/the-ford-gt90-may-have-been-the-greatest-concept-car-ev-1441257780 |title=The Ford GT90 May Have Been The Greatest Concept Car Ever |last1=George |first1=Patrick |date=4 October 2013 |website=Jalopnik }} was developed by using a Lincoln Town Car as a test mule, in which they put the prototype engine in order to refine it.
