Mazda patent shows rotary placement in complex AWD hybrid layout

If we were playing alt-powertrain Bingo, a recent Mazda patent application filed in Japan would be one or two letters from victory. What's exciting about the patent, discovered by Japanese outlet T's Media via Motor Trend, is that while it makes a case for an internal combustion engine of any configuration, one of the drawings showing a rotary engine. The wild bit is that the whole powertrain comprises the ICE, a transaxle, two tiny in-wheel electric motors turning the front wheels, a third electric motor in the driveline, a capacitor, a lithium-ion battery, and three inverters. Motor Trend parsed the mechanics, and the way it reads, Doc Brown couldn't have done a better job. The rotary engine at the front turns the rear wheels, but not directly. Instead of a flywheel on back of the engine, the drawing shows a 25-kW electric motor and an inverter, then a driveshaft running to the transaxle. Along the axis of the transmission tunnel in a normal car, between the inverter and the transaxle, lies a 3.5-kWh battery running at 48 volts. MT writes that the electric motor can add its output to the ICE output to drive the rear wheels, or the e-motor can turn the rear axle on its own. Up front, two inverters and a double-layer capacitor join the ICE in the engine bay. The capacitor and tiny hub motors in the front wheels run at 120 volts, a higher voltage than the rest of the electrical system, so that the small in-wheel motors can generate the same torque as a larger motor running at a lower voltage. The AWD system acts on-demand. Given the signal, the capacitors discharge their energy to the wheel motors, and recover energy from braking. When the capacitors are at full charge, they send excess regen energy to the lithium-ion battery; conversely, the battery can recharge the capacitors when they're low and the front hub motors need power. The patent explains that the ICE works with the rear e-motor to drive the rear wheels at low speeds, the front motors called on to "generate an output only when a large output is required in the high vehicle speed range." The rather complicated system is focused on providing the benefits of a hybrid system and all-wheel drive, but at lower weight than one would expect. A rotary serves due to its compactness, but one of the drawings shows an engine with a V layout. Hub motors get dinged for adding unsprung weight, hence the small motors here.

Lexus, Mazda win KBB 5-Year Cost To Own Awards

We focus a lot on what new cars are like to drive, but it's difficult on a one-week loan to really get a sense of what a car is like to live with. Sure, we try to recreate that sense with our long-term vehicles, but even after a year, it's impossible to know fully learn about a car, particularly in terms of reliability and cost of repairs. For 2014 model year vehicles, Kelley Blue Book has put together a list of the most affordable vehicles over a five-year period.
At the tippy top of the list are Mazda and Lexus, with the Zoom-Zoom automaker winning the award for best non-luxury brand. Lexus, meanwhile, was the most affordable luxury marque over a five-year period. It's interesting to note, though, that not a single Mazda won its segment in this year's awards.
General Motors did quite well, taking eight segments, including both the subcompact and plug-in segments, with the gas-powered Chevrolet Spark and Spark EV. The Chevy Camaro SS and ZL1 took the high-performance car award. Toyota was well represented, with five winners split between the main brand (Corolla, Prius C and Tacoma) and Lexus (LS and RX).

2021 Mazda CX-30 2.5 S gets new name, adds tech, keeps same power

For its second model year, Mazda's in-betweener compact crossover is getting a new-ish name: the 2021 Mazda CX-30 2.5 S. No, those extra digits at the end aren't a trim level. The 2.5 S is apparently part of the name. They also don't indicate a boost in output, as the CX-30 won't be following the example of the recently announced Mazda3 2.5 Turbo. They're all for show. Instead, Mazda adds some new connectivity and safety features to the package. Apple CarPlay and Android Auto are now standard across the lineup. They join Mazda Connected Services with a three-year trial and in-car WiFi hotspot with a six-month or 2GB trial, and they pair with the carryover 8.8-inch center infotainment screen that is controlled by a rotary dial mounted behind the gear shifter. The CX-30 2.5 S keeps as standard the 7-inch reconfigurable digital gauge display, Bluetooth phone and audio, two front USB ports and electronic parking brake. There are also some new safety options to go with the standard i-Activsense package, which includes Mazda’s version of adaptive cruise control with stop and go function, smart braking support, a driver attention alert, lane departure warning with lane-keep assist and high-beam control. Upgrade to the CX-30 2.5 S with Select Package, the second of four trim levels, and you get blind-spot monitoring with rear cross-traffic alert, side mirror turn signals and Mazda Advanced Keyless Entry, plus a leather-wrapped steering wheel and shift knob, leatherette seating and upgraded, 18-inch wheels, among other perks. Step up to the Preferred Package and you get features like a power moonroof, heated front seats and black gloss front grille. The top-tier Premium Package, meanwhile, brings a Bose 12-speaker sound system, a three-month SiriusXM trial subscription, navigation, windshield-projected Active Driving Display, power liftgate, paddle shifters and LED head- and taillights, among other features. As before, power comes from the Skyactiv-G 2.5-liter inline-four that it shares with the Mazda3. It makes 186 horsepower and 186 pound-feet of torque and is mated with a six-speed automatic transmission. The standard setup is front-wheel drive and G-Vectoring Control Plus, but predictive i-Activ all-wheel drive with off-road traction assist is an option across the range for an extra $1,400. Base price creeps up by $55 from 2020 to an even $23,000, including the $1,100 destination fee. Related Video: This content is hosted by a third party.
