Toyota Hypes New Four-Cylinder Engine: '600 HP Is Easily Possible'
new family of four-cylinder combustion engines
, to be offered in both naturally aspirated and turbocharged flavors. These upcoming gas engines, planned with displacements of 1.5 liters and 2.0 liters, are said to be smaller and lighter. While efficiency is the primary goal, performance won't be overlooked. The larger of the two engines is getting the Gazoo Racing treatment, already previewed in the GR Yaris M concept.
The wild
mid-engine hot hatch
took us by surprise when it debuted as a concept at the Tokyo Auto Salon in January. Sporting the new 'G20E' engine mounted above the rear axle, the pocket rocket featured an IHI turbocharger, pushing output to around 400-450 hp. However, German magazine
Auto Motor und Sport
has now learned from Toyota engineers that there's potential for much more: 'With a larger turbocharger, more than 600 hp is easily possible.'
That would be more than double what the 'G16E-GTS' produces in the GR Yaris, GR Corolla, and
Lexus LBX Morizo RR
with their turbocharged 1.6-liter three-cylinder engine. However, while 600+ hp is technically achievable with a larger turbo, Toyota will likely run into a major obstacle: stricter regulations. It may (and probably will) be forced to detune the 'G20E' to reduce CO₂ emissions. However, even an output starting with a '4,' let alone a '5,' would be impressive. In race car applications, an uncorked version could fully exploit the engine's potential.
Expect to see the new four-cylinder engine to power many performance cars, as the 2.0-liter is being engineered for both longitudinal and transverse installations. It can sit at the front or rear, making it a possible backbone for Gazoo Racing's future lineup. Toyota has teased a potential
return of the Celica
and/or MR2, while also promising that the Supra will live on beyond the current generation. A next-gen GR86 could also be a natural fit, assuming it's in development.
Toyota told
Auto Motor und Sport
that it's been testing the 'G20E' in the GR Yaris M for some time. However, we recall sharing a video featuring a Lexus IS prototype over a year ago. The stripped-down sedan was fitted with one of the new engines and
sounded highly promising
, possibly featuring the most exciting member of the new four-cylinder lineup. At the time, Toyota's engine boss Takashi Uehara hyped the 'totally new engine' as being intended for 'car lovers who expect a little something extra.'
Interestingly, one Toyota engineer strongly suggested the 'G20E' will be highly tunable (2JZ redux?): 'We left enough space between the cylinders so that the engine can be bored out considerably.' Another engineer claimed the Yaris M's 'performance is incredible,' adding that the hot hatch's wheelbase had to be slightly extended to accommodate the engine mounted behind the driver.
It's worth noting that Toyota's new four-cylinder family is part of a broader initiative alongside two other Japanese automakers to
extend the life of combustion engines
. Mazda is developing rotary engines as range extenders, while Subaru continues refining its boxer engine. Hybridization is a shared objective, but the trio is also exploring carbon-neutral fuels like liquid hydrogen, biofuel, and synthetic fuel.
Beating a dead horse? Toyota doesn't think so. In early 2024, Chairman Akio Toyoda said he doesn't believe EVs will ever exceed a 30% market share. However, a recent
International Energy Agency (IEA)
study
found that over 20% of new cars sold last year worldwide didn't have a combustion engine. Additionally,
BloombergNEF
projects EV sales will increase by 25% in 2025. That report also predicts nearly two-thirds of global EV demand this year will come from China, followed by Europe at 17% and the United States at 7%.

Asian shares retreat, tracking tech losses on Wall Street
TOKYO (AP) — Asian shares retreated on Wednesday, tracking a decline on Wall Street led by technology shares including Nvidia and other stars that have been riding the mania surrounding artificial-intelligence. Benchmarks fell in Japan, South Korea and Taiwan, pulled lower by selling of computer chip makers. Tokyo's benchmark Nikkei 225 declined 1.7% to 42,787.28. Japan reported its exports fell slightly more than expected in July, pressured by higher tariffs on goods shipped to the U.S. Computer-chip equipment makers Advantest plunged 6.6% and Disco Corp. dropped 4.7%. Chip maker Tokyo Electron lost 1.9%. and Lasertec Corp. lost 1.8%. The Taiex in Taiwan fell 2.4% after chip maker TSMC dropped 3.8%. Hong Kong's Hang Seng slipped 0.6% to 24,980.20 while the Shanghai Composite index edged 0.1% lower to 3,725.22 after China's central bank opted to keep the benchmark interest rate unchanged, as markets had expected. Australia's S&P/ASX 200 gained 0.2% to 8,917.60. South Korea's Kospi dropped 1.4% to 3,096.09, as North Korean leader Kim Jong Un condemned South Korean-U.S. military drills that began this week, and vowed a rapid expansion of his nuclear forces to counter rivals, according to North Korean state media. On Wednesday, the S&P 500 fell 0.6% to 6,411.37, for a third straight loss. It remains near its all-time high set last week. The Dow Jones Industrial Average added less than 0.1% to 44,922.27, and the Nasdaq composite slumped 1.5% to 21,314.95. The heaviest weight on the market was Nvidia, whose chips are powering much of the move into AI. It sank 3.5%. Another AI darling, Palantir Technologies, dropped 9.4% for the largest loss in the S&P 500. It's seen bets build up sharply that its stock price will drop, according to S3 Partners. Only Meta Platforms has seen a bigger increase this year in what's called 'short interest,' where traders essentially bet a stock's price will fall. Meta, the owner of Facebook and Instagram, sank 2.1%. Criticism has been rising that stock prices across Wall Street have shot too high, too fast since hitting a bottom in April and have become too expensive. Palantir's stock came into Tuesday with a tremendous gain of 130% for the year so far. The priciness of AI-related shares and potential for further trade restrictions in the strategically important chip industry prompted investors to sell. Home Depot's gain of 3.2% was the biggest reason the Dow did better than other indexes. The retailer reported results for the latest quarter that were a bit short of what analysts expected, but it delivered growth in revenue and stood by its prior forecasts for revenue and profit over the full year. The week's headliner for Wall Street is likely arriving on Friday. That's when the chair of the Federal Reserve, Jerome Powell, will give a highly anticipated speech in Jackson Hole, Wyoming. The setting has been home to big policy announcements from the Fed in the past, and the hope on Wall Street is that Powell may hint that cuts to interest rates are coming soon. The Fed has kept its main interest rate steady this year, primarily because of the fear of the possibility that President Donald Trump's tariffs could push inflation higher. But a surprisingly weak report on job growth across the country may be superseding that. Traders on Wall Street widely expect the Fed to cut interest rates at its next meeting in September in order to give the economy a boost. Treasury yields have come down notably in the bond market as a result, and they eased on Tuesday. Strategists at Bank of America warn that Powell may not sound as inclined to cut interest rates as the market is expecting. He could remain non-committal and discuss the possibility of a worst-case scenario for the economy called 'stagflation.' The Fed has no good tool to fix that situation, where the economy stagnates at the same time as inflation remains high. In other dealings early Wednesday, benchmark U.S. crude added 12 cents to $61.89 a barrel. Brent crude, the international standard, gained 11 cents to $65.90 a barrel. The U.S. dollar edged down to 147.52 Japanese yen from 147.66 yen. The euro cost $1.1636, down from $1.1648. ___ AP Business Writer Stan Choe contributed.

Thai Data Center Capacity May Triple on Surging Demand for AI
Thailand's data center capacity is expected to triple in the next three years as investments of about $6.5 billion pour into the sector to meet surging demand for cloud computing and artificial intelligence. The nation's capacity is expected to rise to about 1 gigawatts in 2027 from 350 megawatts in 2024, said Supparat Singhara Na Ayutthaya, vice chairman of the Thai Data Center Association. A data center requires an investment of about $10 million for each megawatt, he said.
