Who's in hybrid SUVs? Full Hybrid (HEV), Plug-in Hybrid (PHEV) and Mild Hybrid (MHEV) Compared
How mild hybrid (MHEV), full hybrid (HEV) and plug-in hybrid (PHEV) SUVs work, and how fuel use is measured.
Automotive, Mobility & Energy
Hybrid SUVs (HEV/PHEV), home solar panels, winter tires, ECE 22.06 helmets and motorcycle gear, and battery chemistries beyond lithium-ion.
Who's in home solar? Rooftop Solar Components (Monocrystalline Panels, Hybrid Inverters, LFP Batteries) Compared
Grid-tied, off-grid and hybrid rooftop solar systems, plus TOPCon monocrystalline panels, string vs micro inverters and LFP batteries.
Who's in winter tires? Wet and Snow Braking, Tread and Compound Compared
Premium makers that win ADAC and AutoBild winter tire tests (Continental, Michelin, Goodyear, Bridgestone, Nokian), the 3PMSF mark, and winter vs all-season tires.
Who's in motorcycle gear? Helmet Standards, Protective Clothing and Fit Compared
Thermoplastic vs composite/carbon helmet shells, the newer ECE 22.06 (rotational impact) standard, CE EN 17092 AAA jackets and D3O/Level 2 armor.
Who's in battery alternatives? LFP, NMC, Sodium-Ion and Solid-State Compared
Energy density (Wh/kg), fire safety, cycle life and cold-weather behavior of LFP (LiFePO4), NMC, sodium-ion (Na-ion) and solid-state batteries.
Who's in for heat pumps and HVAC systems? Air-Source and Ground-Source Cycle and COP Efficiency Table
Air-source (monobloc vs split) and ground-source heat pumps compared: underfloor heating vs old radiators, R32 vs R290 refrigerant, and winter COP.
