Question: How many cylinders are in the engine of the hatchback revealed by Honda at the 1997 Tokyo Motor Show?
Context: CVCC is a trademark by the Honda Motor Company for an engine with reduced automotive emissions, which stood for "Compound Vortex Controlled Combustion".  The first mention of Honda developed CVCC technology was done by Mr. Soichiro Honda February 12, 1971, at the Federation of Economic Organizations Hall in Otemachi, Chiyoda-ku, Tokyo.  Honda's engineers at the time, Mr. Date conferred with Mr. Yagi and Mr. Nakagawa about the possibility of creating lean combustion via a prechamber, which some diesel engines utilized.  The first engine to be installed with the CVCC approach for testing was the single-cylinder, 300 cc Honda EA engine used in the Honda N600 hatchback in January 1970.  This technology allowed Honda's cars to meet Japanese and United States emission standards in the 1970s without a catalytic converter.  A type of stratified charge engine, it first appeared on the 1975 "ED1" engine.  As emission laws advanced and required more stringent admissible levels, Honda abandoned the CVCC method and introduced PGM-FI, or Programmed Fuel Injection on all Honda vehicles.  Some vehicles in Japan had a combination of electronically controlled carburetors, called PGM-Carb on specific, transitional Honda D, E and ZC engines. The Honda S660 is a two-seat sports car which fits in the very small Kei car category.  It is manufactured by the Japanese manufacturer Honda.  The car weighs approx 830kg with manual transmission and 850kg with CVT auto.  A prototype was shown at the November 2013 Tokyo Motor Show, the major Japanese auto show event.  It is the successor to the Honda Beat.  The naming convention of using the letter "S" followed by the engine displacement is a long held Honda tradition going back to Honda's first production car, the Honda S500. The Honda VTX series is a line of Honda V-twin cruiser motorcycles inspired by the Zodia concept shown at the 1995 Tokyo Motor Show.  The Honda VTX 1800 was launched in 2001 as a 2002 model.  At the time this bike was introduced the Honda VTX engine was the largest displacement production V-twin in the world, but that distinction would be short-lived as the VTX1800 was superseded in 2004 by the 2-liter . , Nevertheless, the VTX 1800 still produced better 0-60 mph and 1/4 mile times. The Daihatsu Copen is a 2-door roadster with an aluminium retractable hardtop built by the Japanese car company Daihatsu.  It debuted at the 1999 Tokyo Motor Show, as the Daihatsu Copen concept.  The second generation model debuted as the Kopen (Future Included) at the 2013 Tokyo Motor Show. The Honda D series inline-four cylinder engine is used in a variety of compact models, most commonly the Honda Civic, CRX, Logo, Stream, and first-generation Integra.  Engine displacement ranges between 1.2 and 1.7 liters.  The D Series engine is either SOHC or DOHC, and might include VTEC variable valve timing.  Power ranges from 62 hp in the Logo to 130 PS in the Civic Si.  D-series production commenced 1984 and ended 2005.  D-series engine technology culminated with production of the D15B 3-stage VTEC (D15Z7) which was available in markets outside of the United States.  Earlier versions of this engine also used a single port fuel injection system Honda called PGM-CARB, signifying the carburetor was computer controlled. The Honda Capa, with the Honda series code GA4 and GA6, is a supermini MPV five-door hatchback produced by Honda between 1998 and 2002.  It was introduced at the 1997 Tokyo Motor Show as the concept car "J-MW."  It was introduced for retail sale April 24, 1998.  The only engine the Capa had was the 98 hp 1.5L Honda engine, the D15B, with either a 4-speed automatic transmission (front-wheel drive only) or a CVT called "Multimatic S".  September 16, 1999 a 4WD version of the Capa was released, using Honda's Full-Time four-wheel-drive system.  Brake Assist was offered as standard equipment.  Due to disappointing sales the Capa, short for "capacity", it was discontinued and replaced by the Honda Mobilio and Honda Fit.  It was sold in Japan at two Honda dealership sales channels "Honda Primo", and "Honda Verno". The Maybach 57 (chassis no.  W240) and 62 (chassis no.  V240) were the first automobile models of the Maybach brand since the brand's revival by DaimlerChrysler AG (now Daimler AG).  They are derived from the Benz Maybach concept car presented at the 1997 Tokyo Motor Show.  The concept car was based on the Mercedes-Benz S-Class sedan, as are the production models.  The Luxury Brand Status Index 2008 voted the Maybach first place, ahead of Rolls-Royce and Bentley.  The models ceased production in 2013, due to continued financial losses for the marque, and sales at one-fifth the level of the profitable Rolls-Royce models. The Subaru Elten was a concept hybrid 4WD hatchback manufactured by Subaru.  Introduced at the 1997 Tokyo Motor Show.  The vehicle was a successor to the 360 taking many design elements from the vehicle even a similar grille.  But the design was later scrapped for a different model. The Honda N-One (corporately styled "Honda N-ONE") is a kei car produced by Honda for the Japanese market.  It was previewed at the 2011 Tokyo Motor Show and went on sale on November 1, 2012.  With the Honda N-Box, it is part of a renewed lineup of "Kei" class city cars.  The use of the letter "N" in the name was used by Honda for the late 1960s and 1970s Honda N360. The Honda J-VX was the first hybrid sports car concept to employ Honda's Integrated Motor Assist electric hybrid system and was initially unveiled at the Tokyo Motor Show in October, 1997.  It achieved 70mpg (30km/l) and featured a 1.0 liter, 3 cylinder VTEC engine, supercapacitor electrical storage, an all-glass roof, airbag-like "air belts", used lightweight materials, and aerodynamic design.  Eventually it would evolve into the Honda VV, a Pre-production prototype of the Honda Insight.
Answer: inline-four cylinder engine
