Scion FR-S pitted against oldtimers RX-8 and S2000

There are very few vehicles available today that compare directly with the Scion FR-S and Subaru BRZ twins. A case could be made for the Mazda MX-5 Miata, and possibly even six-cylinder versions of American coupes like the Ford Mustang. Pretty much everything else is either too expensive or is powered by the wrong set of wheels.
The boys from EverydayDriver on YouTube decided the only fair way to judge the inherent qualities of the Toyobaru twins was to pit them against two standard-bearers of years past: The Honda S2000 and Mazda RX-8. Neither of these cars is an exact matchup, with the Honda boasting a convertible top and the RX-8 offering more practicality via a rear seat and two reverse-opening doors for easier access. What they do offer, however, are similar performance stats and proven reputations for excellent handling.
None of this talk answers the real question, though: Which one wins the comparison test? Scroll down to watch the video, and be prepared for something of a surprise conclusion.

2014 Mazda6: July/August 2013

Our newest long-termer - the Soul Red 2014 Mazda6 seen here - arrived in my driveway at the end of June. Without hesitation, I immediately put it to work as a daily driver, carpool bus and family vacation sled, and it accomplished all of those tasks with aplomb. Now, more than 4,000 miles down the road, I am left convinced that Mazda's latest midsize sedan is one of the best in its segment.
During the past 60 days, I have subjected the Mazda6 to scorching travel across Southwestern deserts, wheezing climbs over 8,000-foot-high Sierra Nevada mountain passes and basking in the cool ocean breezes of Malibu. It traveled with four passengers and a full load of luggage from Los Angeles to Lake Tahoe, and it braved the bumper-to-bumper freeway congestion on a weekday trip down to San Diego. It accomplished everything that was asked of while hardly skipping a beat - it has only required a regular sip of unleaded fuel to keep it moving forward.

Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.
