Twice Tested, The New Toyota Supra Makes More Horsepower Than Listed

Twice tested, the new Toyota Supra makes more horsepower than listed

Two magazines put two 2020 Toyota Supras on two dynos in two parts of the country on two different days. Both magazines came to the same result: Toyota underrated the power figures of the particular Supras being tested. In May, Car and Driver strapped a Supra to an all-wheel drive Dynojet dynamometer in Livernois, Michigan. CD's figures came to 339 horsepower and 427 lb-ft of torque at the wheels. After that, Motor Trend strapped a Supra to a Mustang eddy-current chassis dynamometer in Torrance, California. MT's weather-corrected numbers came to 332 hp and 387 lb-ft.

Toyota's official numbers for the 3.0-liter turbocharged inline-six cylinder sourced from BMW are 335 hp and 365 lb-ft, measured at the crank. Using the hoary conventional wisdom of driveline and hydraulic losses causing 15 percent of power to evaporate before reaching the wheels, we'd expect the Supra's power at the contact patch to be around 285 hp and 310 lb-ft. Even updating that parasitic loss figure to 10 percent for a modern drivetrain, we're still at around 300 hp and 328 lb-ft.

This 1,000-horsepower, Rear-drive Toyota Corolla Im Could Be Yours

This 1,000-horsepower, rear-drive Toyota Corolla iM could be yours

We were amazed last year when we learned that Papadakis Racing built Fredric Aasbo a rear-drive, 1,000-horsepower 2017 Toyota Corolla iM for drifting. Now we're amazed that the car could end up in the hands of an average person, because the car is currently going for auction on Bring A Trailer.

Just as a quick recap for those that might have missed hearing about the car last year, the little Toyota hatch features a turbocharged and nitrous-injected 2.7-liter 2AR-series Toyota four-cylinder. Variants of that engine are found in older Toyota RAV4s and Camrys. According to Bring A Trailer, the engine hits 1,000 horsepower and 850 pound-feet of torque when running on E85. Power goes through a four-speed dog box manual transmission to the rear wheels.

What A 181-horsepower 2019 Mazda Mx-5 Miata Means For Us, And You

What a 181-horsepower 2019 Mazda MX-5 Miata means for us, and you

Last month, we reported on a VIN filing dug up by Road & Track that showed that the 2019 Mazda MX-5 Miata's 2.0-liter Skyactiv-G engine would get a power bump, from 155 to 181 net horsepower. As for how the 2019 Miata would make that extra power, we heard rumors it'd utilize a new cylinder head allowing higher revs, accounting for that extra power. Now we have what appears to be a leaked document from Mazda Canada showing exactly where that extra power comes from.

According to the document posted at Miata.net (registration required to see the image), Mazda will alter camshaft lift and valve size on both the intake and exhaust side, fit freer-flowing exhaust, and smooth and enlarge the piping on the air intake side. There are also internal engine modifications: lighter pistons with lower crowns for better swirl in the combustion chamber, lighter connecting rods, and a crankshaft balanced for higher-RPM operation. All those extra revs mean extra vibration and noise, so Mazda will ditch the single-mass flywheel for a "low-inertia" dual-mass flywheel – which will attempt to find a nice balance between DMF damping action and SMF directness. Overall, it's a pretty serious engine revision with some driveline changes that will heavily affect the driving characteristics of a fantastic driver's car.

The 2018 Kawasaki Ninja H2 Sx Is A 201-horsepower Supercharged Cruiser

The 2018 Kawasaki Ninja H2 SX is a 201-horsepower supercharged cruiser

When it comes to power-to-weight ratios, motorcycles are on a whole other level than cars. 200ish horsepower might make for a reasonably quick car (think Honda Civic Si), but in a motorcycle, 200 horsepower is an absolutely bonkers figure. That's part of what makes the 201-hp 2018 Kawasaki Ninja H2 SX and it's 2.8 pounds-per-pony so impressive (we're talking Bugatti Veyron power ratios here). That and the bright green paint.

This is the third supercharged motorcycle from the Japanese manufacturer, following on the H2 and H2R. According to Asphalt and Rubber, the model comes in two flavors, the black H2 SX and the green H2 SX SE. The SE comes with a thin TFT color dash, cornering lights, launch control and a quickshifter.

Suzuki Unveils Maximum 350-horsepower Df350a Outboard

Suzuki Unveils Maximum 350-Horsepower DF350A OutboardSuzuki unveiled the DF350A flagship outboard, which has realized horsepower of 350PS, the maximum output in Suzuki's lineup of outboards. Suzuki Dual Prop System is adopted for the first time on Suzuki outboards. The system efficiently converts engine output into forward thrust by combining two contra-rotating propellers. Plus, the smaller gear case decreases underwater resistance to realize high running performance and directional stability.

The newly-developed four-stroke V6-cylinder engine is equipped with features such as the Direct Intake System to realize superb output performance and high fuel-efficiency. Dual injectors per cylinder and optimal combustion chamber shape increase charging efficiency and combustion efficiency to realize superb output performance. Suzuki flagship outboard DF350A will be produced at the Toyokawa Plant in Japan, and launched in the US from July. Subsequently, they will be launched globally including Japan and Europe.

One More Reason Why The Civic Si Only Makes 205 Horsepower

One more reason why the Civic Si only makes 205 horsepower

When Honda revealed the production-spec Honda Civic Si at the New York auto show, we learned some of the reasons why Honda only gave the Civic Si 205 horsepower. One reason was the desire to keep the price down, hence the upgraded turbo 1.5-liter engine instead of a detuned Type R engine. Another was the want to provide the Si with a different, more precise character than its competition. It turns out there was yet one more reason, and that was durability.

Automotive News spoke with one of Honda's product planners, and he revealed to the outlet that making the engine capable of lasting "hundreds of thousands of miles" was a key consideration. He said that adding more power would have reduced the overall durability of the engine below what Honda was targeting.

Why Honda Played It Safe With Civic Sis Horsepower

Why Honda Played It Safe With Civic Si’s Horsepower

When Honda revealed the new Civic Si, many fans expressed a certain disappointment just by looking the key figures.

The new turbocharged model produces 205hp, which is exactly the same figure its naturally aspirated predecessor made, while peak torque got a useful bump to 192lb-ft, up from 174lb-ft of the previous model.

Why The 2018 Honda Civic Si Only Makes 205 Horsepower

Why the 2018 Honda Civic Si only makes 205 horsepower

When Honda revealed the output of the 2018 Civic Si sedan and coupe, the world was a bit confused. The car wasn't any more powerful than the 2015 Civic Si with "just" 205 horsepower. And its torque rating of 192 pound-feet was only somewhat better than that car's. Just as surprising was the fact that both numbers were well below the 306-horsepower Type R. However, according to Honda representative Davis Adams, there are reasons for Honda taking this path.

For one thing, going with a high-output 1.5-liter engine was a matter of affordability and which team developed the car. While it may have been possible to detune a Type R 2.0-liter engine, the cost would have still been high to use the engine, even in low-output form. Honda wanted to keep the price tag affordable. In addition, the Si, a North American car, was developed by the American Honda team with the standard sedan and coupe, both of which are primarily designed for the US. The Japanese team handled the hatchback and Type R, and decided from the get-go they would focus on the 2.0-liter turbo engine. Adams told us that the team in Ohio working on the sedan and coupe spent most of their time with the 1.5-liter engine, and knew that they could get more out of it. The result is the engine you know now, and the power comes mainly from a different turbo map and more boost pressure. The internals are effectively the same as in other turbo Civics.
